METEOR 1-25

METEOR 1-25 is an active satellite operated by Priroda (Russia (CIS)), launched on 1976-05-15 from Plesetsk Cosmodrome, Russia on the Meteor-Priroda No. 2-1 launch. After more than 50 years in orbit, it is one of the longest-surviving objects in the space catalogue. It orbits in Low Earth Orbit (LEO) at altitudes between 825 km and 881 km with an inclination of 81.3°. It travels at approximately 26,741 km/h (7.43 km/s), completing one full orbit every 102 minutes — that’s roughly 14.12 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks METEOR 1-25 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

METEOR 1-25 orbits at an average altitude of 853 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 1-25’s average altitude, there are currently 260 active payloads and 2,304 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0455. With an inclination of 81.3°, METEOR 1-25 passes over latitudes between 81.3°N and 81.3°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 1,553 active satellites in total, of which 73 share a similar altitude band with METEOR 1-25.
