CENTISPACE-2 S10

CENTISPACE-2 S10 is an active satellite operated by China, launched on 2026-03-22 from YSLA on the Weili Kongjian 02 zu 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 726 km and 739 km with an inclination of 55.0°. It travels at approximately 26,967 km/h (7.49 km/s), completing one full orbit every 99 minutes — that’s roughly 14.48 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 ~25–100 years. Orbital Radar tracks CENTISPACE-2 S10 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

CENTISPACE-2 S10 orbits at an average altitude of 733 km in the mid-LEO band, where atmospheric drag is minimal but radiation exposure remains manageable. Objects at this altitude persist for decades to centuries, making debris mitigation critical. This regime is popular for remote sensing constellations and scientific instruments that need stable, long-duration orbits. Within ±50 km of CENTISPACE-2 S10’s average altitude, there are currently 368 active payloads and 1,859 tracked debris or rocket body fragments — notable neighbours include TERRA, AQUA, LANDSAT 9. With an inclination of 55.0°, CENTISPACE-2 S10 passes over latitudes between 55.0°N and 55.0°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. China operates approximately 1,246 active satellites in total, of which 57 share a similar altitude band with CENTISPACE-2 S10.
