Super-Neptune

Un super-Neptune est un objet astronomique plus massif que la planète Neptune et de constitution interne similaire. Ces planètes sont généralement décrites comme étant environ 5-7 fois plus grandes que la Terre avec des masses estimées entre 20 et 80 M[1], au-delà elles sont généralement appelées des géantes gazeuses.

Il y a eu relativement peu de découvertes de ce genre de planètes. Des exemples connus sont Kepler-101 b, HAT-P-11 b, K2-33 b[2],[3] et WASP-107 b.
