How are you sourcing the spacecraft positions from JPL? Are you just grabbing a huge list of state vectors?
My old day job was to compute asteroid positions for NASA telescopes, if you are interested in orbit prop you may be interested in:

I made an asteroid only version of yours earlier this year, where it does full orbit propagation in workers:

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!
I love this; also runs surprisingly smoothly (at least in browser; didn't check mobile). Also beautiful and hypnotic in motion. What's the next step that you want to take to develop it (not that there needs to be one)?
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.
Everyone talks about the ringed planets, but I've never seen Earth mentioned of having a ring. I've also never seen mentioned that the rings were not man made as a qualifier. Yet, there it is, very clearly visible when zoomed out.
One of the things that I noticed was how far away Parker was from the sun. I know it has a crazy orbit, but seeing it at a scale reference just emphasizes how its orbit is complicated.
Also, checking out the platforms around L2. Euclid and JWST are no where near each other which again, just emphasizes how much space there is in...space.
Even more than that. Of the 35k tracked "Satellites and spacecraft", more than 12k are debris bringing Starlink to 1 in 2. If you look only at Active known satellites, around 2 in 3.
From Starlink's page on Wikipedia: "Starlink accounts for approximately 75% of all active maneuverable satellites in Earth orbit"
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.
I think it's pretty obvious the satellites aren't drawn to scale, given they don't change in size when zooming in/out.
I assumed they meant that relative distance from Earth or orbit is to scale, not that the size of the dots was to scale, but I could be wrong
A way to zoom that is faster than mouse wheel would be nice. Takes forever to zoom out a long way!
Being able to zoom on mobile at all would be great. And a way to close all of the overlay panels!
Thanks, I've already fixed it.

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).
This is amazing. Well done. How long did it take to make?
Seconded. Great work.
Thanks! It's a byproduct of another project, so hard to say exactly. A few evenings.
There are way more asteroids near the Earth than I thought.

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.

What's with those giant blobs of asteroids offset in jupiter's orbit by like 60deg on either side?

Almost 1 in 3 tracked spacecraft is Starlink, is that accurate?
Even more than that. Of the 35k tracked "Satellites and spacecraft", more than 12k are debris bringing Starlink to 1 in 2. If you look only at Active known satellites, around 2 in 3.

Probably correct. Random link from 2023 (~50%) https://www.springco.co.uk/what-do-satellite-constellations-...
Super! Not easy to select or center on a planet though.
Very interesting!
great project!!!!
