Sirius Kingdom[]

See also Sirius Kingdom
Has 13 Known Planets in 4 systems

  • Sirius System (28.5ly; 8.6 ly) - Sirius is also known as Alpha Canis Majoris and Gliese 244. The brightest star in the sky. A hot blue-white main sequence star with a white dwarf (the "pup") orbiting it. Orbit distance varies between 8.1 and 31.5 ly and takes 50 years to navigate. The habitable zone of Star A is centered 4.25 AU from the star and may be disrupted due to the presence of Star B. Long thought to be a part of the Ursa Major Moving Group (also called the "Sirius Group"), it was found to be too young to be a member and not heading in the right direction. The brightest star within a large distance from the Sun. Star B is about the same mass as the Sun, but is almost the same size as the Earth. It may have evolved from a 5 solar massed B-type main sequence star. It is the nearest and first discovered white dwarf star. Dust has been detected from the system, probably from material sluffed off from Star B. A search in 2008 using high contrast imaging for planets within 10 Jupiter masses within 25 AU of the binary star turned up negative.
    • Kapteyn's Star System (7.5 ly) - Kapteyn's Star is also known as VZ Pic, Gl 191, HD 33793, and Cordoba Zone 5 hours 243. Kapteyn noticed that a star was missing from a catalog until its new position was found. Has the second highest proper motion of any stars. Also informally called Proxima Pictoris. Nearby large and old Red Dwarf star system and nearest Halo object thought to be a remnant of the nearest and largest global cluster, Omega Centauri, which is 16,000 ly away and shredded by the Milky way 11.5 BYA, and born while that was still a separate galaxy. 2.5 times as old as the Sun and born when the Universe was only 2 BYO. Was within 3 light years of Epsilon Eridani 31,500 years ago. Will be on the other side of the galaxy in 100 MY. Is a sub-dwarf or main sequence star. Has two planets. The first is at least a 4.5 ME Super Earth (0.16 AU) and is the oldest Potentially Habitable Planet. The second is over 7 ME and beyond the HZ (0.3 AU).

Solar Principality[]

8 Known Planets

    • Solar System (8.6 ly) - Our home star system. Contains 4 terrestrial planets, 4 gas giant planets, several dwarf planets, an asteroid belt, and a kuiper belt, around a G-Class yellow dwarf star. Contains the only known habitable planet, Earth.
      • Barnard's Star System (6.0 ly) - Barnard's Star is also known as Gliese 699 and informally as Proxima Ophiuchi. Named for the astronomer E. E. Barnard, who discovered it in 1916 and was the first to measure its proper motion. Second closest star system to the Sun and the one with the highest proper motion in the sky - due to its rapid approach to the Sun. Will get as close as 3.8 ly away in 12,000 years. A red dwarf thought early on to have a planet around it found due to radial velocity method, which has been disproved. A super earth has been detected at Mercury-like distances, but beyond the frost line. Life could be possible if an additional source of heat was provided. A potential target for the 1970's Project Daedelus. The star is very ancient 11-12 Billion Years Old, and is the nearest inactive Red Dwarf Star. It may take another 40 Billion Years before it cools to become a Black Dwarf. Astronomers were surprised to discover that it was a flare star in 2003, and dubbed it V2500 Ophiuchi.
      • Wolf 359 System (7.9 ly) - Wolf 359 is also called Gl 406, and CN Leonis and informally called Proxima Leonis. Third nearest star system to the Sun and the nearest star with no known planets. It is one of the smallest Red Dwarf stars known and is a flare star and the M6 V spectral standard star. Its proper motion was first measured by German astronomer Max Wolf in 1917. It was the lowest mass and faintest star known until the discovery of VB 10 in 1944. Its temperature is so low that chemical compounds can exist in it, which is rare for a star. It is a relatively young star, less than a billion years old.

Alpha Centauri Principality[]

1 Known Planet

    • Alpha Centauri System (9.5 ly; 4.3 ly) - Alpha Centauri is also known as Rigil Kentaurus. A is also known as HD 128620 and HR 5459, B is HD 128621 and HR 5460, and C is Proxima Centauri. It is the nearest star system to the Sun. Contains a yellow dwarf star a little bigger than the Sun and an orange star a little smaller orbiting each other orbiting each other about the distance Uranus is from the Sun (varies from Saturn like to Neptune like), as well as a distant Red Dwarf companion Proxima that may or may not be orbiting the other two.

    Stellar fingerprinting suggests a high probability that a planet orbits star A, due to dearth of Iron around star. Russian astronomers announced the detection of a second planet orbiting the binary pair at 80 AU with a 100 year period, which appears to be false. The stars in the system will become markedly closer together in 2016, making observations much more difficult and one follow up failed to find it. The system is the first target for the European Cheops exoplanet space telescope.

    A planet was thought to have been discovered around star B and detected by HARPS. It would have been an Earth-massed rocky-iron planet with no atmosphere at epistellar distances around the orange dwarf star B. This would have been the least massive planet found around a sunlike star. The planet was informally and controversially named by Uwingu during a fund raising naming contest Albertus Alauda, after a participant's grandfather. Earthlike planets are not detectable in the habitable zone with present radial velocity methods. Technique for detection of planet is a source of doubt for some and it has yet to be independently verified. A team thought they might have detected a transit of this planet, but further observations showed the timing wasn't consistent. It is possible that a second further out (20.4 day period) Earth-sized planet is altering the transit times of the first. A cheap crowdfunded satellite devoted to studying this star could confirm the planets. The star was observed to be a good candidate to host a "super Habitable" planet, which would have 25% more gravity than the Earth, shallow seas, flatter landscape, higher atmospheric pressure, and the 6 BYO star would be stable for life longer.

    Proxima, a small flare star, was discovered in 1915 by Robert Ines, who named it. Long suspected planet around Proxima found not to exist. The Pale Red Dot project is dedicated to finding a planet around Proxima using dopplar spectrometry. As Proxima passes in front of two stars (once in 2014, again in 2016), any planets within 5 AU should be detectable via microlensing using the HST. It is known that no planets of Neptune sized mass exist within 1 AU and no Jovians with periods up to 1000 days, or transiting planets exist. An Earth-like planet in the habitable zone was discovered around Proxima Centauri. In 2017, a large stellar flare erupted and bombarded the planet, making it likely that the atmosphere has been completely stripped away by events such as this and not a good candidate for life. It was thought that a lot of dust existed in the system, making it feasable that the star had a rich complement of planets, but this seems to not be the case.

      • Ross 154 System (8.1 ly; 9.8 ly) - Ross 154 is also called Gliese 729 and informally Proxima Sagittarii. Nearby flare star that experiences major flares about once every 2 days. An exceptionally large red dwarf and probably young, which explains the flares. First cataloged by Frank Ross in 1925.
      • Luyten 145-141 System (10.9 ly; 15.0 ly) - L 145-141 is also known as Gliese 440, LHS 43, and WD 1142-645, and informally as Proxima Muscae. Fourth nearest white dwarf. It is likely the remains of a spectral class B main sequence star. May be a part of the Wolf 219 moving group.
      • Innes' Star System (11.2 ly; 14.7 ly) - Innes' Star is also known as Gliese (NN) 3618, L 143-23, and LHS 288. Nearby Red Dwarf with exceptionally high proper motion in Carina. Discovered by Robert Innes (1861-1933), the same astronomer who discovered Proxima Centauri. According to Wikipedia (unsourced), recent studies suggest it may harbor an unconfirmed Jupiter mass planet as small as 2.4 Jupiter masses in a 7 year orbit.
      • DENIS J081730.0-615520 System (; 16 ly assumed, nearest to Innes' Star) - DENIS J081730.0-615520 is abbreviated as DEN 0817-6155 and also known as 2MASS 08173001-6155158. It is the second nearest isolated T-Class brown dwarf to the Sun and the brightest in the sky (it had been missed before due to its proximity to the galactic plain). In the constellation Carina.It discovered in 2010 and has about 15 times the mass of Jupiter. Methane has been detected in its atmosphere.

Tau Ceti Principality[]

