OBJECT BS

OBJECT BS (NORAD ID 43822) is a space object catalogued under Unknown, launched on 2018-12-03 from Vandenberg SFB, California on the SSO-A launch. It orbits in Low Earth Orbit (LEO) at altitudes between 517 km and 527 km with an inclination of 97.4°. It travels at approximately 27,376 km/h (7.60 km/s), completing one full orbit every 95 minutes — that’s roughly 15.15 orbits per day. Its near-polar, sun-synchronous orbit means it passes over any given point on Earth at approximately the same local solar time, ideal for consistent Earth observation lighting conditions. 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 ~3–10 years. Orbital Radar tracks OBJECT BS in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OBJECT BS orbits at an average altitude of 522 km in a sun-synchronous orbit (SSO), a specialised subset of LEO where the orbital plane precesses to maintain a constant angle relative to the Sun. This provides consistent lighting conditions on every pass — essential for Earth observation, weather monitoring and environmental science. Within ±50 km of OBJECT BS’s average altitude, there are currently 7,662 active payloads and 278 tracked debris or rocket body fragments — notable neighbours include STARLINK-1039, STARLINK-1184, STARLINK-1231. This makes it one of the more crowded altitude bands, containing roughly 44% of all active satellites. With an inclination of 97.4°, OBJECT BS passes over latitudes between 97.4°N and 97.4°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet.
