SpaceEngine

About

SpaceEngine is an open-universe space simulation game that models the universe at a 1:1 scale, allowing exploration of real-world celestial objects and procedurally generated ones. Players can navigate between galaxies, stars, and planets using flight mechanics with Newtonian physics, while time acceleration enables observation of orbital motions and cosmic events. The game includes a planetarium mode with cataloged data and supports user-created mods for custom content.
