An Interactive Space Simulator "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, the nearest 1000 stars to our Sun, and our local group of galaxies."
