WASP-50, also named Chaophraya, is a G-type main-sequence star about 594 light-years away in the constellation Eridanus. The star is older than the Sun and slightly depleted in heavy elements compared to the Sun, and has a close to average starspot activity. Despite its advanced age, the star is rotating rapidly, being spun up by the tides raised by a giant planet on a close orbit.
