Yes, the planets are pretty much all copies of our solar system. (I just wish I had remembered that before I started.) I usually go for Marsish planets also, but I thought the brown tileset were kinda neat. I really liked the Ceres Asteroid (I hadn't seen that before). I think I might start a colony on that. There's also an instance of our own moon (though I forget where off hand. I suppose that's why I made the look up table).
No guarantees on 100% accuracy.