Has 5 Known Planets in 2 systems

    • Tau Ceti System (12.3 ly; 11.9 ly) - Tau Ceti is also known as HD 10700, HR 509, and Gl 71. The nearest single G-class yellow dwarf to the sun, somewhat smaller than the Sun. A popular science fiction subject and one of two targets of SETI-forerunner Project Ozma in the 1960s. Despite being somewhat older than the sun, it has an extensive asteroid and/or comet field 10-50 AU, with the bulk between 35 and 50 AU. It has about ten times as much material as the Sun. This would make life difficult. It is a metal deficient star, so it is thought less likely to host rocky planets. Traditional dopplar spectrometry has ruled out any large Jupiter sized planets at Jupiter like distances or closer in, which was thought to be good for any potentially habitable planets. Five candidate rocky super Earth planets were detected though using a new method of planetary detection. This method made predictions of the stellar "noise" activity that might obscure detection of a planet based on the long history of dopplar measurements done on this system. Deviations from this prediction pointed towards the existence of planets. Confirmation using more established methods is needed. These planets are labeled b through f as you go outward, span 0.1 AU to 1.35 AU, and get larger the further you go out (at least 2 ME to 6.6 ME). The outermost two are near the habitable zone and were originally hailed as possibly being the nearest and smallest known habitable planets. More recent modeling indicates they are not actually habitable though. Planet e is probably too close to the star and only in the HZ if generous assumptions are made. Planet f has probably only been in the habitable zone for about a billion years as a result of its star becoming hotter, which might make biosigns difficult to detect from Earth, considering it took 2 BY for biosigns to become detectable around the Earth. Since the star has a higher magnesium to silicon ratio than the Sun, these planets compositions could be quite different that the Solar System's. The lower mantles could be dominated with ferropericlase, which is not very viscious, which may make the rocks of the mantle flow easier than on Earth, affecting volcanism and tectonics. One of 5 PICTURE-C targets selected for sub-orbital coronograph observation.
      • YZ Ceti System (1.6 ly; 12.1 ly) - YZ Ceti is also called L 275-22 and Gl 54.1. It is a nearby Red Dwarf flare star that's only 1.6 ly from Tau Ceti.
      • Luyten 726-8 System (3.5 ly; 8.7 ly) - Luyten 726-8 is also known as Gliese 65 and Luyten 726-8 and informally Proxima Ceti. It is the 6th nearest star system to the Sun. Nearby binary star system of red dwarves a distance of 2 to 9 AU from each other. Star A is also called BL Ceti, while Star B is the most famous flare star, called UV Ceti (arch-type for UV Cetic class flare stars). In 31,500 years, it will pass within only 0.93 ly of Epsilon Eridani, which may stir up comets in any Oort Clouds in these systems. It is possibly a member of the Haydes Stream.
      • Van Maanen's Star System (6.2 ly; 14.3 ly) - Van Maanen's star is also called Gl 35 and informally Proxima Piscium. The nearest single White Dwarf star, the third discovered, and the first solitary white dwarf discovered. Has more neighboring stars within 10 ly than any other star within 20 ly of the Sun, but none of them is as close as the Alpha Centauri is from the Sun. Several inconsistent studies suggest planets, but none confirmed. A plate from 1917 was discovered that showed evidence of a consumed planet in the star, the earliest evidence for an exoplanet.
      • Giclas 158-27 System (6.8 ly; 15.3 ly) - G 158-27 is also called GJ 1002 and LHS 2. Nearby Red Dwarf in Cetus that is remarkable in that no flare activity has detected, suggesting an ancient age.
      • TZ Arietis System (7.2 ly; 14.5 ly) - TZ Arietis is also known as L 1159-16 and Gliese 83.1. Nearby Red Dwarf flare star.
      • Luyten 722-22 System (7.3 ly; 17.0 ly) - L 722-22 is also known as GJ 1005. Nearby double Red Dwarf system in Cetus.
      • Ross 780 System (10.2 ly; 8.2 ly) - Ross 780 is also known as Gl 876 and the flare star IL Aquarii. Very nearby quadruple planet system and the first Red Dwarf found to have planets. The innermost planet (d, Hot Superterran, rocky-water) was the first found rocky planet around a normal star (the first true Super-Earth, at epistellar distances). The outer three planets c (Warm Saturnian), b (Warm Jovian), and e (Cold Neptunian) are in 1:2:4 (30d/60d/120d) resonance (the exoplanet resonance and first triple-resonant planets discovered). The outermost planet has a Mercury-like orbit. Planet b is second discovered by ELODIE after 51 Peg b and the second to have its mass exactly measured and the first to have done so by astrometry.
Epsilon Eridani Duchy[]
      • Epsilon Eridani System (5.5 ly; 10.5 ly) - Ran (Epsilon Eridani) is the nearest single non-red dwarf star to the Sun, also known as HD 195019, Gl 144, and HR 1084. It is a member of the Ursa Major star association and close encounters to other stars is relatively common. One of the first stars found to have a dust disk, with several potential planets suspected in the gaps early on, and later on of the earliest nearest system with confirmed planets. Has an inner asteroid belt at 3 AU, Jovian planet AEger at 3.4 AU, outer asteroid belt at 20 AU, and Kuiper Belt at 35-100 AU. A planet is proposed to be just outside the outer asteroid belt, and another just before the Kuiper belt.Because the star is very chromospherically active, doubts were cast on planet's b's existence. Hubble then confirmed its existence with astrometrics and found to be orbiting in the plane of the dust disks, which supported the theory that planets are born from dust disks and yielded a precise mass of 1.5 MJ. The planet b was originally thought to be extremely eccentric (2-10 AU), but later discovery of the inner asteroid belt suggests it is more moderately eccentric so as not to cross the belt. It could still have high eccentricity if the outer belt was being fed with material from the outer belt though. Dinosaur-killing sized impacts would be frequent on any Earth-like planets, about once every 2 million years. One of 5 PICTURE-C targets selected for sub-orbital coronograph observation. One of the first 20 exoplanet systems allowed to be given common names by the IAU. Star is named after a Norse goddess of the seas, while the planet after her husband, god of the ocean. A common sci fi system, including the original home of Star Trek Vulcans (though this moved to 40 Eridani) and Babylon 5.
        • HIP 15689 System (3.9 ly; 14.3 ly) - The closest star to Epsilon Eridani and Keid, in Eridani. A dim red dwarf with an unconfirmed companion star or brown dwarf.
        • Teegarden's Star System (5.8 ly; 12.6 ly) - Teegarden's Star is also called SO 025300.5+165258 or SO 0253+1652 and informally Proxima Arietis. Nearby Red Dwarf star system with flares. It was found in 2003 by inspecting photographs used to discover near earth asteroids, whose motion can spot nearby stars with high proper motion. Only six other stars have a proper motion of more than 5 arcseconds per year.
        • LHS 1565 System (6.9 ly; 11.9 ly) - LHS 1565 is also known as L 372-58m, LTT 1702, GJ 1061 and informally called Proxima Horologii. Nearby Red Dwarf star system. Measurements in 1997 found it was a lot closer than it was once thought to be at 11.9 ly.
Keid Duchy[]
      • Keid System (10.1 ly; 16.5 ly) - Kied is also known as 40 Eridani, Omicron 2 Eri, and Gl 166. Triple star which is Gene Roddenberry's favored location for Spock's home planet of Vulcan. Consists of an Orange Dwarf primary A (also called HD 26965 and HR 1325) with a flare star Red Dwarf C (also called DY Eridani) orbiting 50 AU away, and a much further White Dwarf B at 600 AU. The white star would appear two orders of magnitude brighter than Venus does from any planets in AC, so it would be visible in the daylight. While no planet has been discovered in this system yet, it has been selected as a target for the SIM Planet quest when launched in 2015 for signs of a habitable planet. The White Dwarf is by far the easiest White Dwarf to observe, as it is brighter than the closer Van Manaan's Star and is not swamped by the light of a bright primary like those found in the Sirius or Procyon systems.
        • 2MASS 0415-0935 System (; 18.7, assumed) - 2MASS J04151954-0935066 is abbreviated as 2MASS 0415-0935. It is a nearby T-Class brown dwarf in Eridani. It was the coolest brown dwarf known when discovered in 2002.
        • LHS 1723 System (5.2 ly; 19.9 ly) - LHS 1723 is also known as LP 656-38 and NN 3323. Variable Red Dwarf star in Eridanus.
        • BD-03°1123 System (6.2 ly; 18.6 ly) - BD-03°1123 System is also called Wolf 1453 and Gl 205, and is located in Orion. With 57% of the Sun's mass, this is one of the larger Red Dwarf stars, sometimes classified as an Orange Dwarf. Mnemonic: BD Orionis.
        • LTT 17897 System (8.4 ly; 17.4 ly) - LTT 17897 is also called G 99-49 and NN 3379 and informally Proxima Orionis (located near Betelgeuse). Red Dwarf flare star. 163,000 years ago, it was 4.3 light years from the Solar System.
        • Giclas 99-44 System (9.23 ly; 20.9 ly) - G 99-44 is also called GJ 223.2, GJ 9193, LP 658-2, LHS 32. It is the 8th closest white dwarf star to the Sun and is in Orion.
        • BD-21°1377 System (9.77 ly; 18.9 ly) - BD-21°1377 is also called L 668-21 and Gl 229 and informally as Proxima Leporus. It is a red dwarf flare star (has one of the highest diameters) with a T6V brown dwarf orbiting it. It has 25 to 65 times Jupiter's and currently about 40 AU from the star. This was the first sub-stellar mass object discovered, in 1994. The star is the current Spectral Standard star for class M1 V.
BD+04°123 Duchy[]
      • BD+04°123 System (14.5 ly; 24.3 ly) - BD+04°123 is also called HR 222, Gl 33, HD 4628, and 96 G. Piscium. A relatively bright and nearby orange dwarf system visible to the naked eye. Mnemonic: BD Piscium.
        • Lalande 46650 System (7.5 ly; 19.56 ly) - Lalande 46650 is also called Gl 908 and BD+01°4774. Nearby M2 Red Dwarf flare star also called BR Piscis. Currently about 20 light years away, it will become twice as near in 63,000 years.
        • Gliese 1286 System (8.2 ly; 23.5 ly) - GJ 1286 is also known as G 157-77 and LHS 546. Nearby red dwarf star system in Pisces.

Rana Client Kingdom[]

  • Rana System (24.1 ly; 23.1 ly) - Rana is also known as Delta Eridani, HD 23249, HR 1136, and Gl 150. Nearby orange-red sub-giant star system about 30ly away. Has about 2.5 times the Sun's radius. Early estimates thought it could have 87% of the Sun's mass, but newer estimates suggest 1.2 times its mass. It is thought to have evolved from an F8 main sequence star 7.5 Billion Years ago. It will later become a true giant star. Astrometric observations suggest a companion star, but this has not been confirmed with radial velocity, perhaps because its effect would be small due to its inclination to the Sun.
    • Giclas 160-28 System (2.7 ly; 31.0 ly) - G 160-28 is also known as GJ 1065 and LHS 183. Nearby red dwarf system in Eridanus.
    • Luyten 730-18 B System (7.4 ly; 24.8 ly - figure disputed) - Double star in Eridanus. It is not clear if L 730-18 is an actual or just an apparent double star. Some sources list them as the same distance, while others at quite different distances. Star A is also known as LP 771-95, NN 3192 A, and HIP 14101 (?). Star B is also known as LP 771-96 and NN 3193 B. Some sources say they are separated by 48 AU, but it is not clear if this is the distance between A and B or if B itself is a binary with this distance.
BD-13°544 System Duchy[]
      • BD-13°544 System (10.3 ly; 33.9 ly) - BD-13°544 is also known as Gl 117, HIP 13402, HR 857, and HD 17925. Nearby orange dwarf star system in Eridanus. It is part of the Beta Pictoris moving group. A strong lithium presence indicates that it must be a very young star. Since it is at about 10 parsecs away, its absolute and apparent magnitude are about the same, which is at the very limit of human detection at magnitude 6.04. Mnemonic: BD Eridani.
        • Luyten 730-18 A System (3.1 ly; 35.2 ly - figure disputed) - Double star in Eridanus. It is not clear if L 730-18 is an actual or just an apparent double star. Some sources list them as the same distance, while others at quite different distances. Star A is also known as LP 771-95, NN 3192 A, and HIP 14101 (?). Star B is also known as LP 771-96 and NN 3193 B. Some sources say they are separated by 48 AU, but it is not clear if this is the distance between A and B or if B itself is a binary with this distance.

