Yes. That and all I saw in my first preview of it was Earth and the Moon aswell as several small flat pieces of floating land. Unless the other planets are much farther and I was just too lazy to find them, don't bother dling this unless you want an Earth and Moon planet map.
Most of them are gas giants, there is no light but the colors are so bright, it makes your light auto-on
Building planets- Earth, moon, space station, mars, some gas giants have moon platform things, and there is a pluto, its really small it doesnt need a skysphere
