Orbit size comparison of GPS, GLONASS, Galileo, BeiDou-2, and Iridium constellations, the International Space Station, the Hubble Space Telescope, and geostationary orbit (and its graveyard orbit), with the Van Allen radiation belts and the Earth to scale.[lower-alpha 1]Template:Paragraph The Moon's orbit is around 9 times as large as geostationary orbit.[lower-alpha 2] (In the SVG file, hover over an orbit or its label to highlight it; click to load its article.)

References

  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, approximately Template:Val; M, mass of Earth, approximately Template:Val.
  2. Approximately 8.6 times (in radius and length) when the moon is nearest (Template:Val ÷ Template:Val) to 9.6 times when the moon is farthest (Template:Val ÷ Template:Val).