Kappa Ceti Principality[]

    • Kappa Ceti System (11.9 ly; 29.9 ly) - Kappa Ceti is also known as Kappa 1 Ceti, HD 20630, HR 996, and Gl 137. Nearby yellow dwarf star system. Kappa 2 Ceti is nearby it in the sky, but is a giant yellow star ten times as far away. Kappa Ceti has similar mass and size as the Sun, but is cooler and less bright. It is much younger than the Sun, at 800 Million Years old. It may emit superflares, which may make life impossible on any otherwise inhabitable worlds. Past spectroscopic studies suggested a partner star, but this has not been confirmed with radial velocity studies.
      • Giclas 77-31 System (2.5 ly; 27.7 ly) - G 77-31 is also known as GJ 1057 and LHS 168, NLTT 10256, and. Nearby red dwarf BY type variable star system known as CD Cetus.
      • Giclas 76-62 System (9.5 ly; 38.7 ly) - G 76-62 is also known as GJ 1055 and LHS 1504. Nearby red dwarf star system.
BD+06°398 Duchy[]
      • BD+06°398 System (8.3 ly; 28.2 ly) - BD+06°398 is also known as HR 753, HD 16160, and Gl 105. It is a triple star system comprising of an orange dwarf (A) and two red dwarf (B, C). Star A lies at the minimum mass needed for core fusion of Hydrogen. It's habitable zone would be centered at Mercury-like distances. B lies 1,200 AU away, and is a flare star and a BY Draconis variable star also known as BX Ceti. C is an extremely faint Red Dwarf and only about the size of Jupiter and is separated from A by 24 AU, but likely has extreme eccentricity (0.75). It is near the lower mass limit needed to sustain nuclear fusion. Hubble confirmed its existance in 1995. Mnemonic: BD Ceti.
        • LP 469-206 System (5.5 ly; 27.7 ly) - LP 469-206 is also known as NN 3146 and LHS 1376. It is Nearby red dwarf flare star in Aries.
        • LP 469-67 System (6.8 ly; 29.0 ly) - LP 469-67 is also known as NN 3128 and LHS 1326. Nearby red dwarf system in Pisces.

Tabit Client Kingdom[]

  • Tabit System (19.7 ly; 26.1 ly) - Tabit is also known as Pi3 Ori, Gl 178, HD 30652, and, HR 1543,. Nearby Yellow-White Main Sequence star. It is type F6, has about 1.3 times the Sun's mass, and the same amount of its radius. It has a stable spectrum, which is used to compare with other stars. It is the brightest star in Orion's "shield" or "lion". It has a companion star that may be visual or optical. It is now 26.2 ly away, but came within 15 ly 210,000 years ago.
    • Ross 41 System (5.1 ly; 28.4 ly) - Ross 41 is also known as Gl 203 and LHS 1761. It is a nearby red dwarf star system in Orion. It is now 29 ly away and was as close as 13.8 ly 111,000 years ago.
    • BD+18°683 System (7.5 ly; 30.3 ly) - BD+18°683 is also known as Gl 176. It is a nearby red dwarf with a low period neptunian in Taurus. It was likely first catalogued in the Bonn Survey published in 1863 and its high proper motion discovered by Ross. Planet is the fourth discovered Neptunian around a Red Dwarf star. Categorized as a gaseous Hot Superterran with a metals-rich atmosphere. Mnemonic: BD Taurus.
    • Ross 47 System (8.9 ly; 18.9 ly) - Ross 47 is also known as Gl 213 and V1352 Orionis. It is a nearby red dwarf star system located in Orion. Has frequent flares.

BD-05°1123 Duchy[]

      • BD-05°1123 System (6.6 ly; 28.7 ly) - BD-05°1123 is also known as Gl 183 and HR 1614. It is a nearby orange dwarf star system in Eridanus. It is the title member of the 2 Billion Year Old HR 1614 Moving Group. It is a spectroscopic binary, although no data is available on its companion star. Mnemonic: BD Eridani 2.
        • Luyten 879-14 System (4.3 ly; 31.0 ly) - L 879-14 is also known as NN 3306 and LHS 194. Nearby white dwarf system in Eridanus.

Chi 1 Orionis Principality[]

    • Chi 1 Orionis System (9.9 ly; 28.3 ly) - Chi 1 Orionis is also called Gl 222, HR 2047, and HD 39587. Nearby binary star system. A yellow dwarf star somewhat brighter than the Sun and a red dwarf. Because the red dwarf orbits 3.3 to 8.9 AU, the chances of a habitable planet are low. A member of the Ursa Major Moving Group. There is a theory that this star may have once been in a star system that includes HD 147513 A and B (which have a planet), which is part of the same moving group. When HD 147513 B went on to become a White Dwarf, material was sluffed off onto Chi 1 Orionis A, enriching it and causing it to become a "Barium Dwarf". Gravitational instabilities caused Chi 1 Orionis and HD 147513 systems to separate.

Procyon Client Kingdom[]

Has 2 Unconfirmed Planets

  • Procyon System - (5.1 ly; 11.4 ly) Procyon is also known as Alpha Canis Minoris, HD 61421, and HR 2943. Nearby Bright star system. Nearest yellow white star (F5 IV–V) to the Sun and the closest star to Sirius. It is the 7th brightest star in the sky. Has a white dwarf companion B. Has about 50% more mass than the Sun and about twice its radius. It is a BY-Draconis type of variable (unusual for a bright star) and entering the last stage of its life on the main sequence, heading towards a sub-giant, as its core seems to have exhausted its supply of Hydrogen and is starting to fuse Helium. Its habitable zone, which is 2 to 4 AU, may be disrupted by B, which is only 9 to 21 AU away. Star B was first predicted due to its effect on A's proper motion in 1844 and later spotted in 1896. It was probably about the same mass as Star A, and sterilized the system when it went into a giant phase. Luyten's Star is only 1.2 light years away, near enough to stir up any Oort clouds in either system and would be dimly visible.
    • Luyten's Star System (1.2 ly; 12.4 ly) - Nearby Red Dwarf star system also known as BD +05°1668 (sometimes called Luyten 5-1668) and Gl 273. It is in Canis Minor. Named after William Luyten, who with Edwin G. Ebbighausen, first determined its high proper motion in 1935. It is at the maximum mass that a star can be fully convective (ie, the entire star has a single convection zone). It is the closest star to Procyon (1.2 ly), which would appear as -4.5 magnitude star in any of its planets skies.
    • Ross 614 System (4.6 ly; 13.4 ly) - Ross 614 is also called Gl 234. A nearby binary Red Dwarf. Star A is the flare star known as Nearby V577 Monocerotis. First discovered by Ross in 1927 and then Star B was discovered in 1936. Star B has long been considered the quintisential low mass star. Unfortunately its long period of 16.6 years makes it difficult for most studies to observe. They're separated by 2.4 to 5.3 AU.
    • Giclas 51-15 System (5.0 ly 11.7 ly) - DX Cancri is also known as G 051-015, GJ 1111 and informally Proxima Cancri. It is a nearby red dwarf flare star designated. A "spectacular" flare was detected in 2006. A search for a dust disk was undertaken, but none was found. This is thought to be a member of the Castor Moving Group. Its proper motion may first have been noticed by William Luyten.
    • Giclas 41-14 System (5.3 ly; 22.1 ly) - G 41-14 is also known as LHS 6158, and LTT 12352, and NN 3522. It is a is a triple red dwarf system located 22.1 in Hydra, each which is an M4.5 star. A and B are separated only by 0.05 AU. C orbits at 4.5 AU. Older data prior to the resolution of the tightly coupled AB lists it as a single Orange dwarf system.
    • Giclas 9-38 System (8.0 ly; 17.0 ly) - Giclas 9-38 is also known as GJ 1116. It is a binary Red Dwarf separated by 23.5 AU. Star A is a flare star designated EI Cancri. Star B is very tiny and also flares. A SETI signal was detected from this star in 1997.
    • Ross 882 System (8.0 ly; 19.3 ly) - Ross 882 is also known as Gl 285. It is a nearby binary Red Dwarf star. One of the stars is a flare star dubbed YZ Canis Minoris.
    • HIP 33226 System (9.9 ly; 17.9 ly) - Wolf 294 is also known as AC +33°25644, Gl 251, HIP 33226, and informally as Proxima Geminorum. It is a nearby red dwarf star. (note HIP 33226 may be a separate object?)
    • Gliese 251 System (10.8 ly; 18.9 ly) - Wolf 294 is also known as AC +33°25644, Gl 251, HIP 33226, and informally as Proxima Geminorum. It is a nearby red dwarf star. (note HIP 33226 may be a separate object?)

Groombridge 1618 Duchy[]
      • Groombridge 1618 System (12.9 ly; 16.0 ly) - Groombridge 1618 is also known as Gl 380 and HD 88230. Nearby orange dwarf system in Ursa Major. It is an unusually bright flare star, but flares less frequently than other such stars. Its level of activity suggests it is relatively young, perhaps a little older than a Billion years. First identified in A Catalog of Circumpolar Stars by Stephen Groombridge, published posthumously in 1838. An unconfirmed planet was published in 1989 with 4 Jupiter masses at about half Earth's distance, in the inner part of the star's habitability zone. It's signal could be due to stellar activity. Its closest neighbor is a red dwarf UX UMa, which would flicker in and out of visibility due to the effects of its flares.
        • Lalande 21258 System (3.2 ly, 15.6 ly) - Lalande 21258 is also known as Gl 412. It is a nearby binary red dwarf star, sharing a common motion in the sky. The secondary star is a flare star (identified in 1939) also known as WX Ursa Majoris and has been identified as a major source of x-rays. The stars are far enough apart (190 AU) that any planets around star A would be unaffected by the flares from Star B. It would be visible during flare episodes from its nearest neighbor Groombridge 1618. They are members of the Halo population of the galaxy.
        • Lalande 21185 System (8.0 ly, 8.1 ly) - Lalande 21185 is also called GJ 411 and informally Proxima Ursa Majoris. It is the fourth closest star system to the Sun at 8.3 ly. It is the third brightest red dwarf in the night sky. It has been the spectral standard star for class M2 V for a long time. It is sometimes classified as a BY Draconis type variable star and has been known to emit x-rays. Van de Kamp thought he found planets in 1951. The system has two unconfirmed planets detected via radial velocity in 1996. It is also one of the earliest planets detected that still has a good chance to exist. The planets orbit far away from their dim Red Dwarf star, which makes one planet colder than Saturn and the other colder than Neptune despite being at a Saturn-like distance. One confirmed planet is a hot super earth with a rocky surface. The star is the nearest Galactic 'Thick Disk' star (which includes about 4% of nearby stars), and moves perpendicular to the galactic plane. It will get nearest to the Sun in 19,000 years when it is 4.65 ly.
        • BD+20°2465 System (8.1 ly, 16.0 ly) - BD+20°2465 is also known as Gl 388. It is a nearby red dwarf flare star also known as AD Leonis and one of the better studied flare stars. It was suspected of having a planet or Brown Dwarf in 1949, but this has not been confirmed.
        • AC+23°468-46 System (10.8 ly, 21.5 ly) - AC+23°468-46 is also known as Gl 408. Nearby red dwarf star in Leo.
        • Wolf 424 System (12.6 ly, 14.1 ly) - Wolf 424 is also known as Gliese 473. Nearby binary Red Dwarf separated by about 2.36 to 4.19 AU with a period of 16.2 years. The secondary star is a flare star known as FL Virginis. At one point, it was thought that these could be high massed Brown Dwarves, but this has been disproven.
        • Wolf 358 System (12.9 ly, 22.5 ly) - Wolf 358 is also known as Gl 402. It is a nearby red dwarf star, possibly with a companion. It is also a flare star called EE Leonis. It is the M4 V spectral standard star.

