📖 About This Object
COSMOS 1045 is an active satellite operated by Russia (CIS), launched on 1978-10-26 from PKMTR. With over 48 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 1,685 km and 1,706 km with an inclination of 82.5°. It travels at approximately 25,306 km/h (7.03 km/s), completing one full orbit every 2 hours — that’s roughly 11.97 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks COSMOS 1045 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 1045 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.
🔗 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 1045 orbits in Low Earth Orbit (LEO) at altitudes between 1,685 km (perigee) and 1,706 km (apogee), with an average altitude of approximately 1,696 km. It completes one orbit every 2 hours, travelling at approximately 25,306 km/h (15,725 mph).
COSMOS 1045 is operated by Russia (CIS). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 11084. You can track COSMOS 1045 in real time on Orbital Radar’s live tracker.
COSMOS 1045 was launched on 1978-10-26 from PKMTR. At its current altitude, the estimated remaining orbital lifetime is: thousands of years.
Yes — Orbital Radar tracks COSMOS 1045 (NORAD ID 11084) 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 1045 travels at approximately 25,306 km/h (15,725 mph) — roughly 7.03 km/s. It completes 11.97 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 24 sunrises and sunsets every 24 hours.
