METEOR 2-4

METEOR 2-4 is an active satellite operated by Russia (CIS), launched on 1979-03-01 from PKMTR. With over 47 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 834 km and 869 km with an inclination of 81.2°. It travels at approximately 26,744 km/h (7.43 km/s), completing one full orbit every 102 minutes — that’s roughly 14.12 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks METEOR 2-4 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

METEOR 2-4 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.
