WASP-5 is amagnitude 12G-type main-sequence star located about 1,020light-years (310parsecs) away in thePhoenixconstellation.[2] The star is likely older than the Sun, slightly enriched in heavy elements and is rotating rapidly, being spun up by the tides raised by the giant planet on a close orbit.[5]
This star has oneexoplanet,WASP-5b, detected by theSuperWASP project in 2007.[3]
