About COSMOS 1903
COSMOS 1903 is a satellite from Russia (or the former Soviet Union), launched on Dec 21, 1987 from Plesetsk Missile and Space Complex.
It circles Earth every 717 minutes (2.0 times a day), between 8,490 and 31,833 km up, on an orbit tilted 69.0° to the equator, so its path covers latitudes up to 69° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
