Comparison of GPS, GLONASS, Galileo and Compass (medium earth orbit satellites) satellite navigation system orbits with the International Space Station orbit, the Hubble Space Telescope orbit, Geostationary Earth Orbit and the nominal size of the Earth. The Moon's orbit is 9.1 times larger (in radius and length) than geostationary orbit.[1]
  1. Orbital periods are calculated using the relation 4π²R³=T²GM, where R = radius of orbit in metres, T = orbital period in seconds, G = gravitational constant ≈ 6.673×1011 Nm²/kg², M = mass of Earth ≈ 5.98×1024 kg.
