About COSMOS 2155

COSMOS 2155 is a satellite from Russia (or the former Soviet Union), launched on Sep 13, 1991 from Tyuratam Missile and Space Complex.

It sits in geostationary orbit about 35,800 km above the equator near 176°E, turning with Earth so it stays over the same spot.

The map shows where it is right now; the pass list tells you when it next comes over your location.

Orbit height over the past year

Over the last 17 days its lowest point went from 35,775 km to 35,774 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
