📖 About This Object
COSMOS 1420 is an active satellite operated by Russia (CIS), launched on 1982-11-11 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 762 km and 790 km with an inclination of 74.0°. It travels at approximately 26,885 km/h (7.47 km/s), completing one full orbit every 100 minutes — that’s roughly 14.35 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~25–100 years. Orbital Radar tracks COSMOS 1420 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 1420 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 1420 orbits in Low Earth Orbit (LEO) at altitudes between 762 km (perigee) and 790 km (apogee), with an average altitude of approximately 776 km. It completes one orbit every 100 minutes, travelling at approximately 26,885 km/h (16,706 mph).

COSMOS 1420 was launched on 1982-11-11 from PKMTR. At its current altitude, the estimated remaining orbital lifetime is: ~25–100 years.
Yes — Orbital Radar tracks COSMOS 1420 (NORAD ID 13648) 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 1420 travels at approximately 26,885 km/h (16,706 mph) — roughly 7.47 km/s. It completes 14.35 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 29 sunrises and sunsets every 24 hours.
