CZ-6A DEB

CZ-6A DEB is a tracked piece of space debris attributed to China, launched on 2025-05-11 from Taiyuan, China on the Yaogan 40-02 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 791 km and 811 km with an inclination of 86.0°. It travels at approximately 26,838 km/h (7.46 km/s), completing one full orbit every 101 minutes — that’s roughly 14.27 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. As orbital debris, CZ-6A 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.

CZ-6A DEB orbits at an average altitude of 801 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 CZ-6A DEB’s average altitude, there are currently 442 active payloads and 2,252 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0179, ONEWEB-0455. With an inclination of 86.0°, CZ-6A DEB passes over latitudes between 86.0°N and 86.0°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. China operates approximately 1,217 active satellites in total, of which 106 share a similar altitude band with CZ-6A DEB.
