About COSMOS 637

COSMOS 637 is a satellite from Russia (or the former Soviet Union), launched on Mar 26, 1974 from Tyuratam Missile and Space Complex.

It sits in geostationary orbit about 35,800 km above the equator near 113°W, 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.

Over the last 12 days its lowest point went from 35,484 km to 35,483 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
