WASP-6b is an extrasolar planet approximately 1000 light years away in the constellation Aquarius. It was discovered in 2008, by the WASP survey, by astronomical transit across its parent star WASP-6. This planet orbits only 4% that of Earth-Sun distance. The planet has mass half that of Jupiter, but its insolation has forced a thermal expansion of its radius over that of Jupiter.
