WASP-3b is an extrasolar planet orbiting the starWASP-3 located approximately 800 light-years away in the constellationLyra. 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]
WASP-3b undergoes no detectable gravitational tugging from other bodies in this system.[2]
The study in 2012, utilizing a Rossiter–McLaughlin effect, have determined the planetary orbit is probably aligned with the equatorial plane of the star, misalignment equal to 3.3+2.5 −4.4°.[3]
