📖 About This Object
COSMOS 926 is an active satellite operated by Russia (CIS), launched on 1977-07-08 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 966 km and 1,015 km with an inclination of 82.9°. It travels at approximately 26,490 km/h (7.36 km/s), completing one full orbit every 105 minutes — that’s roughly 13.73 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks COSMOS 926 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 926 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 926 orbits in Low Earth Orbit (LEO) at altitudes between 966 km (perigee) and 1,015 km (apogee), with an average altitude of approximately 991 km. It completes one orbit every 105 minutes, travelling at approximately 26,490 km/h (16,460 mph).
COSMOS 926 is operated by Russia (CIS). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 10137. You can track COSMOS 926 in real time on Orbital Radar’s live tracker.
COSMOS 926 was launched on 1977-07-08 from PKMTR. At its current altitude, the estimated remaining orbital lifetime is: ~100–500 years.
Yes — Orbital Radar tracks COSMOS 926 (NORAD ID 10137) 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 926 travels at approximately 26,490 km/h (16,460 mph) — roughly 7.36 km/s. It completes 13.73 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 27 sunrises and sunsets every 24 hours.
