TNO = trans neptunian object, basically far out dwarf planet
Obviously there would be less sun to greenhouse, but theoretically could that be a way to have closer-to-earth habitats far away from a star?
edit: the TNO does not have to be like Pluto, it can be bigger or have different conditions
If we are starting the the chemicals being cases, through external means or the TNO not starting as a TNO, would it be able to sustain enough heat to keep it that way?
