SpaceEngine is a 1:1 scale science-based Universe simulator, featuring billions upon billions of galaxies, nebulae, stars, and planets, all shown at their full real-world scale. Explore Earth and our neighboring worlds in the Solar System, orbit a black hole in a galaxy billions of light-years away, or visit anything in between seamlessly, with no transitions.

All of time and space are yours to explore – cruise between the stars at a million times the speed of light, and accelerate time to watch the orbital motions of a thousand worlds play out before your eyes. Every planet you encounter in your journey will feature procedural 3D terrain with detailed textures. Everything you see in the sky – stars and galaxies, planets and moons, asteroids and comets, black holes and neutron stars, star clusters and nebulae – are yours to explore at the press of a button.
