Comparison of geostationary, GPS, GLONASS, Galileo, Compass (medium earth orbit), International Space Station, Hubble Space Telescope and Iridium constellation orbits, with the Van Allen radiation belts and the Earth.[lower-alpha 1] The Moon's orbit is around 9 times larger (in radius and length) than geostationary orbit.[lower-alpha 2] (In the SVG file, hover over an orbit or its label to highlight it, and click to load its article.)

  1. Orbital periods and speeds are calculated using the relations 4π²R³ = T²GM and V²R = GM, where R = radius of orbit in metres, T = orbital period in seconds, V = orbital speed in m/s, G = gravitational constant ≈ 6.673×1011 Nm²/kg², M = mass of Earth ≈ 5.98×1024 kg.
  2. Approximately 8.6 times when the moon is nearest (363 104 km ÷ 42 164 km) to 9.6 times when the moon is farthest (405 696 km ÷ 42 164 km).
