COSMOS 2061

COSMOS 2061 is an active satellite operated by Russia (CIS), launched on 1990-03-20 from PKMTR. With over 36 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 969 km and 1,013 km with an inclination of 82.9°. It travels at approximately 26,489 km/h (7.36 km/s), completing one full orbit every 105 minutes — that’s roughly 13.72 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks COSMOS 2061 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 2061 orbits at an average altitude of 991 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 COSMOS 2061’s average altitude, there are currently 275 active payloads and 901 tracked debris or rocket body fragments. With an inclination of 82.9°, COSMOS 2061 passes over latitudes between 82.9°N and 82.9°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 1,285 active satellites in total, of which 154 share a similar altitude band with COSMOS 2061.
