They collide with each other. Since each satellite is going at 18,000 miles per hour, collisions are bad. They create even more space junk than is already up there, posing the possibility of even more collisions.
there is no satellites orbiting Saturn
There are thousands of satellites in Earth's orbit, with estimates ranging from 2,200 to over 3,000 active satellites. Additionally, there are many more inactive or defunct satellites and debris in orbit.

Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.

With large number of low-earth-orbit satellites and the geo-synchronous orbit stuffed full of communications satellites, there aren't all THAT many "medium" altitude satellites. But there are some. The GPS navigation satellites, for example, are in highly inclined 12-hour orbits, and an unknown number of military "spy" satellites are in that middle range.
Thousands, but the actual number is classified and varies from week to week as satellites de-orbit and new ones are launched.
There are currently 30 healthy GPS satellites in orbit.
DISH Network currently owns & leases a total of 14 satellites.
