In those visualization aren't those orange spheres kilometers wide? I feel like we're still missing just how big space and the gap between the tiny objects is and that visualization blows it all out of proportion.

These visualizations are great to give you a basic sense of whats going on up there, but they do not represent any sort of realistic scale. If they did then the visualization would be boring because everything would be WAY too small.

Also it is stuck with a relatively 2D format. Are the satellites really intersecting or is there 10km of vertical distance between them? Its hard to tell with these forms of visualization.
