Author here. It's a browser view of the Solar System at real scale, with its current state, plus the objects around Earth from the CelesTrak catalog.

Data: CelesTrak TLEs (SGP4), asteroids and comets from JPL SBDB, spacecraft positions from JPL Horizons. Updated daily.

Rendering is WebGL2, orbit propagation runs in web workers. The asteroid set (~30 MB) loads in the background.

The time slider runs forwards and backwards; satellites appear and disappear by launch date.

Is it really? I don't think you could see the satellites, if they weren't drawn at 1000x scale. I am wrong?

At real scale, i would expect to not see anything.

A way to zoom that is faster than mouse wheel would be nice. Takes forever to zoom out a long way!
