Eta² Hydri b (η² Hyi b / η² Hydri b), often cataloged as HD 11977 b, is an extrasolar planet approximately 217 light-years away in the constellation of Hydrus. The presence of the planet around an intermediate-mass giant star provides indirect evidence for the existence of planetary systems around A-type stars.
