WASP-24 is an F-type star with the hot Jupiter planet WASP-24b in orbit, about 1,075 light-years away in the constellation Virgo. WASP-24 is slightly larger and more massive than the Sun, it also has a similar metallicity and is hotter than the Sun. WASP-24 was first observed by the SuperWASP planet-searching organization, which flagged it as a potential host to a planet before following up with radial velocity and spectral measurements. Analysis of these confirmed the planetary nature of WASP-24b, which was later released to the public on the SuperWASP website.
An eclipsing binary pair of companion stars were identified by a 2019 study using Gaia DR2 data. They are separated by 21.8 arcseconds from the primary star, corresponding to a distance of 7097 AU.
