OBJECT F

OBJECT F (NORAD ID 63330) is a space object catalogued under Russia (CIS), launched on 2025-02-05 from Plesetsk Cosmodrome, Russia on the MKA-B 1 to 3 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. Independent catalogue analysis identifies this object as Kosmos-2583 subsatellite, attributed to MO RF. It orbits in Low Earth Orbit (LEO) at altitudes between 564 km and 582 km with an inclination of 82.0°. It travels at approximately 27,275 km/h (7.58 km/s), completing one full orbit every 96 minutes — that’s roughly 14.98 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks OBJECT F in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OBJECT F orbits at an average altitude of 573 km in the core of Low Earth Orbit, the most heavily utilised altitude band. The balance of moderate drag (limiting debris accumulation) and short signal path (enabling low-latency links and high-resolution imaging) makes this regime the default for most commercial and government missions. Within ±50 km of OBJECT F’s average altitude, there are currently 1,442 active payloads and 544 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-3005, STARLINK-3090. This makes it one of the more crowded altitude bands, containing roughly 7.7% of all active satellites. With an inclination of 82.0°, OBJECT F passes over latitudes between 82.0°N and 82.0°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. Russia (CIS) operates approximately 1,537 active satellites in total, of which 32 share a similar altitude band with OBJECT F.
