OBJECT B

OBJECT B (NORAD ID 58850) is a space object catalogued under Iran, launched on 2024-01-28 from SEM on the Mehda launch. It orbits in Low Earth Orbit (LEO) at altitudes between 447 km and 1,045 km with an inclination of 58.7°. It travels at approximately 26,942 km/h (7.48 km/s), completing one full orbit every 100 minutes — that’s roughly 14.44 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~25–100 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 746 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 OBJECT B’s average altitude, there are currently 375 active payloads and 1,904 tracked debris or rocket body fragments — notable neighbours include LANDSAT 9. With an inclination of 58.7°, OBJECT B passes over latitudes between 58.7°N and 58.7°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. Iran operates approximately 5 active satellites in total.
