Low earth orbit (LEO) is defined by two characteristics. First, an object in LEO has an orbital pattern that is earth-centric. This means that the object itself orbits earth (as opposed to the moon or another planet). Secondly, LEO is defined as having an altitude of less than 2000 km (1200 miles). Like all objects that orbit the earth (whether ...