Altair Kingdom[]

Has no known planets

  • Altair System (*16.7 ly) - Altair is also called Alpha Aquilae, GJ 768, HD 187642, and HR 7557. Second nearest A main sequence class star, on the verge of becoming a sub-giant, and about 1 Billion years old. One of the stars of the Summer Triangle and 12 brightest star in the sky. It is a particularly rapidly spinning (9 hours) and flattened (20%) star. It has 1.7 the Sun's mass and 1.8 its diameter. Its brightness fluxuates slightly, classifying it as a Delta Scuti variable star and given a New Suspected Variable star designation of NSV 24910. In 2006, it became the first star to be directly imaged (in the infrared) other than the Sun. Its equator is darker than its pole due to its rapid rotation, which was visible as a white spot in images. No planets have been detected and there are some theoretical reasons for why a star rotating so quickly might not have planets. It has two visual companions that are not bound to it, but merely close to it in the sky. One of 5 PICTURE-C targets selected for sub-orbital coronograph observation.
    • Wolf 1055 System (3.6 ly; 19.2 ly) - BD+04°4048 is most commonly known as Gliese 752 and also called DM+04°4048. A nearby binary Red Dwarf star system in Aquila and the nearest star to Altair, which appears two order of magnitude than in our sky. Star A is also a flare star known as V1428 Aquilae and is also known as HD 180617. Its high proper motion was first noticed by Max Wolf in 1919, and dubbed Wolf 1055. It was later rediscovered by Frank Ross in 1927 and dubbed Ross 652. It has about half of the Sun's mass and radius and is the M3 V spectral standard star. Star B is also a UV Ceti variable star known as V1298 Aquilae and VB 10 or simply Van Biesbroeck's Star. It shares a proper motion with star A, but is not gravitationally bound with it and lies 434 AU away. VB 10 was the faintest star known when it was discovered in 1944 and is the M8 V spectral standard star. VB 10 contains a controversial "first" exoplanetary system announced in 2009 using astrometry and lies only 20 light years away, but not confirmed with dopplar spectrometry. Would be smallest known star to host a planet and is a flare star. Contain's a cold Jupiter six times Jupiter's mass a Mercury like distance. The "planet" and the star are about the same size and the planet contains 10% of the mass of the system. The star will burn for 10 trillion years, then the planet would fall into it, fuelling it for another 100 billion years. The system is about 1 Billion years old. Mnemonic is BD Aquilae.
    • AC+17°534-105 System (9.8 ly; 21.8 ly) - AC+17°534-105 is most commonly known as Gl 829, but also as R 775, G 126-4. It is a binary red dwarf star system in Pegasus. Star A is also known as LHS 508. Both stars have the same spectral type M3.5.
    • Gliese 791.2 System (12.1 ly; 28.6 ly) - Gl 791.2 is also known as G 144-8, LHS 3556, and HU Delphini. It is a red dwarf flare star with a companion star. Their paralaxes were measured by the Hubble Space Telescope. Their masses are particularly well known, with A being 28% (M6 V) that of the sun and B at 12% of the Sun, and they help define the characteristics of low-mass stars. This helps study brown dwarfs, which are only slightly less massive.
70 Ophiuchi Duchy[]
    • 70 Ophiuchi System (7.8 ly; 16.6 ly) - 70 Ophiuchi is also known as GJ 702 and HD 165341. It is a nearby pair of orange dwarves, easily visible with the naked eye when away from city lights. Star A is a DY Draconis variable star and is also known as HR 6752. It was first cataloged by William Herschel in the late 18th century during his study of binary stars, who claimed Father Meyor noticed its duplicity earlier (whose other claims could not be verified by contemporaries). He proved the two stars went around each other, an important verification of Newton's laws. He suspected another object was affecting the orbits of the two stars. Other astronomers claimed this could be a planet, such as Captain Jacob in 1855, which is one of the first claims for a planet using astrometric data. See also made a claim in 1899, but Moulton soon published a paper showing that this system would be unstable. In 1943, Reuyl again caused a sensation by claiming planets, only to be refuted again. The two stars follow an eccentric orbit ranging from 11.7 to 34.8 AU away. Star A has about 92% of the Sun's mass. The stars are thought to be 1.5 Billion Years old.
      • BD+24°3192 System (3.2 ly; 10.4 ly - based on inaccurate Hipparcos data) - BD+24°3192 is also known as HIP 85605 and CCDM J17296+2439. Nearby binary star system in Hercules, an Orange Dwarf star with a star of unknown spectral type (HIP 85605). The Hipparcos catalog gives HIP 85605 a nearby distance of 16 ly, which is likely inaccurate, as it doesn't match that of CCDM J17296+2439.
61 Cygni Duchy[]
    • 61 Cygni System (9.8 ly; 11.41 ly) - 61 Cygni is also called Gl 820, very rarely called Bessel's Star, and informally Proxima Cygni. Nearby star system containing two orange dwarves. This was the star with the highest proper motion known in the 1830s and dubbed as "The Flying Star" by Giuseppe Piazzi in 1792. It is the star with the highest proper motion of any stars visible with the naked eye. In 1911, it was found by Boss to be a part of a moving group, dubbed the 61 Cygni Moving Group. Friedrich Struve first made measurements of it as a binary system in 1830. It was also the first system to have its distance measured by parallax, which was done by Bessel in 1838. The stars are barely visible with the naked eye. The stars are separated on average by 86 AU. The stars atmospheres likely do not touch. The stars are old, 6 to 10 Billion Years old. There were several claims of a planetary system in the 20th Century, but none have panned out. This includes Strand's claim in 1942 (under the direction of Van de Kamp), and Soviet claims in 1977. Heintz proved in 1978 that these claims were false. Due to its proximity to Earth, the star was a tier 1 priority for the Space Interferometry Mission, which hoped to discover planets.
      • Kruger 60 System (5.2 ly; 13.0 ly) - Kruger 60 is also known as BD +56°2783 and Gl 860. It is a nearby pair of Red Dwarfs. B is a flare star known as DO Cephei, which would probably prevent life from developing on any planets. Their distances vary from 5.5 to 13.5 AU. B would appear as a point as bright as the full moon from A. In 88,600 years, it will come closest to the Sun at 6.4 light years, compared to its present distance of 13.1 ly.
      • V1581 Cygni System (5.2 ly; 15.3 ly) - V1581 Cygni is also known as GJ 1245. Nearby triple Red Dwarf star system. Star A is only 11% the Sun's mass and is also known as G 208-44 A and LHS 3494. C is 8 AU (7% Sun's Mass) from A and is also known as G 208-44 B. It is one of the more well known tenuous red dwarfs and is only an M8 in spectral type. B is 33 AU away (10% Sun's Mass) and is also known as G 208-45 and LHS 3495. B would appear as bright as Venus does from A.
      • Ross 248 System (5.5 ly; 10.4 ly) - Ross 248 is also called Gl 905 and informally Proxima Andromedae. Nearby Red Dwarf flare star system dubbed HH Andromedae. There are indications of perterbations caused by an unseen companion, but searches for a brown dwarf star failed to find anything. It will become the nearest star to the sun in 33,000 years. Voyager 1 is heading in the direction of Ross 248 and is expected to be 1.76 light years from it in 40,176 years. It is currently very close to Groombridge 34, which is only 1.8 light years away, and could be visible from that star.
      • Struve 2398 System (6.1 ly; 11.4 ly) - Struve 2398 is also called Sigma 2398, BD+59°1915, DM+59°1915, and Gl 725, and informally Proxima Draconis. It is a nearby binary red dwarf system. The distance of the two component stars was first measured by Friedrich von Struve in 1832. Star A is also known as HD 173739. It is inaccurarely referred to as a K type star in some catalogs. Star B is also known as HD 173740. Their distance ranges from 19 to 65 AU. An observer from Star A would see Star B as a point about as bright as the full moon.
      • Groombridge 34 System (7.1 ly; 11.7 ly) - Groombridge 34 is also known as Gliese 15 and HD 1326. It is a double red dwarf star. Both are flare stars, with A being dubbed GX Andromedae and B GQ Andromedae. The stars are 147 AU apart in nearly circular orbits. Ross 248 is only 1.8 light years away. Currently the closest known multi-exoplanetary system.

Fomalhaut Kingdom[]

13 Known Planets in 8 Systems

  • [1] Fomalhaut System (*25.1 ly) - Fomalhaut is also known as Piscis Austrini, 24 Piscis Austrini, Gl 881, HD 216956, and HR 8728. A triple star, the second brightest star known to have exoplanets. Star A is a white main sequence star about twice the Sun's mass and somewhat less than twice its radius. It was originally thought to be about 200 million years old, but now thought to be 400 MYO, and will turn into a giant in about a billion years. Its dust disk is observed in unprecedented detail. It appears reminiscent of the "Eye of Sauron" from the Lord of the Rings films. A planet suspected of causing a sharp gap in the ring was suspected and imaged, becoming the first visually detected and the first planet since Neptune to be predicted prior to its discovery. The planet, Dagon, orbits about 115 AU and is between Neptune and 3x Jupiter's mass in an eccentric orbit. Planet b was shown to deviate slightly from its predicted path, stirring up some controversy about the planets' existence. The Hubble instrument that detected it is damaged and will not be fixed, making it unobservable for a time. Later analysis of old Hubble data confirmed its existence. Material surrounding the planet has been imaged, rather than the planet itself, which its discoverers admit takes it off the directly imaged list. The planet is hurdling outward from the star in a highly elongated path and will encounter the inner edge of the outer belt in 2032, where icy debris will smash into its atmosphere (unless its orbit is highly inclined). No heat has been detected from the planet, which suggests it is sub-Jovian in mass and could be as small as Pluto, though this could be explained by dissipation from surrounding dust. Evidence for another planet "slicing" through the dust disk was also found, and it may have been responsible for planet b's elliptical orbit. The shape of the ring was put into focus by ALMA, 140 AU out, 16 AU wide, and 1/7th AU thick, placing limits on proposed shepherding exoplanets and showing them to be quite small (a couple times larger than Mars), perhaps why they weren't detected visually. Mapping by ALMA was completed later on and shows the first "apocenter glow", where dust particles clump around slower moving and further out parts of their elliptical orbit. Some proposed inner planets via effects of debris disk could be better interpreted as gas produced effects. The ring is believed to be continuously replenished by cometary collisions occurring every day. An estimated 260 Billion to 83 Trillion comets could exist in it, equivalent to what is in the Sun's Oort Cloud. Star B, an orange dwarf 0.91 ly away has no known disk. Star C, a recently identified Red Dwarf member of the system, located extremely far from the primary (2.5 ly), was also found to have its own disk. Previous interactions may have tilted Star A's disk. The star is a part of the Castor Moving Group. One of the first 20 exoplanet systems allowed to be given common names by the IAU. The planet is named after a half fish Semitic god.

