WASP-5b is an exoplanet orbiting the star WASP-5 located approximately 1000 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 means it belongs to a class of planets known as hot Jupiters. The planetary equilibrium temperature would be 1717 K, but the measured dayside temperature is higher, with a 2015 study finding 2500 K and a 2020 study finding 2000 K. A study in 2012, utilizing the Rossiter–McLaughlin effect, determined that the planetary orbit is probably aligned with the equatorial plane of the star, with misalignment equal to 12.1°.
