OBJECT B

OBJECT B is an active satellite operated by Centispace (China), launched on 2026-06-17 from Jiuquan Satellite Launch Center, China on the Centispace 05 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. Independent catalogue analysis identifies this object as Centispace 05-02, attributed to Centispace. It orbits in Low Earth Orbit (LEO) at altitudes between 959 km and 969 km with an inclination of 55.1°. It travels at approximately 26,538 km/h (7.37 km/s), completing one full orbit every 104 minutes — that’s roughly 13.80 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks OBJECT B in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OBJECT B orbits at an average altitude of 964 km in the upper LEO band, where atmospheric drag is negligible and objects can persist for centuries to millennia. This altitude is used by broadband constellations like OneWeb and by scientific missions requiring stable orbits far from the densest debris bands. Within ±50 km of OBJECT B’s average altitude, there are currently 444 active payloads and 1,248 tracked debris or rocket body fragments. With an inclination of 55.1°, OBJECT B passes over latitudes between 55.1°N and 55.1°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. China operates approximately 1,650 active satellites in total, of which 72 share a similar altitude band with OBJECT B.
