COSMOS 2489

COSMOS 2489 is an active satellite operated by Ministry of Defense (Russia (CIS)), launched on 2013-12-25 from PKMTR. After 13 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 1,477 km and 1,512 km with an inclination of 82.5°. It travels at approximately 25,628 km/h (7.12 km/s), completing one full orbit every 116 minutes — that’s roughly 12.43 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks COSMOS 2489 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

COSMOS 2489 orbits at an average altitude of 1,495 km in the uppermost reaches of Low Earth Orbit. At this altitude, orbital decay is effectively zero without active deorbiting, and coverage footprints are significantly larger than lower LEO, though at the cost of higher latency. Within ±50 km of COSMOS 2489’s average altitude, there are currently 252 active payloads and 245 tracked debris or rocket body fragments. With an inclination of 82.5°, COSMOS 2489 passes over latitudes between 82.5°N and 82.5°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 244 share a similar altitude band with COSMOS 2489.
