Low Earth orbit
May 28, 2022
The low Earth orbit (NZO) is, as its name suggests, the lowest viable orbit around the Earth. The NZO starts at 160 km (when objects slow down due to the resistance of small amounts of air atoms still present, as at the International Space Station), and ends at about 2,000 km. and the record height of the apogee is held by the aircraft Gemini 11 with 1,374.1 km. The International Space Station has an average apogee and perigee between 330 and 435 km.
