Proxima Centauri c is a super-Earth or mini-Neptune about 7 times as massive as Earth, orbiting at roughly 1.49 AU (223 million km; 139 million mi) every 1,928 days (5.28 yr). [3] Due to its large mass and its distance from Proxima Centauri, the exoplanet is uninhabitable and too cold for liquid water to exist on the surface, with an ...
