Paint surfaces, reshape rocky worlds, add rings and atmospheres, and give every space friend a face.
Explore from every angle
Fly through the system, follow an orbit, look through a planet's eyes, or walk along a tiny horizon.
Made for curiosity
Design it. Set it spinning. Go visit.
Adjust size, color, orbit, spin, faces, clouds, rings, and more. Paint a flat map, sculpt mountains and craters in 3D, or slow time down to watch a moon cast its shadow.

For grown-ups
