Zombie Gunship Survival

Make your own solar system with this simple, physics based, sandbox game.

There’s now a Planet Families 2 that includes 3D views and other new features. Requires at least Android 4.4/KitKat: Planet Families 2

Drag and drop planets and stars to make your own solar system. The physics engine will calculate how gravity between all of the asteroids, planets, and stars affect one another while they move through space.

Can you make a stable solar system? How about a stable solar system with a binary star?

Planet Families works on both phone and tablet devices.
