HD 63454 b is an extrasolar planet located approximately 117 light-years away in the constellation of Chamaeleon, orbiting the star HD 63454. It is at least 38% as massive as Jupiter, and orbits very close to its host star, even closer than the famous 51 Pegasi b. Its close orbit means it belongs to a class of exoplanets known as hot Jupiters. This planet has one of the least eccentric orbits.[1]
