METEOR 1-18

METEOR 1-18 is an active satellite operated by Priroda (Russia (CIS)), launched on 1974-07-09 from Plesetsk Cosmodrome, Russia on the Meteor-Priroda No. 1 launch. After more than 52 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 880 km and 906 km with an inclination of 81.2°. It travels at approximately 26,668 km/h (7.41 km/s), completing one full orbit every 103 minutes — that’s roughly 14.00 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks METEOR 1-18 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

METEOR 1-18 orbits at an average altitude of 893 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 1-18’s average altitude, there are currently 262 active payloads and 1,788 tracked debris or rocket body fragments. With an inclination of 81.2°, METEOR 1-18 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 1,553 active satellites in total, of which 80 share a similar altitude band with METEOR 1-18.
