METEOR 2-3

METEOR 2-3 is an active satellite operated by Russia (CIS), launched on 1977-12-14 from PKMTR. With over 49 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 839 km and 872 km with an inclination of 81.2°. It travels at approximately 26,737 km/h (7.43 km/s), completing one full orbit every 102 minutes — that’s roughly 14.11 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks METEOR 2-3 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

METEOR 2-3 orbits at an average altitude of 856 km in the upper LEO band, where atmospheric drag is negligible and objects can persist for centuries to millennia. This altitude is used by broadband constellations like OneWeb and by scientific missions requiring stable orbits far from the densest debris bands. Within ±50 km of METEOR 2-3’s average altitude, there are currently 260 active payloads and 1,974 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0179, ONEWEB-0455. With an inclination of 81.2°, METEOR 2-3 passes over latitudes between 81.2°N and 81.2°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. Russia (CIS) operates approximately 1,286 active satellites in total, of which 57 share a similar altitude band with METEOR 2-3.
