WASP-3b is an extrasolar planet orbiting the star WASP-3 located over 727 light-years away in the constellation Lyra. It was discovered via the transit method by SuperWASP, and follow up radial velocity observations confirmed that WASP-3b is a planet. The planet's mass and radius indicate that it is a gas giant with a similar bulk composition to Jupiter. WASP-3b has such an orbital distance around its star to classify it in the class of planets known as hot Jupiters and has an atmospheric temperature of approximately 1983 K.[1]
In 2010, measurements of transit timing variations of the planet WASP-3b were used to infer the presence of a second planet in the system, designated WASP-3c.[2] The discoverers note that further observations are needed to confirm the existence of this second planet.[3]
