NO! they just are up there floating around they are not large enough to have an orbit.
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
voyager Explorer 1 was the first US satellite to orbit the earth. It was proceeded by two Soviet Sputnik satellites.
well, some people say that the earth orbits us but it doesn't. Things don't orbit us because we are on the earth and the earth orbits the sun. The moon, however, does orbit the Earth, as well as any satellites we put into orbit.
There are currently 30 healthy GPS satellites in orbit.
Satellite orbit the Earth at different altitudes. A good overview of Low Earth Orbit, Medium Earth Orbit and Geostationary Orbit can be found here: http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
There are a great number of satellites currently orbiting the Earth, and they are ALL important; at least, important enough to SOMEBODY to spend millions of dollars to launch each one.Depending on your interests, the "most important" satellites are probably the weather forecasting satellites, followed by the communications and GPS satellites.

Gravity. A natural satellite aka asteroid, then meteor, then meteorite all get pulled to Earth through gravity. With artificial sattelites it's tge same thing, gravity. The difference is we launch our satellites to the perfect zone around the planet where they become trapped in orbit around us. Sometimes things occur that bump these satellites out of their orbit and gravity takes over, pulling the satellite back to the surface.
The sun doesn't orbit anything, the planets orbit the sun, and our moon orbits us. It takes 24 hours forthe moon to orbit us once and 365 days for the earth to orbit the sun once
GPS satellites orbit the earth, around 20,000Kms above us. They contain very precise atomic clocks which they use to produce a special timing signal which is then broadcast back to earth. Back on earth, we can use our GPS receivers (Like Sat Nav) to pick up the GPS signals, and by using very clever mathematical algorithms in conjunction with the timing signals we receive from the satellites, calculate our position on the surface of the earth.
The global positioning system is the network of satellites that orbit earth that gives us GPS
There are over 1000 operational satellites orbiting the Earth, and probably 10,000 pieces of "space junk" also orbiting the Earth.
