The picture below shows all the Starlink (i.e. SpaceX) satellites in low-earth-orbit at a single point in time. Go to the Privateer link and you'll start with all the satellites from over 100 constellations and you can use a few filters to see just a portion of interest. A large number of the results fall into the Uncategorized category and zooming out reveals lots of that space junk. Seems like it's pretty crowded up there already and the thousands of satellites expected to launch each year will make keeping track of what's where even more important.