0 Known Planets

  • TW Piscis Austrini System (0.73 ly; 24.7 ly) - TW PsA is also known as Gl 879, HR 8721, HD 216803, and CD-32°17321. An orange dwarf flare star and a BY Draconis variable, one of the larger such stars. Less than a light year from Fomalhaut (57,000 AU), and possibly gravitationally bound to it in a cluster or stellar association in the Castor Moving Group. They were found to share a common proper motion and in 2012 it was found to be consistent with a binary syste. About 200 Million Years old, along with the rest of the group. Visible to some humans with the naked eye.
    • HIP 114176 System (3.0 ly; 22.1 ly - does not exist) - Fictitious nearby red dwarf. It does not exist, as the Hipparcos satellite actually only detected scattered light from a nearby star (HIP 114177).
    • Luyten 362-81 System (7.6 ly; 25.4 ly) - L 362-81 is also known as Gl 915 and LHS 1005. Nearby white dwarf in Phoenix. It is possibly the 11th closest white dwarf.

    • LP 881-64 System (8.2 ly; 20.9 ly) - LP 881-64 is most commonly known as LHS 1070 and also as GJ 2005. Nearby mid-M red dwarf with two brown dwarf companions in Sculptor. System was first found to be within 10 parsecs in 1986. Brown dwarfs B and C were discovered in 1994 as part of a duplicity survey of nearby red dwarves, but were at first thought to be very low mass red dwarfs. They orbit around each other about once every 16 years, while they go around star A once every 60 to 1000 years. They were thought to be a useful testbed for atmospheres of late main sequence stars, so determining their masses was important. They were confirmed to be early L type brown dwarfs in 2012. Star D was discovered in 1999, but mass for it is undetermined, possibly because of its close separation, but also the star might not actually exist.
    • Luyten 362-29 System (10.1 ly; 20.9 ly) - L 362-29 is also known as GJ 1001 and LHS 102 in Phoenix. Nearby red dwarf with two brown dwarf companions. B found to be a binary brown dwarf in 2003. C may have been the least massive measured L type brown dwarf when measured in 2006.

An active flare star and about 12 Million Years old. First red dwarf found with a circumstellar disk and the nearest planetforming disk. Also the first system where particle size in disk determined. Constraints on where planets could exist was recently published. Patterns in the dust disks suggest planets. It is thought that Pluto-sized planetoids may have formed in the outer system. AT MiC A and B are separated by 24.2 to 40.8 AU, and are somewhat smaller than AU MiC. All components are part of the Beta Pictoris Moving Group.

It is one of the least variable stars observed during the Hipparcos mission. Its similarity to the Sun make it an interesting target. It is about 3 Billion Years old. It is thought to have a debris disk. Its rotational velocity appears to be almost zero, indicating it presents its pole towards us, which would make finding planets through radial velocity nearly impossible.
        • CD-68°47 System (3.3 ly; 26 ly) - CD-68°47 is also known as Gl 54. Nearby binary red dwarf system. Star A is sometimes given a spectral class K.

Delta Pavonis Principality[]

3 Known Planets around 2 Planetary Systems; 3 Unconfirmed Planets

    • Delta Pavonis System (9.3 ly; 19.9 ly)- Delta Pavonis is also known as Gl 780, HD 190248, and HR 7665. One of the nearest bright stars to the sun. Although somewhat smaller than the Sun, it is easily visible with the naked eye. It is about 6.8 Billion Years old. It has a New Suspected Variable designation NSV 12790 and appears unusually bright for a main sequence star, so may be starting to become a sub-giant. It was identified as the best SETI target of the nearest 100 G-type stars. It is the nearest solar-analog in a single system and is type G5-8 V-IV.
      • Luyten 119-44 System (5.9 ly; 22.2 ly) - L 119-44 is also known as GJ 4285 and LTT 91087. Nearby red dwarf star of spectral type M 3.5 and nearest star to Delta Pavonis.
      • Luyten 205-128 System (6.2 ly; 18.9 ly) - L 205-128 is also known as Gl 693. Nearby red dwarf in Pavo. It is a variable star also known as NSV 9629 and CSV 102836.
      • HIP 82725 System (7.6 ly; 15.9 ly; likely error) - HIP 82725 and HIP 82724 were thought to be a nearby binary system in Ara. Some sources indicate these are two red dwarfs. Others suggest this HIP 82725 is an orange subgiant star and HIP 82724 is a dwarf star and that the parallax measurement of Hipparcos is wrong.
Epsilon Indi Duchy[]

0 Known Planets

      • Epsilon Indi System (9.3 ly; 11.7 ly) - Epsilon Indi is the also known as HR 8387, Gl 845, and HD 209100. Second nearest single sunlike star to the Sun. Orange dwarf with a binary brown dwarf orbiting it. The smaller of the two is the closest thing to an "extrasolar moon" found so far. The constellation "Indus" first appeared in 1603 in the Uranometria. Epsilon Indi appeared as one of the Indian's arrows in Bode's 1801 atlas, the Uranographia. The star's high proper motion was first discovered by Gill in 1882, which was improved upon by Shapley in 1923. During 1960, the star was observed for radio signals, but none was found. In 1972, it was searched for ultraviolet laser signals. It leads a Carnegie list of stars most likely to have an earth-like planet. The star's age has been controversial, at first thought to be older than the sun, then younger, then even older than originally thought, all based on studies regarding the brown dwarf's nature and the rotation rate of the star.
        • Lacaille 8760 System (4.4 ly; 12.7 ly) - Lacaille 8760 is also known as Gl 825 and informally Proxima Microscopii. Considered the brightest red dwarf in the sky, though it is sometimes listed with a K spectral type. It is just barely possible for someone with exceptionally good eyesight to see under the ideal conditions. Its orbit is rather tilted and eccentric. Its high proper motion was first noticed by Carl Moestra in 1875. It is a variable star known as AX Microscopii, but does not have devastating flares which would disrupt life. The habitable zone would be from 0.27 to 0.53 AU.
        • Lacaille 9352 System (4.7 ly; 10.8 ly) - Lacaille 9352 is also called Gl 887 and HD 217987 and informally Proxima Piscis Austrini. Nearby red dwarf star with about half the sun's mass and radius. It is the second bright red dwarf in the sky, but is too dim to see unaided. Its high proper motion was discovered by Gould.
        • CD-49°13515 System (4.8 ly; 16.0 ly) - CD-49°13515 is most commonly known as Gl 832, and also L 354-89, DM-49°13515, and HD 204961. It is the third nearest red dwarf with planets and in the constellation Indus. It can be considered a miniature version of the Solar System, with a large gaseous planet in a far orbit, and a smaller potentially rocky planet interior. Has a slightly eccentric Jovian planet with 64% Jupiter's mass at an asteroid-belt like distance. The planet has the second largest angular separation from it star of any known planets and is further from its star than any other red dwarf orbiting planet. A good astrometry detection candidate and a target for SIM. One of the larger red dwarf planets around one of the larger (M1.5) red dwarves (about half a Solar Mass). It also emits x-rays. Super Earth planet c is the most Earth-like known exoplanet, and one of the top three potentially habitable planets, but is more likely a super Venus. A third Earth-sized planet could exist between these planets.
        • Cincinnati System (6.7 ly; 14.0 ly) - Cincinnati is also known as HD 225213 and CD-37°15492. It is a red dwarf in Sculptor. It is a BY Draconis variable with the designation NSV 15017. Because it lies very close to the origin of the right ascension of the 1950 Epoch and thus became ordered as number 1 in both the Gliese Catalog of Nearby Stars (Gl 1) and the Luyten Half Second catalog (LHS 1). It is considered a "runaway star" and may be associated with the Tucana-Horologium and/or the AB Doradus stellar associations.
        • EZ Aquarii System (8.4 ly; 11.1 ly) - EZ Aquarii is also called Gl 866, L 789-6, and informally Proxima Aquarii. Nearby triple red dwarf star system, all near the lower limit of hydrogen burning of 75 Jupiters. All three put together is about a third of the Sun's mass. A (M5Ve) is only 11% as massive as the sun and 15% its diameter. Its high proper motion was first discovered by Luyten. A and B are in an eccentric orbit separated by 1.2 AU on average. A also has a spectroscopic binary companion C which has a period of only 3.8 days. C is so small that it's possible that it's a brown dwarf, though probably not. The stars are close enough to interfere with each other's habitable zones. It's possible a habitable planet exists around B, but flares would make this difficult.
J. Herschel 5173 Duchy[]

0 Known Planets

      • J. Herschel 5173 System (10.4 ly; 19.9 ly) - J. Herschel 5173 is also known as Gl 783, HD 191408, HR 7703, CD-36°13940, DM-36°13940, and 279 G. Sagittarii. Nearby orange dwarf star with a red dwarf companion, currently separated by 43 AU. Herschel first published it as a binary star. It is heading towards the Sun and will be 6.7 ly away (compared to its current 19.9 ly) in 40,000 and will be 10 times as bright. It could be a member of the Old Disk, which implies an age of up to 10 Billion Years old, though rotational analysis suggests 6.4 to 7.7 BY. It is a tier 1 priority for searching for planetary companions by SIM. Has two optical companions which are not optically bound, which are themselves binaries, Gl 783.1 AB Gl 738.2 AB.
        • CD-45°13677 System (3.4 ly; 20.2 ly) - CD-45°13677 is also known as Gl 784 and HD 191849. Nearby red dwarf star system in Telescopium.

