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. WASP-3b undergoes no detectable gravitational tugging from other bodies in this system.[1] See also
