COSMOS 1867

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 775 km and 799 km with an inclination of 65.0°. It travels at approximately 26,864 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.

COSMOS 1867 orbits at an average altitude of 787 km in the mid-LEO band, where atmospheric drag is minimal but radiation exposure remains manageable. Objects at this altitude persist for decades to centuries, making debris mitigation critical. This regime is popular for remote sensing constellations and scientific instruments that need stable, long-duration orbits. Within ±50 km of COSMOS 1867’s average altitude, there are currently 418 active payloads and 2,224 tracked debris or rocket body fragments — notable neighbours include NOAA 20, ONEWEB-0179, ONEWEB-0455. With an inclination of 65.0°, COSMOS 1867 passes over latitudes between 65.0°N and 65.0°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. Russia (CIS) operates approximately 1,286 active satellites in total, of which 60 share a similar altitude band with COSMOS 1867.
