Smash moons into planets, create new stars, and build new worlds from spinning discs of debris. Explore our solar system in 3D 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 hundreds 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.
