GPS、GLONASS、Galileo、BeiDou-2和依衛星星座（英语：Iridium satellite constellation）、國際太空站、哈伯太空望遠鏡和地球靜止軌道（及其死亡軌道）的軌道大小比較，按比例計算范艾伦辐射带和地球[a]
月球的軌道大約是地球靜止軌道的9倍大[b]。 (In the SVG file, hover over an orbit or its label to highlight it; click to load its article.)

  1. ^ Orbital periods and speeds are calculated using the relations 4π2R3 = T2GM and V2R = GM, where R is the radius of orbit in metres; T is the orbital period in seconds; V is the orbital speed in m/s; G is the gravitational constant, approximately 6.673×10−11 Nm2/kg2; M is the mass of Earth, approximately 5.98×1024公斤（1.318×1025磅）.
  2. ^ Approximately 8.6 times (in radius and length) when the Moon is nearest (that is, 363,104 km/42,164 km), to 9.6 times when the Moon is farthest (that is, 405,696 km/42,164 km).
