BREEZE-M DEB

BREEZE-M DEB is a tracked piece of space debris attributed to Russia (CIS), launched on 2006-02-28 from Baikonur, Kazakhstan on the Arabsat 4A launch. With over 20 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 431 km and 11,007 km with an inclination of 51.4°. It travels at approximately 20,671 km/h (5.74 km/s), completing one full orbit every 3 hours 41 minutes — that’s roughly 6.53 orbits per day. Its orbital eccentricity of 0.4374 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. As orbital debris, BREEZE-M 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.

BREEZE-M DEB orbits at an average altitude of 5,719 km in Medium Earth Orbit, the region between LEO and GEO (2,000–35,786 km). MEO’s higher altitude gives each satellite a much larger ground footprint than LEO, meaning fewer spacecraft are needed for global coverage — but signal latency is higher and radiation from the Van Allen belts is a significant design constraint. Within ±50 km of BREEZE-M DEB’s average altitude, there are currently 0 active payloads and 6 tracked debris or rocket body fragments. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 51.4°, BREEZE-M DEB passes over latitudes between 51.4°N and 51.4°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. Russia (CIS) operates approximately 1,285 active satellites in total.