It was the nearest star newly found to be nearby by Hipparcos in 1996 (17.9 ly, whereas all other newly identified stars were beyone 10 parsecs).
        • HIP 93449 System (8.9 ly; 26.7 ly - parallax error) - R Coronae Australis is also known as HIP 93449. It is a white giant star system surrounded by dust. Hipparcos inaccurately placed it at about 30 light years away, while Earth based parallaxes suggest a more likely 500 light years.
MLO 4 Duchy[]

2 Known Planets, 3 Unconfirmed Planets; 1 Known Planetary System

      • [2+] MLO 4 System (14.8 ly, 22.8 ly) - MLO 4 is most commonly known as Gliese 667 and also known as HR 6426 and HD 156384. A triple star system 23 light years away that contains planets in Scorpius. It was first cataloged as a binary star by astronomers at the old Melbourne Observatory (MLO) in Australia in 1867, so it was cataloged as MLO 4. It consisting of binary of orange dwarf stars about 12 AU apart (ranging from 5 to 20 AU), around which a distant red Dwarf C orbits (ranging from 56 to 215 AU). Star C is a dynamically packed planetary system, with at up to 7 unconfirmed super-Earth planets. The system became the nearest multistar system with planets when planet b (innermost, largest), a temperate super Earth planet (5.7 ME, 0.05 AU) was discovered, and is at the very inner edge of the most generous habitable zone. It became the poster child for an announcement of 32 exoplanets discovered by European astronomers working on the HARPs project and brought the total number of exoplanets to near 400. Planet c was later discovered near the inner edge of least generous habitable zone and is about the same size, and receives the same amount of stellar energy as the Earth. It was calculated that it likely no longer has a magnetic field that could protect its oceans from stellar radiation. Planets f and e were confirmed and also orbit in the Hz further out. Planet d is just beyond he HZ. Outermost planet, g (2.4 ME) is likely a frozen planet and the only one beyond Mercury-like distances. The multi-planet solution is somewhat lax and complicated and may need further confirmation. An even more unconfirmed planet h may be between b and c. A fourth stellar companion D is not gravitationally bound to the system.
        • CD-37°10765 System (7.0 ly, 27.7 ly) - CD-37°10765 is also known as Gl 618 and HIP 80018. Nearby binary red dwarf star in Scorpius, separated by 48 AU. Both stars are possibly sub-dwarf stars (A is M2-4 V-VI, B is M5.5 V-VI).
36 Ophiuchi Duchy[]

1 Known Planet

      • 36 Ophiuchi System (15.8 ly; 19.6 ly) - 36 Ophiuchi is also known as Gl 663. A nearby triple orange dwarf star system. Stars A and B have extremely eccentric orbits and their distance varies from 7 to 169 AU and are bright K0/K1 stars. Star A is also called HR 6402 and 155886, while Star B is also called HR 6401 and HD 155885. Limits have been placed on planets in this system and orbits beyond 1.5 AU may not be possible. Gliese Star C lies 5,000 AU away and is a dimmer star. It is also known as Gl 663C and Gl 664 and HD 156026. It is a RS CVn type variable star designated V2215 Oph. The system is relatively young at 1 to 1.8 Billion Years old and A is sometimes listed as a pre-main sequence star.
        • CD-32°13297 System (3.1 ly; 20.2 ly) - CD-32°13297 is also known as GJ 2130. Nearby triple red dwarf system in Scorpius. Star A is also known as HIP 86961. Star B is also known as HIP 86963 and CD-32°13298. A third star of unknown spectral type also exists. Some sources list its distance as 20.1 ly, while others 46.2 ly.
        • CD-44°11909 System (6.3 ly; 16.3 ly) - CD-44°11909 is also known as Gl 682 and DM-44°11909. Nearby red dwarf system in Scorpius, possibly a sub-dwarf (spectrum M3.5-4.5 V-IV).
        • BD-08°4352 System (6.3 ly; 18.6 ly) - BD-08°4352 is also known as Wolf 630, Gl 644, and HD 152751. It is a nearby triple or quadruple (once thought to be quintuple, and the nearest one) red dwarf system in Ophiuchus, consisting of Gl 644 A, Bb, Bc, C. It is also known as Gl 644. All stars are red dwarfs, but combined exceed the Sun's mass. Stars A and B (Ba/Bb) are separated by about 1.3 AU, which for 50 years was the closest any stars have been visually resolved since its duplicity was found in 1934. These three stars are probably coplanar. Star A is the flare star known as V1054 Ophiuchi. Star B is a close unresolved spectroscopic binary, with Ba and Bb being separated only by 0.04 AU (but it might just be a single star). Star C orbits at 1420 AU away, though stability analysis suggests it must be at least 2840 AU. It is flare star and also known as VB 8 and is the smallest and faintest member. VB 8 is the M7 V spectral standard star. In 1984, there were claims that the first exoplanet orbited this star, and later claims of a Brown Dwarf, but these have been refuted. It was once thought that Wolf 629 was gravitationally bound to this system, which was also dubbed planet D. Parallax measurements showed that it has to be at least 1 ly from the system though. The star is the first star in the proposed Wolf 630 moving group.

It is one of the dimmer yellow dwarf stars. Has three radial velocity detected super Earth planets orbiting closer than the habitable zone. The outermost one d is the largest (5 times Earth's mass, twice its radius, rocky-water composition) is about the same distance as Mercury is from the Sun. The middle one c is 0.1 au closer and is the smallest (2.5 Earth's mass, 1.5 its radius) and is likely a rocky-iron in composition. The innermost one is at 0.1 AU and just slightly larger than c, but more massive and of a more rocky-water composition. A dust disk was also found about 20AU from the star. The 2007 book "Habitable Planets for Man", released prior to the discovery of the planetary system, placed this as the most habitable star system within reach of mankind.

Contains the first exo-planet around a normal star discovered and the first "Hot Jupiter" found, which is nicknamed "Bellerophon", and now called Dimidium. Star is about 50 ly located in the square of Pegasus, a G5 star somewhat larger and more massive than the Sun. The planet's discovery was incompatible with planetary system formation models, so they were tweaked to allow for planetary migration. It was also initially thought to be an anomaly or the stripped down core of a brown dwarf. Found to have supersonic winds that caused the eternal night-side hemisphere to be as hot as the day-side one. During its 20th anniversary, this planet became the first one's whose reflected visible light was detected. The technique involved looking at a star's visible spectrum, and then detecting a faint reflection of this spectra. Its actual mass (0.46 MJ) and inclination (9deg) were obtained as a result. The planet seems to have a larger radius and bright surface, rather typical for hot jupiters. One of the first 20 exoplanet systems allowed to be given common names by the IAU. The star's name is Latin for a Celtic tribe that lived in Switzerland (the place where its planet was discovered) during the middle ages. The planet's name is Latin for "half" due to the fact its minimum mass is half as massive as Jupiter's.

Vega Kingdom[]

1 Known Planet

  • Vega System (; 25.4 ly) - Vega is also known as Alpha Lyrae, HR 7001, HD 172167, and Gl 721. It is the fifth brightest star in the night sky the second brightest star visible from the Northern hemisphere, and brightest star in the Northern Summer. It is part of the Summer Triangle. It was the first star to be photographed in 1850. It is a slightly bluish star (A0) with about 2.15 times the sun's mass and 2.7 its diameter. It was at first estimated to be about 200 Million Years old, but now thought to be closer to 700. It was found to be rotating so fast that the equator bulges significantly (23%) and is cooler at its poles. Nearby star with one of the first detected circumstellar disks. The star is pointed nearly pole-on from the Earth, so it is ideal for the observation of dust disks. There have been many studies suggesting planets are responsible for features found in the disk. Two bright "clumps" of dust were identified and thought to be due to the gravitational effects of an eccentric planet's orbit. It was surmised that this disk was caused by a collision between Pluto sized objects. A distinct asteroid belt and kuiper belt at distance scales that dwarf our Solar Systems was found to exist, which suggest outer planets clearing out the space in between. These planets cannot be detected at the present, but could be detected by the James Webb Space Telescope. One of 5 PICTURE-C targets selected for sub-orbital coronograph observation.

    • Alsafi System (8.2 ly; 18.9 ly) - Alsafi is also known as Sigma Draconis, HR 7462, Gl 764, and HD 185144. It's name is from derived from Arabic for a "cooking tripod" that nomads used. It has been reclassified in 2003 as a G9 Yellow Dwarf star (it was thought to be an orange dwarf). It has about 90% of the Sun's mass and 80% of its diameter. There appears to be a sunspot cycle, though its length is undetermined, and it was found to be the least variable of any of the stars observed by Hipparcos. It is thought to be 7 to 8 Billion Years old. It was a tier 1 target for Nasa's Terrestrial Planet Finder and a top target for ESA's Darwin project before both projects were put on indefinite hold. It was described as being the fourth easiest star to find terrestrial planets. No indication of any planets or dust disks have so far been detected. One of 5 PICTURE-C targets selected for sub-orbital coronograph observation.

        • AC+56°1646-56 System (9.5 ly; 21.5 ly) - AC+56°1646-56 is also known as G 202-48 and Gl 625. Nearby red dwarf in Draco. It was suspected of being a possible binary in 1977.

Archird Principality[]

    • Archird System (16.1 ly; 19.6 ly) - Archird is also known as Eta Cassiopeiae and Gliese 34. Nearby yellow dwarf star (A) orbited by an orange dwarf star (B). It is the brightest star near the lines formed by the "W" of the constellation. Star A is also known as HR 219, LHS 123, and HD 4614, while Star B is also known as LHS 122. Star A is about the same size, mass, and age as the Sun, but only about 65% as metal rich. It represents what the Sun might look like from Archird. Its habitable zone is centered on 1.35 AU. At one time, Star A was thought to have a spectroscopic binary companion with a nine day orbit period. Star B may have first been discovered by William Hershel in 1779 two years prior to discovering Uranus, while he was seeking nearby double stars for parallax studies. Star B ranges from 36 to 107 AU. It has 56% of the Sun's mass and 66% it diameter, but only 3% its luminosity. Radial velocity variations have been detected, though no planet has been announced at this time. The system is a top tier target for TPF. In Star Trek, this is home to Terra Nova.
        • Stein 2051 System (9.1 ly; 17.9 ly) - Stein 2051 is also called Gl 169.1. It is a binary star system consisting of a Red Dwarf (A) and a White Dwarf (B) separated by 39 AU in Camelopardalis. It is the nearest system of this configuration. Star A is the brighter of the two stars, but B is the more massive. Star A is also known as LHS 26. A vast asteroid belt exists around Star A at 2 AU. A small companion, probably a brown dwarf, but possibly small red dwarf, orbits Star A further out at 4.8 AU. Star B is also called G 175-34 and LHS 27.

