WASP-31b is a low-density (puffy) "hot Jupiter" extrasolar planet orbiting the metal-poor dwarf star WASP-31.[1] The exoplanet was discovered in 2010 by the WASP project.[2][1] WASP-31b is in the constellation of Crater,[3] and is about 1305 light-years[4] (light travel distance) from Earth.[2]
Characteristics
WASP-31b is a low-density (puffy) "hot Jupiter" exoplanet with a mass about 0.48 times that of Jupiter and a radius about 1.55 times that of Jupiter.[2][1] The exoplanet orbits WASP-31, its host star, every 3.4 days.[2]
