OBJECT D

OBJECT D (NORAD ID 58428) is a space object catalogued under Russia (CIS), launched on 2023-10-27 from PKMTR on the Lotos-S1 No. 808? launch. It orbits in Low Earth Orbit (LEO) at altitudes between 890 km and 916 km with an inclination of 67.2°. It travels at approximately 26,649 km/h (7.40 km/s), completing one full orbit every 103 minutes — that’s roughly 13.97 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks OBJECT D in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OBJECT D orbits at an average altitude of 903 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 D’s average altitude, there are currently 213 active payloads and 1,307 tracked debris or rocket body fragments. With an inclination of 67.2°, OBJECT D passes over latitudes between 67.2°N and 67.2°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. Russia (CIS) operates approximately 1,285 active satellites in total, of which 52 share a similar altitude band with OBJECT D.
