Overview
Earth orbit is loosely defined as any place far enough out of Earth's atmosphere so as to be able to circle Earth one or more times without being de-orbited by atmospheric drag (approx. 200 km or 120 miles) yet not so far away from Earth as to be more strongly influenced by other bodies such as Luna or Sol.
Earth orbit is generally divided into the following areas:
- low Earth orbit, or LEO
- geosynchronous Earth orbit, or GEO
- is there a term for orbits between GEO and the L-points?
- Earth-Luna L points (L1-L5)
Pages
- space-based solar power would most likely involve solar satellites in Earth orbit
