* Geostationary orbits are circular orbits around Earth at an altitude of approximately 35,786 kilometers (22,236 miles). A satellite in a geostationary orbit moves at the same rate as Earth's rotation, making it appear stationary from a point on Earth's surface.
* The Hubble Space Telescope orbits Earth at a much lower altitude of about 540 kilometers (335 miles). This lower altitude allows for much clearer and more detailed images.
Because of its lower orbit, Hubble does not stay in the same position relative to Earth. It continuously circles the planet, which is necessary for its scientific mission.
