Moons of Rogue Planets Could Harbor Oceans for Billions of Years via Tidal Heating and Hydrogen Atmospheres
To the point
David Dahlbüdding and colleagues from ORIGINS at LMU Munich and the Max Planck Institute say moons around rogue, star-free planets could sustain oceans for up to about 4.3 billion years thanks to tidal heating and a hydrogen-rich atmosphere, broadening the search for life beyond suns.
