A bit different from Cosmonium or SpaceEngine, but I've been building a FOSS space simulator called Spacekit.js: https://typpo.github.io/spacekit/ https://typpo.github.io/spacekit/ It's mostly focused on modeling orbits rather than beautiful free-camera renderings, but the visuals aren't terrible and it can model our solar system, exoplanets, render shapes and textures of asteroids, planets, etc. It's based on the engine I used to build this meteor showers simulation, which has appeared on HN before: https://www.meteorshowers.org/ https://www.meteorshowers.org/
