NOTE: ‘ISS’ corresponds to: 400 km, ‘Sun-Synchronous’: 1 500 km, ‘Geostationary’: 36 000. ‘L2’ corresponds to the distribution at 1 AU without Earth attraction. The gravitational attraction of Earth shifts the distribution to higher velocities. Average velocities are: 22,7 km/s at 400 km, 21,7 km/s at 1 500 km, 18,8 km/s at 36 000 km and 17,2 km/s outside of the influence of Earth
