WASP-10 is a star 461 light-years away in the constellation Pegasus. It hosts a transiting planet discovered by the SuperWASP project. The star is likely older than the Sun, has a fraction of heavy elements close to the solar abundance, and is rotating rapidly, being spun up by the tides raised by the giant planet on a close orbit.
Planetary system
WASP-10 hosts one confirmed exoplanet, WASP-10b. It is a hot Jupiter discovered in 2008. A candidate second planet with a 5-day period, WASP-10c, was inferred from transit-timing variations of WASP-10b in 2010, but this was refuted in 2013. Instead, there may be a super-Jupiter planet or brown dwarf on a wide (at least 5 AU) orbit, based on radial velocity observations.
