METEOR 1-17 DEB

METEOR 1-17 DEB is a tracked piece of space debris attributed to Russia (CIS), launched on 1974-04-24 from PKMTR on the Meteor-M No. 22 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 793 km and 821 km with an inclination of 81.2°. It travels at approximately 26,827 km/h (7.45 km/s), completing one full orbit every 101 minutes — that’s roughly 14.25 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. As orbital debris, METEOR 1-17 DEB poses a potential collision risk to operational satellites in nearby orbits and is continuously monitored by the U.S. Space Surveillance Network and other tracking systems.

METEOR 1-17 DEB orbits at an average altitude of 807 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 1-17 DEB’s average altitude, there are currently 439 active payloads and 2,284 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0179, ONEWEB-0455. With an inclination of 81.2°, METEOR 1-17 DEB 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 1,285 active satellites in total, of which 86 share a similar altitude band with METEOR 1-17 DEB.
