📖 About This Object
COSMOS 1867 is an active satellite operated by Russia (CIS), launched on 1987-07-10 from Baikonur, Kazakhstan. With over 39 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 776 km and 797 km with an inclination of 65.0°. It travels at approximately 26,865 km/h (7.46 km/s), completing one full orbit every 101 minutes — that’s roughly 14.32 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~25–100 years. Orbital Radar tracks COSMOS 1867 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 1867 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 1867 orbits in Low Earth Orbit (LEO) at altitudes between 776 km (perigee) and 797 km (apogee), with an average altitude of approximately 787 km. It completes one orbit every 101 minutes, travelling at approximately 26,865 km/h (16,693 mph).
COSMOS 1867 is operated by Russia (CIS). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 18187. You can track COSMOS 1867 in real time on Orbital Radar’s live tracker.
COSMOS 1867 was launched on 1987-07-10 from Baikonur, Kazakhstan, the world’s first and largest operational space launch facility, located in Kazakhstan. At its current altitude, the estimated remaining orbital lifetime is: ~25–100 years.
Yes — Orbital Radar tracks COSMOS 1867 (NORAD ID 18187) 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 1867 travels at approximately 26,865 km/h (16,693 mph) — roughly 7.46 km/s. It completes 14.32 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 29 sunrises and sunsets every 24 hours.
