That s the problem. There are a lot, but we are only going to explain a few.
Geosynchronous orbit is when a satellite stays in the same spot.
It is mostly used for weather reports, relaying signals, and air pollution alerts. This kind of orbit is very, very useful today. An elliptical orbit is the most natural orbit ever. Elliptical orbits may be caused by changes in the gravity of a planet. LEO is unnatural.
