WASP-5 is a magnitude 12 yellow dwarf star located about 910 light-years away in the Phoenix constellation.[2] The star is likely older than Sun, slightly enriched in heavy elements and is rotating rapidly, being spun up by the tides raised by the giant planet on the close orbit.[3]
Planetary system
This star has one extrasolar planet WASP-5b detected by the SuperWASP project in 2007.[4]
