HAT-P-24 is an F8 dwarf star about 413 parsecs away.[2] A planet was discovered with the transit method by the HATNet Project in 2010. HAT-P-24b, is a typical hot Jupiter orbiting in only 3 days.[4]
Planetary system
In 2010 the HATNet Project announced the discovery of a hot jupiter type gas giant extrasolar planet in orbit around this star. Following the designation scheme used by the HATNet Project, the star is designated as HAT-P-24, and the planet itself HAT-P-24b.[4]
