BREEZE-M R/B

BREEZE-M R/B is a spent rocket body associated with Russia (CIS), launched on 2013-04-15 from Baikonur, Kazakhstan on the Anik G1 launch. After 13 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Medium Earth Orbit (MEO) at altitudes between 7,921 km and 34,312 km with an inclination of 15.7°. It travels at approximately 13,709 km/h (3.81 km/s), completing one full orbit every 12 hours 36 minutes — that’s roughly 1.90 orbits per day. Its orbital eccentricity of 0.4801 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. 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 21,117 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 R/B’s average altitude, there are currently 0 active payloads and 25 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 15.7°, BREEZE-M R/B passes over latitudes between 15.7°N and 15.7°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.
