📖 About This Object
COSMOS 1375 is an active satellite operated by Russia (CIS), launched on 1982-06-06 from PKMTR. With over 44 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 928 km and 965 km with an inclination of 65.8°. It travels at approximately 26,570 km/h (7.38 km/s), completing one full orbit every 104 minutes — that’s roughly 13.85 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks COSMOS 1375 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 1375 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.
🔗 Cosmos (Military/Government) Series
This satellite carries the Cosmos designation, used by Russia (and formerly the Soviet Union) as a generic identifier for military and government spacecraft. The Cosmos series encompasses reconnaissance, signals intelligence (SIGINT), early warning, navigation, communications and scientific payloads. Many Cosmos satellites have classified missions with limited publicly available information.
❓ Frequently Asked Questions
COSMOS 1375 orbits in Low Earth Orbit (LEO) at altitudes between 928 km (perigee) and 965 km (apogee), with an average altitude of approximately 947 km. It completes one orbit every 104 minutes, travelling at approximately 26,570 km/h (16,510 mph).

COSMOS 1375 was launched on 1982-06-06 from PKMTR. At its current altitude, the estimated remaining orbital lifetime is: ~100–500 years.
Yes — Orbital Radar tracks COSMOS 1375 (NORAD ID 13259) 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 1375 travels at approximately 26,570 km/h (16,510 mph) — roughly 7.38 km/s. It completes 13.85 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 28 sunrises and sunsets every 24 hours.
