  • Rogue planets have been ejected from their planetary system. We investigate the possibility that a rogue planet could maintain a liquid ocean under layers of thermally insulating water ice and frozen gas as a result of geothermal heat flux. We find that a rogue planet of Earth-like composition and age could maintain a subglacial liquid ocean if it were ≈3.5 times more massive than Earth, corresponding to ≈8 km of ice. Suppression of the melting point by contaminants, a layer of frozen gas, or a… CONTINUE READING
