WASP-22b, also named Koyopa', is an extrasolar planet orbiting the Sun-like star WASP-22 320 parsecs (1,000 ly) in the constellation Eridanus.[1][2] This hot Jupiter has an orbit of 3.53 days and a mass of 0.617 MJ and was detected by transit via SuperWASP. The system is a hierarchical triple system.[3]
