So while spending hours on wikipedia reading up on colonization of planets in our solar system I discovered we have a dwarf planet called Ceres in our astroid belt. I guess it was only recently considered a dwarf planet, but the thing is all round and such… and planet-y. We need to invent giant rockets to push these things closer to the sun so we can live on them. Or visit them. Or at least I would have liked to have learned about these things years ago.
