WASP-5b is an extrasolar planet orbiting the star WASP-5 located over 967 light-years away in the constellation Phoenix. The planet's mass and radius indicate that it is a gas giant with a similar bulk composition to Jupiter. The small orbital distance of WASP-5 b around its star mean it belongs to a class of planets known as hot Jupiters. The proximity of WASP-5b to its host causes it to have an atmospheric temperature of approximately 1717 K.[1]
