BREEZE-M R/B

BREEZE-M R/B is a spent rocket body associated with Russia (CIS), launched on 2014-12-15 from Baikonur, Kazakhstan on the Yamal-401 launch. After 12 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Medium Earth Orbit (MEO) at altitudes between 30,346 km and 35,544 km with an inclination of 8.7°. It travels at approximately 11,463 km/h (3.18 km/s), completing one full orbit every 21 hours 33 minutes — that’s roughly 1.11 orbits per day. Spent rocket bodies like BREEZE-M R/B are among the largest pieces of uncontrolled space debris and are priority targets for collision avoidance manoeuvres and future active debris removal efforts.

BREEZE-M R/B orbits at an average altitude of 32,945 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. With an inclination of 8.7°, BREEZE-M R/B passes over latitudes between 8.7°N and 8.7°S, concentrating coverage over equatorial and near-equatorial regions. Low-inclination orbits maximise revisit rates over specific tropical zones. Russia (CIS) operates approximately 1,286 active satellites in total.
