    Tidal forces add a little bit of energy due to friction in case that wasn't clear. The surface of its planet is rubbing against itself a little.

    Isn't there another way that the water stays liquid? I know that water freezing is an exothermic reaction as the water molecules stop moving, that on a big enough scale would heat the surrounding water wouldn't it?

    Life on dying rogue planets would see Earth as an opportunity. Service guarantees citizenship.

    surely a moon orbiting a planet and 'needing it like dough', keeping it warm, breaks the laws of thermodynamics? would the moons orbit generate heat forever? surely it can't
