WASP-5
WASP-5 is a magnitude 12 G-type main-sequence star located about 1,020 light-years (310 parsecs) away in the Phoenix constellation. 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.
Planetary system
This star has one exoplanet, WASP-5b, detected by the SuperWASP project in 2007.
