ARIANE 5 R/B

ARIANE 5 R/B is a spent rocket body associated with France, launched on 2019-06-20 from Guiana Space Centre, French Guiana on the T-16/Eutelsat 7C launch. It orbits in Medium Earth Orbit (MEO) at altitudes between 239 km and 31,302 km with an inclination of 5.5°. It travels at approximately 15,275 km/h (4.24 km/s), completing one full orbit every 9 hours 7 minutes — that’s roughly 2.63 orbits per day. Its orbital eccentricity of 0.7015 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. Spent rocket bodies like ARIANE 5 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.

ARIANE 5 R/B orbits at an average altitude of 15,771 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 ARIANE 5 R/B’s average altitude, there are currently 1 active payload 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 5.5°, ARIANE 5 R/B passes over latitudes between 5.5°N and 5.5°S, concentrating coverage over equatorial and near-equatorial regions. Low-inclination orbits maximise revisit rates over specific tropical zones. France operates approximately 120 active satellites in total.
