Geo space orbit?

It is a little strange that things in higher orbits actually travel more slowly than things in lower orbits. The Space Shuttle and the International Space Station both orbit in about 90 minutes, while the Moon - 250,000 miles away - take a whole month to orbit the earth.

There is one kind of orbit that has a special name and a special purpose. A satellite that orbits at 22,300 miles high will orbit the Earth in 24 hours. You might notice that the Earth revolves around its axis in 24 hours. So a satellite at that altitude orbits the Earth at the same rate that the Earth turns, which means that the satellite is moving just as fast as the Earth does. So the satellite appears to stand still in the sky!

We call this a geo-synchronous orbit. Geo, for Earth; synchronous, for "equal time". This is an especially handy orbit for things like communications satellites, which "hover" over the same spot on the equator.
