Exoplanetary Scratchpad |
Nearby (39 ly) red dwarf star with a transiting Venus type planet. Was the closest known Earth-sized planet when discovered. Planet is 1.2 the size and 1.6 the mass of Earth. It orbits once every 1.6 days and expected to be a little cooler than Venus, at 500F temperatures. It is oven hot, but cooler than any other Earth sized planet known, and likely tidally locked. Likely cool enough to retain a significant atmosphere. Since it is nearby and around a dim start, it is the first earth-sized planet whose atmosphere can be studied. Much closer than Earth-sized exoplanets found in their habitable zones, so it is more easily observed. Its transit was not detected on a single pass, but over multiple passes superimposed on each other.
