Sample (Year)Edit

Example PlanetsEdit

  • OGLE-TR-113 System - A binary orange dwarf star 1800 ly away in a crowded star field in Carina. It contains the second discovered Very Hot Jupiter (34 hours, 0.023 au, 1.3 MJ) and one of the first discovered transiting planets. At one time it was the only known transiting Hot Jupiter with a surface gravity greater than Jupiter's. Between 2002 and 2009, its transit times were found to shorten by 60 ms per earth year. This indicates that it is slowly spiraling towards its sun, the first exoplanet found to be doing this, and may get ripped apart by its star in 1.4 million years, when its period is reduced to 10.8 hours. An alternate explanation may be that an unseen planetary companion is causing the timing differences.
