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

There are many satellites that orbit the earth in a day or less. All of them are man made. The only real satellite that orbits the earth is the moon. That takes 28 days to complete a single orbit.

There may be as many as 25,000 artificial satellites orbiting Earth, although only around 8,300 are on record and less than 5000 are active. Our planet has only one natural satellite, the Moon.

Gravity keeps satellites in orbit. The closer you are to the Earth, the faster you have to go to maintain your orbit. At low Earth orbit, the altitude of the Space Station, you make an orbit every 90 minutes. At the Moon's distance you need over 27 days to go around the Earth. In-between there is an altitude which matches the rate of the Earth's rotation. Many satellites orbit at this altitude.
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.
There are hundreds. If that seems like "many" to you, then the answer is 'yes'.
Thousands, but the actual number is classified and varies from week to week as satellites de-orbit and new ones are launched.
At present there are around 24-32 satellites orbiting in medium earth orbit(11,000 miles)more the satellites more accurate navigation is produced.
