BREEZE-M R/B

BREEZE-M R/B is a spent rocket body associated with Russia (CIS), launched on 2011-11-25 from Baikonur, Kazakhstan on the Asiasat 7 launch. After 15 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Medium Earth Orbit (MEO) at altitudes between 11,884 km and 34,302 km with an inclination of 1.5°. It travels at approximately 13,241 km/h (3.68 km/s), completing one full orbit every 13 hours 59 minutes — that’s roughly 1.72 orbits per day. Its orbital eccentricity of 0.3804 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 23,093 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 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 1.5°, BREEZE-M R/B passes over latitudes between 1.5°N and 1.5°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.
