All the liquid methane you can ask for, only it’s a billion miles away. It’s the only place in the solar system with a solid surface and an atmosphere thicker than earth’s. It’s even the same composition as earth’s except for the lack of oxygen.
With all that methane around,likely not a good idea to introduce oxygen. Just saying.
Of course I’m forgetting Venus. What I mean is... Oh never mind.