BD+56°2966 Duchy[]

      • BD+56°2966 System (4.9 ly; 21.2 ly) - BD+56°2966 is also known as Gl 892, HR 8832, and HD 219134. Nearby orange dwarf star and flare star. Its habitable zone is centered at 0.46 AU. It was a top tier target for the Terrestrial Planet Finder and Darwin missions. It might have a red dwarf companion.
        • BD+43°4305 System (6.4 ly; 16.3 ly) - BD+43°4305 is also known as Gl 873 and informally as Proxima Lacertae. It is a very active and well observed flare star known as EV Lacertae. It was observed by the SWIFT satellite emitting the largest flare observed in the solar neighborhood in 2008. It was the brightest as seen from Earth around any star other than the Sun and would have made the star visible to the naked eye for one to two hours. Such a flare would strip the atmosphere off of a life bearing planet. This offered proof that the star was indeed young and had a much stronger magnetic field than the Sun. Magnetic double layers from this star probably extend for thousands of light years. The star has 28% of the Sun's mass, 38% of its radius, and is normally a magnitude 11.7 star. The rotates in only 4.4 days and is about 100 mllion years old. It is covered in dark star spots. In the 1970's and 80's, it was suggested that some of the flare activity could be explained by a further out red dwarf or brown dwarf companion exists in a 45 year orbit. This has not been confirmed.

Rutilicus Client Kingdom[]

1 Known Planet

  • Rutilicus System (16.1 ly; 35.2 ly) - Rutilicus is also known as Ruticulus (though this name can also refer to Beta Herculis), Zeta Herculis, and Gl 635. Nearby binary star system. Star A is a yellow-white or yellow sub-giant star. It is 50% more massive than the Sun, over twice its radius, and is about the same age. It probably began as a white or yellow white main sequence star. It is also known as HR 6212 and HD 150680. Star B is on the boarder between a yellow and orange dwarf star. It ranges from 7.8 to 21 AU away and was discovered by William Hershel in 1782. The star was once thought to be a member of the Zeta Herculis stellar moving group, but has since been removed as being too metal rich and the group renamed the Zeta Reticuli group. Star A has long been suspected of having a brown dwarf companion due to orbital peculiarities seen in Stars A and B.
        • Gliese 3966 System (3.4 ly; 37.5 ly) - Nearby red dwarf known as LP 275-68 and NN 3966.

Pollux Kingdom[]

6 Known Planets in 2 Systems

  • [1] Pollux System (54.5 ly; 33.6 ly) - Pollux is also known as Beta Geminorum, HR 2990, HD 62509, and Gl 286. It was originally called Polydeuces by the Greeks, after the immortal twin. The brightest star in Geminorum, which suggests it may have used to be the second brightest four centuries ago, and is the 17th brightest star in the sky. It is an orange-red giant star (K0 III) 1.7 times the Sun's mass and 8.8 its diameter and 724 MYO. It is the nearest (34 ly) giant star to the Sun. Its spectra has been used as a stable anchor point since 1943. It has one of the weakest measured magnetic field of any star. Planet Thestias was confirmed in 2006 that was first suspected in 1993. It orbits 1.64 AU in a circular path and is at least 2.3 times as massive as Jupiter. This is much nearer than the present habitable zone, which is centered at 5.7 AU. This is the brightest star in the sky known to have a planet. One of the first 20 exoplanet systems allowed to be given common names by the IAU. Named after the mother of Pollux, Leda. However, Leda is already taken as a moon of Jupiter, so a name derived from her father is used, which is sometimes used to refer to her or her sister..
        • Gliese 277 System (6.4 ly; 37.2 ly) - Nearby triple red dwarf in Lynx known as VV Lyncis and Gl 277. Star A is also a spectroscopic binary known as HIP 36626, BD+36 1638, G 87-44, and V 246. Star B is also known as Ross 989 and G 87-43.
        • BD+27°1348 System (7.7 ly; 40.1 ly) - Nearby red dwarf star known as BD+27°1348, Wo 9227, Gl 268.3, Hip 35191, G 109-55, and V 490.
        • Gliese 2069 System (9.1 ly; 28.7 ly) - Nearby possible five red dwarf star system or two separate systems nearby in the sky known as GJ 2069 and CU Cancri. Star A is divided into two parts, Aa, and Ab, and is also known as G 40-25. Star Aa is known as G 9-8, HIP 41824, and L1251-13, while star Ab is also known as G 40-26, and L1251-12. This was discovered to be the third known eclipsing binary system in 1999. This gave the most accurate mass for red dwarfs to date, and the first for an intermediary massed red dwarfs. A fifth star D was reported in 2000. The system is a member of the Castor Moving Group, giving an estimated age of 320 Million Years Old. The system is somewhat fainter than other stars of similar mass, providing evidence that there may be some light absorption by an undetected circumstellar disk. A flare was detected in 2009 and it was found to have one of the most energetic magnetic fields, and covered in many star spots.

Rho Cancri Principality[]

    • [5] Rho Cancri System (12.1 ly; 40.8 ly) - Copernicus is also known as Rho Cancri, 55 Cancri, Rho1 Cancri, HR 3522, Gl 324, and HD 75732. Wide binary star consisting of a sun-like primary (A, though super metal rich) and a red-dwarf secondary (B) separated by 1,100 AU, 41 light years away. Star A contains five exoplanets, the first system found with four or five planets. It has three tightly packed eccentric planets close in to the star, including planet Jannsen (e, hot Super Earth/Neptunian), Galileo (b, warm Jupiter), and Brahe (c, hot Saturn), followed by an eccentric Saturn in the habitable zone (Harriot, f) and a Jupiter analog, Lippershey (d). Planet e was heralded as the first Neptunian discovered. It was later found to be the shortest-period planet discovered (18 hours) and to transit. Its density was measured and determined to be rocky, and thus re-dubbed the first Super-Earth discovered. It was then the first super-Earth to have its light detected (by Spitzer in the infrared). The planet has about half of Neptune's mass, but is Earth-like in size and density (2.17 Earth Radius). Studies taking into account the composition of the star suggested that it was largely made of diamond, with graphite at the surface (the first diamond planet around a Sunlike star), and the first terrestrial found with fundamentally different surface composition and processes than Earth. This was later refuted when it turned out there wasn't as much carbon in the parent star as believed. Earlier studies that assumed an Earth-like composition suggested that it would be covered with an ocean of super-critical water. The brightness of the planet was found to have raised dramatically, possibly the aftermath of cloud cover due to a volcanic eruption. The brightness of the star (also closest known to transit and only known naked eye star to do so) makes it more easily studied than other hot super Earths. It was found to be dark and its sun-facing side hot enough to melt metal. It became the first super Earth to have its atmospheric composition measured (mostly hydrogen and helium with hints of hydrogen cyanide which would only dominate in a carbon-rich environment and no traces of water vapor) and temperature mapped, and the large hemispherical temperature differences suggest little atmosphere to transport heat. Planet b (one of the original 4 Hot Jupiters discovered) is the first "warm Jupiter" found to have a puffed up atmosphere and it probably at the outer limit from the star at which a planet can lose its atmosphere in this way. Its outer atmosphere skims the surface of the star, which was detected when attempting to detect an atmosphere around transiting Janssen. The strong interaction between planets Galileo and Brahe can be detected in measurements, and it took a while to find a fit that would allow them to survive over long periods of time. Harriot is a very eccentric Saturnian in the habitable zone. Planet d is a super jovian at Jupiter-like distances, which was the first found at true Jupiter distances and still the exoplanet discovered with dopplar spectrometry with the largest known semi-major axis. It was first thought to be circular, then eccentric, and then circular again. The distant outer star causes Lippershey's axis to flip on its axis every million years. Lippershey in turn causes the other planets to flip, including its star. The axis tilt of transiting planet e should be determined at some point. "Bode's law" predicts four undiscovered planets. One of the first 20 exoplanet systems allowed to be given common names by the IAU.
        • Gliese 359 System (8.8 ly; 39.8 ly) - Nearby red dwarf star known as Ross 92, Gl 359, and G 49-20, LHS 2171.

Denebola Kingdom[]

  • Denebola System (47.2 ly; 36.2 ly) - Denebola is also known as Beta Leonis, HR 4534, Gl 448, and HD 102647. It is the second brightest star in Leo and its name refers to the tail of the Lion. It is a white main sequence star, twice the Sun's mass with 50% more of its radius. It is a Delta Scuti type variable star, meaning that its magnitude varies very slightly over a period of a few hours. It has a circumstellar disk caused by collisions of smaller planetary bodies. This was first detected by excess infrared radiation detected in 1983. It is thought that one band starts at 0.13 to 0.43 AU, and another further out at 13 AU to 19 AU. The habitable zone ranges from 2.3 to 4.8 AU. It is part of the stellar association dubbed the IC 2391 supercluster.
        • Gliese 452.1 System (3.8 ly; 33.9 ly) - Nearby red dwarf star known as Ross 119, Wo 9375, Gl 452.1, G 12-4, and LHS 2472.
        • Gliese 3667 System (8.3 ly; 28.7 ly) - WD 1126+185 is also known as NN 3667 and PG 1126+185. Nearby white dwarf star. In 2003, parallax measurements (near zero, therefore, must be distant) gave results inconsistant with it being classed as a white dwarf star or a nearby object.

Alula Australis Principality[]

    • Alula Australis System (11.4 ly; 33.9 ly) - Alula Australis is also known as Xi Ursae Majoris, HR 4375, and Gl 423. Its name means "southern first spring". Nearby possible quadruple star system, consisting of two yellow dwarf stars with low mass spectroscopic companions. This was the first binary star found to be orbiting each other, found by William Herschel in 1780. Star A straddles the line between a white-yellow and a yellow dwarf star, is slightly more massive, and slightly smaller than the Sun. It is thought to be about 2 Billion years old and classified as a RS Canum Venaticorum variable type star. Star A is a spectroscopic binary, with star Ab orbiting from 0.8 to 2.6 AU, making any habitable planetary orbit unstable. Star B is another yellow dwarf star, about 90% as massive and as large as the Sun. It may be orbited by a brown dwarf or low mass red dwarf (Bb) in a torch orbit. The pair is separated from Stars A by 12.5 to 39.9 AU. A fifth orange dwarf Bc component has been suspected at 450 AU, but appears not to move with the system. A second brown dwarf (T class) in the system was found in 2012 sharing the system's motion at 4000 AU.
        • Luyten 1545-74 System (4.4 ly; 31.9 ly) - L 1545-74 is also known as GJ 1138 and LHS 293. Nearby red dwarf star in Leo.
        • Gliese 436 System (4.5 ly; 33.3 ly) - AC+27°28217 is best known as Gliese 436. The second known red dwarf planetary system. Contains one of the first Neptunians discovered and a few potential planets. The star is about half the sun's mass. It is over 11 Billion years old and may be a part of the old disk of the Milky Way. Planet b temporarily later found to be the smallest exoplanet (about Uranus' diameter, though over 50% its mass) known to transit its host star and is currently the nearest (33 ly). Its temperature (712K) was measured to be higher than what it would be purely from radiation (520K), perhaps due to a greenhouse effect, somewhat higher than Venus. It was originally thought to have a layer of "hot ice", water solidified due to high pressures. It turned out that it was larger than thought and hot ice was not needed. It could still be a rocky super-Earth. It was later found to have a remarkably low levels of Methane and high levels of Carbon Monoxide for its 800K temperature. Possible explanations include Methane being changed into hydrocarbon polymers due to its star's ultraviolet radiation, CO being drafted upwards with winds, or observational defects. Later, due to lack of detection of chemical signatures through the backlit atmosphere, it was concluded that high altitude clouds, perhaps made of potassium chloride or zink sulphide dust, were blocking the detection. This could be the first detection of clouds of a Neptunian. An alternate theory is that the atmosphere is filled with heavy compounds, such as water, carbond dioxide, which would compress the atmosphere and make it difficult to detect. After detection of a huge comet-like tail of Hydrogen trailing and wrapping around its orbit led to the most recent theory that it lost its Hydrogen to uv radiation and was left with a Helium dominated atmosphere with plenty of CO instead of CH4. It's significant eccentricity suggests a possible neighboring planet. Planet c was announced to be the smallest known exoplanet (1.5 Earth's diameter), but was later retracted because variations in transit timing of the first planet did not occur and the proposed orbit would be unstable. It is still thought that a second planet of some kind is possible in the system. Candidate UCF-1.01 was detected by a student in the UCF's astronomy department using the Spitzer Space Telescope. It is about 2/3 Earth's diameter (smaller than all but one confirmed exoplanet), orbits around its star in 1.5 days, and at 1000F may be a lava world without an atmosphere. UCF-1.02 also may exist. Both are thought to be about 1/3 as massive as the Earth, but are too small to get their mass measured and thus too small to be confirmed with present technology.

