Comparison of GPS, GLONASS, Galileo and Compass (medium earth orbit) satellite navigation system orbits with the International Space Station, Hubble Space Telescope and Iridium constellation orbits, Geostationary Earth Orbit, and the nominal size of the Earth.[lower-alpha 1] The Moon's orbit is around 9 times larger (in radius and length) than geostationary orbit.[lower-alpha 2]
