OBJECT B

OBJECT B (NORAD ID 69583) is a space object catalogued under China, launched on 2026-06-17 from Jiuquan, China on the Centispace 05 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 833 km and 846 km with an inclination of 55.1°. It travels at approximately 26,766 km/h (7.44 km/s), completing one full orbit every 102 minutes — that’s roughly 14.16 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 840 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 258 active payloads and 2,130 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0179, ONEWEB-0455. 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 1,217 active satellites in total, of which 121 share a similar altitude band with OBJECT B.
