Universe Sandbox

Check out this cool program: you can smash planets together, introduce rogue stars, and build new worlds from spinning discs of debris. Fire a moon into a planet or destroy everything you've created with a super massive black hole.

You can simulate and interact with:

Our solar system: the 8 planets,160+ moons, and hundereds of asteroids
Nearest 1000 stars to our Sun
Our local group of galaxies
An unlimited number of fictional scenarios

Tinker with your creation or sit back and watch the effects of gravity unfold. It's fun, accessible, and easy to use.
