    Interesting alternate biosphere idea on Twitter

    I'm having a conversation with a guy on Twitter about a potential biosphere.

    A rogue planet, or, more likely in this scenario, a small brown dwarf, orbited by two planets or moons. Each is about the size of the Earth, the innermost is a super-Io, so torn by tidal forces that it exists as a permanent sea of lava. The other is kneaded a little less, but as a result has an atmosphere and surface water. Could the light from the inner moon provide enough energy for a form of photosynthesis? Such as that which is hypothesised to exist around red dwarfs?

    Even a moon or planet with a totally molten surface, would not give off anywhere near the light and heat of the dimmest red dwarf star. Even the Brown Dwarf it orbits would likely far outshine that inner moon.

    What if it was made of molten metal, rather than rock?

    Would that make a difference? The amount of tidal energy pumped into it would still be the same.

    Just to add what Noclevername said, to a great extent, all that matters is the temperature of the object, and not the composition.