    • 61 Ursae Majoris System (12.4 ly; 31 ly) - 61 UMa is also known as HR 4496, Gl 434, HD 101501, and NSV 5291. Nearby late yellow dwarf star. It is just barely visible to the naked eye. Its spectrum has been used as a stable anchor point since 1943. Its chromospheric activity suggests it younger than 500 Million Years old, but its lack of an easily observable disk suggests it is over 1 Billion years old. Lack of detection of large planets in tight orbits bodes well for finding a future habitable planet. Its variability was studied in 1953 in hopes of finding it was an eclipsing binary. It lies in the same line of sight as the sub-giant star HD 101212, though it is unclear if these are gravitationally bound or even in proximity of each other. In Star Trek, this is the system the planet Archer IV belongs to.

Groombridge 1830 Principality[]

    • Groombridge 1830 System (14.5 ly; 30 ly) - Groombridge 1830 is also known as HR 4550, HD 103095, and Gl 451. Nearby dim yellow subdwarf star. It was first mentioned in Groombridge's catalog of circumpolar stars. It was found to have the highest proper motion of any star by Argelander in 1842 (replacing 61 Cygni), and is now known to have the third highest. It is likely a halo star, and has not evolved onto the main sequence despite its old age 5 or 10 billion years old. Being a halo star that does not follow the rotation of the galaxy explains its high proper motion. It is part of the Groombridge 1830 Moving Group, which consists of several other subdwarf stars. Van de Kamp recorded a flare which he assumed was a dim companion star. It has since been found to undergo superflares.
        • BD+36°2219 System (2.3 ly; 28 ly) - BD+36°2219 is also known as G 148-13 and Gl 450. Nearby red dwarf star in Ursa Major. Possible spectroscopic binary.

        • Gliese 487 System (5 ly; 33.3 ly) - Nearby red dwarf flare star also known as HIP 62556. Its documented distance of under 100 light years is due to a Hipparcos error.
        • Gliese 1187 System (6.5 ly; 36.5 ly) - Nearby red dwarf star known as GJ 1187, G 201-27, and LHS 3006.
        • Gliese 424 System (10.3 ly; 29.7 ly) - Gl 424 is also known as HIP 55360. Nearby red dwarf star in Ursa Major. Its given distance of under 10 parsecs is due to a Hipparcos error.
      • Struve 1321 System (15.8 ly; 20.5 ly) - Struve 1321 is also known as Gl 338, Sigma 1321, and HD 79210. Nearby double system of late orange dwarf flare stars. First observed as a binary star by Struve in 1817. They are separated on average by 108 AUs. Star A is also known as HD 79210, while B is also known as HD 79211. In the 1970s and 1980s, each star was thought to have an unseen companion per radial velocity measurements, which have since been disproved.
        • Luyten 97-12 System (9.1 ly; 26.7 ly) - GJ 1105 is also known as HIP 38956, G 111-47, L 97-12, and LHS 1963. Nearby red dwarf star in Lynx. Its distance of under 10 parsecs is due to a Hipparcos error.
        • Ross 986 System (9.1 ly; 20.9 ly) - Ross 986 is also known as Gl 268. Nearby binary red dwarf star in Auriga. Star A is a flare star known as QY Aurigae. Star B is A's spectroscopic binary pair and they orbit each other in 10.4 days. The pair form a RS Canum Venaticorum variable star, which are two stars whose brightness varies due to their strong magnetic fields due to their rapid rotation, which is accelerated due to tidal effects caused by their proximity. Ultra-precise mass measurements were obtained in 2008. Precise orbital measurements taken in 2012 are the best for any visual binary and compete with the best measurements taken for eclipsing binaries.
        • Gliese 3417 System (9.3 ly; 25.4 ly) - Nearby binary red dwarf star known as G 250-31, LHS 1885, and GJ 3417. Once thought to be within 10 parsecs, now thought to be 37.3 ly away.

Zavijava Client Kingdom[]

  • Zavijava System (8 ly; 35.5 ly) - Zavijava is also known as Beta Virginis, Alaraph, HR 4540, HD 102870, and Gl 449. Actually the fifth brightest star in Virgo, named for the "corner/kennel" of the Arab Dogs. This is the star that Einstein used to calculate the speed of light with during a solar eclipse, as it was close to the sun. Yellow-white main sequence star that is about to evolve into a sub-giant star. Has about 1.3 times the Sun's mass and 1.7 its radius. Its current habitable zone is 1.87 AU, although it has recently shifted outwards. Jovian planets were suspected in 1998, but none have been confirmed. Has two optical companions and is suspected of being a spectroscopic binary.

Porrima Client Kingdom[]

  • Porrima System (13.7 ly; 38.5 ly) - Porrima is also known as Gamma Virginis, Arich, and Gl 482. Named after two of two ancient sister goddesses of prophesy. A twin pair of bright Yellow-white main sequence stars (both F0 V) in Virgo. Star A is also known as HR 4825 and HD 110379, and Star B is known as HR 4826 and HD 110380.

61 Virginis Principality[]

    • [3] 61 Virginis System (15.4 ly; 27.7 ly) - A system containing a 5.1 ME Hot Super-Earth b (which is hot enough to have emissions on its night side) and one and possibly two other further out Neptunians (c and d [unconfirmed] and possibly a fourth), and a massive Kuiper Belt around a very Sun-like star only 28 light years away. All planets would fit inside Venus' orbit and have high eccentricities, especially the outermost one. This is the closest planetary system around a G-type star, which is one of the only very sun-like stars visible to the naked eye. It is the first non-borderline G-class main sequence star found to have a super-Earth. A lack of a Jovian planet and an unseen further out Neptunian may explain the large amount of cometary debris detected. Systems like this may avoid a heavy bombardment period, but instead undergo a steady rain of occasional cometary impacts for billions of year. Of the six sunlike stars within 10 parsecs, this star would be the one most likely to have an older version of Earth orbiting it. This postulated planet would have only microbes left as its star became hotter.

        • [6] BD-11°3759 System (3.7 ly; 19.9 ly) - BD-11°3759 is better known as Gliese 581. Small nearby Red Dwarf with six planets in tight circular orbits. Several planets were announced in the habitable zone, but have since been retracted due to being due to sunspots rotating in view during it's 130 day rotation. E is the smallest known dopplar-detected exoplanet and a Super Mercury, b is a hot Neptunian, c is a super-Venus and the first detected in the HZ (initially heralded as habitable, but later thought too hot due to the greenhouse effect). G (1/4 stellar rotation) was the most controversial heralded as the first habitable Super-Earth and "Eyeball Earth", but was disproven. D (1/2 stellar rotation) was later thought to be an even more promising planet for life as it was big enough for a decent greenhouse effect even though it was at the outer edge of the habitable zone, was later thought to also not exist, but then its existence was re-affirmed. F was thought to be a cold super-Earth, but also disproven. The star is not very active. A massive Kuiper Belt was found, which may have been allowed to exist because the system lacks a Jovian class planet. A further out Neptunian may be responsible for the cometary collisions that produced the debris.

Beta Pictoris Client Kingdom[]

(Client Kingdom of What?)

  • Beta Pictoris System - Young massive star with the first discovered circumstellar disk and the source of most interstellar meteorites in the Solar System. Comet crystals were found to be similar composition as those in Solar System. The first exo-comet was discovered in this system in 1983 and is the only star known with a detected comet known to also have a planet. Hundreds of comets detected by transit, of which on average of 6 transits occur in a 30 minute spetra, have been placed into two groups. One family (Population D for "deep" absorption lines) were older comets depleted of their volatiles and trapped in mean motion resonance with planet b or another undiscovered one. The other is fresher (Population S for "shallow"), emit more dust, follow similar orbits, and may have been formed after the breakup of a larger object. Contains the youngest known exo-planet, which shows that Jupiter-like planets can form much quicker than previously believed. It is the closest-in exoplanet photographed and is at 8 AU and 7-11 Jupiter Masses and orbits in 20 years. This planet was first hinted at by studying dust disks in 2003 and first photographed in 2003, but it was not confirmed and was lost. It was imaged again in 2008, and became the first imaged exoplanet confirmed to move around its star in 2010. It has an effective temperature of 1,100 to 1,700C, showing that it is still warm and has retained much of its heat from its formation. Evidence of a planetary transit in 1981 was found in record. It was originally thought that a second planet must have caused a tilt in one of the disks, but now it known that the first planet is. Models show that it could create waves and spirals in the disk. Some data suggests the planet is unusually wide, perhaps evidence of a ring system around it. The planet is traveling through a relatively dust-free gap in the debris disk, and thought to be clearing it. The planet is losing momentum as it travels through the debris disk. A large belt of carbon monoxide 50-160 AU concentrated at 85 AU has been observed, possibly caused by collision of comets. A Saturn sized planet interior to the belt that is not currently detectable due to being edge on in the disk could be shepherding it. It is possible that diamond-planets are forming in the disk. A cubesat could target this star in search of a second planet using the transit method since the system is edge-on. Principle member of the Beta Pictoris Moving Group.
