If your definition for crowded is "mean distances between satellites is more than 1000km." Space is big. The geostationary orbit has a diameter of 265000km, and there are something like 200 satellites up there. The lower orbits have a lot of gunk on them, but this asteroid will only cross the geostationary orbit. It's pretty damn unlikely it will hit anything.
