Universe Sandbox

Universe Sandbox | created by Dan Dixon: "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.
