How high is geosynchronous orbit?
A geosynchronous orbit is one in which an object orbits the Earth at the same speed as the Earth rotates. A geostationary orbit is a geosynchronous orbit in which an object stays above a fixed point on the Earth. According to NASA, a geostationary orbit can only occur at the Earth’s equator and requires an altitude of 35,00 kilometers (21,747 miles).Source:NASA Goddard Space Fligt Center: Ask an AstrophysicistU.S.
