  • As a "this is also in current events" ( Successful Earth flyby improves Juice’s course to Jupiter - https://www.esa.int/Science_Exploration/Space_Science/Juice/... )

    Doing a search for JUICE as a spacecraft pulls that one up and shows its impressive pre-Jupiter orbital mechanics.

  • Quite incredible how much manmade crap there is up there, and much of it probably useless, and a potential problem for the satellites which are of actual use.
  • Celestia did all of this and more. 10+ years ago.

  • Beautiful site. I love how tranquil the scene becomes when satellites and spacecraft is unchecked. Thanks for that SpaceX (and others).
  • Wow, speedy and convenient! Well done!

    Some insights:

    * There is sooo much space debris! Dead sattelites and rocket bodies

    * Starlink put up a hell of lot of satellites, too.

    * There is a pretty dense sphere of items around the earth at geo-stationary orbit, a bit like a mantle; but most of all in a circle on that sphere.

  • Just spent a little time following Europa Clipper, it will fly by Earth very soon! If you zoom out from Earth, it's already pretty close. This will be its second gravity assist after Mars. Very cool site!
  • Brilliant project and very well done.

    That aside, it is just astounding that even a moderate laptop just plows through this as thought it is nothing.

    I remember doing orbital calculations on a 486DX with about 30 objects at just barely 30fps thanks to the FPU. That was pretty good for me. Without the FPU you would get maybe 2FPS. Now, you can just throw a half million around at 60fps+ in a web browser. Crazy!

  • 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.
