Is there enough matter for a serious political faction to subsist off of? The total mass of the asteroid belt is calculated to be 3% that of the Moon [1] https://en.wikipedia.org/wiki/Asteroid_belt https://en.wikipedia.org/wiki/Asteroid_belt We only use a small fraction of matter on the Earth, so maybe a good sized comet can host habitation. But the solid planets and moons are where humanity could thrive. The gas giants have too a gravity well, we'd need some seriously advanced propulsion to make it off, but there's 317x more matter on Jupiter than Earth.
