Real-time Solar System
Every tracked satellite and half a million asteroids, where they are right now
It turns public orbital catalogues into something you can explore in a browser tab, which makes it a ready teaching aid and a quiet benchmark for how far WebGL can go.
A browser view of the Solar System that plots current positions of planets, spacecraft, satellites and roughly 526,000 asteroids and comets. Satellite orbits come from CelesTrak TLEs propagated with SGP4, small bodies from JPL's database and spacecraft from JPL Horizons, refreshed daily and rendered with WebGL2 and web workers. You can drag, zoom, fly with WASD and click any object for its card and orbit. Free, no account. The interface is in Russian and mobile zoom is still rough.
