ZQ-2E DEB

ZQ-2E DEB is a tracked piece of space debris attributed to China, launched on 2026-06-09 from Jiuquan, China on the Qianfan DTC1/ZYD-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 340 km and 432 km with an inclination of 54.5°. It travels at approximately 27,650 km/h (7.68 km/s), completing one full orbit every 92 minutes — that’s roughly 15.61 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is months to ~1 year. As orbital debris, ZQ-2E 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.

ZQ-2E DEB orbits at an average altitude of 386 km in the lower reaches of Low Earth Orbit, where atmospheric drag is significant and orbital lifetimes are measured in months to a few years. This is the busiest corridor in space — home to crewed spacecraft, rapid-revisit imaging satellites and the densest part of the Starlink constellation. Within ±50 km of ZQ-2E DEB’s average altitude, there are currently 1,281 active payloads and 70 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1020. This makes it one of the more crowded altitude bands, containing roughly 7.3% of all active satellites. With an inclination of 54.5°, ZQ-2E DEB passes over latitudes between 54.5°N and 54.5°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. China operates approximately 1,218 active satellites in total, of which 37 share a similar altitude band with ZQ-2E DEB.
