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.
