Mir completes one orbit every 92 minutes 26 seconds and reaches latitudes between 51.65 degrees north and 51.65 degrees south. Hubble orbits once every 96 minutes 35 seconds and reaches latitudes lower than 28.47 degrees. Map generated by "OrbiTrack'' version 2.1.4 with NASA orbital elements set 795.
