📖 About This Object
COSMOS 940 is an active satellite operated by Russia (CIS), launched on 1977-08-24 from PKMTR. With over 49 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 1,393 km and 1,462 km with an inclination of 74.0°. It travels at approximately 25,737 km/h (7.15 km/s), completing one full orbit every 114 minutes — that’s roughly 12.59 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks COSMOS 940 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 940 orbits in the upper reaches of Low Earth Orbit, above 1,000 km. At this altitude, atmospheric drag is negligible and objects can remain in orbit for thousands of years without active deorbiting. This region is used by satellite broadband constellations like OneWeb and by scientific missions that need stable, long-duration orbits away from the densest debris bands. The high inclination typical at this altitude provides near-global coverage.
❓ Frequently Asked Questions
COSMOS 940 orbits in Low Earth Orbit (LEO) at altitudes between 1,393 km (perigee) and 1,462 km (apogee), with an average altitude of approximately 1,428 km. It completes one orbit every 114 minutes, travelling at approximately 25,737 km/h (15,993 mph).

COSMOS 940 was launched on 1977-08-24 from PKMTR. At its current altitude, the estimated remaining orbital lifetime is: thousands of years.
Yes — Orbital Radar tracks COSMOS 940 (NORAD ID 10286) 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 940 travels at approximately 25,737 km/h (15,993 mph) — roughly 7.15 km/s. It completes 12.59 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 25 sunrises and sunsets every 24 hours.
