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
Data comes from NASA planetary fact sheets (amazing resource btw).
Overall equation structure:
Circular area that can receive sunlight: pi x radius ^ 2
Total incoming power : solar irradiance x circular area
Spherical area : 4 x pi x radius ^ 2
Black body radiation : stefan-boltzmann constant x Area x Temperature ^ 4
You know have incoming power and outgoing power.
Percentage : 100 x (Outgoing - incoming) / outgoing
