📖 About This Object
COSMOS 952 is an active satellite operated by Russia (CIS), launched on 1977-09-16 from Baikonur, Kazakhstan. With over 49 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 922 km and 980 km with an inclination of 64.9°. It travels at approximately 26,562 km/h (7.38 km/s), completing one full orbit every 104 minutes — that’s roughly 13.84 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks COSMOS 952 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
COSMOS 952 occupies the mid-LEO band between 600 and 1,000 km, where atmospheric drag is minimal but radiation exposure remains low. This altitude range balances orbital longevity (decades to centuries) with reasonable ground coverage, making it popular for remote sensing constellations, scientific instruments and weather satellites. Debris concerns are significant here because objects persist far longer than in lower orbits.
❓ Frequently Asked Questions
COSMOS 952 orbits in Low Earth Orbit (LEO) at altitudes between 922 km (perigee) and 980 km (apogee), with an average altitude of approximately 951 km. It completes one orbit every 104 minutes, travelling at approximately 26,562 km/h (16,505 mph).
COSMOS 952 is operated by Russia (CIS). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 10358. You can track COSMOS 952 in real time on Orbital Radar’s live tracker.
COSMOS 952 was launched on 1977-09-16 from Baikonur, Kazakhstan, the world’s first and largest operational space launch facility, located in Kazakhstan. At its current altitude, the estimated remaining orbital lifetime is: ~100–500 years.
Yes — Orbital Radar tracks COSMOS 952 (NORAD ID 10358) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time.
COSMOS 952 travels at approximately 26,562 km/h (16,505 mph) — roughly 7.38 km/s. It completes 13.84 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 28 sunrises and sunsets every 24 hours.
