About

Space Simulator Online is a free solar system and universe simulator built by Run Cheng in hand-written WebGL2, with no engine. The Sun, planets, moons and comets sit on their real orbits for any date from 1800 to 2100, using NASA and JPL data, and you tap a world to fly to it and land on it. The side list also covers dwarf planets, asteroids and spacecraft such as Voyager and Juno. Other modes open the Milky Way, more than 6,000 exoplanets and a WebGPU simulation of colliding galaxies.
