About COSMOS 2531
COSMOS 2531 is a satellite from Russia (or the former Soviet Union), launched on Nov 30, 2018 from Plesetsk Missile and Space Complex.
It circles Earth every 116 minutes (12.4 times a day), between 1,481 and 1,508 km up, on an orbit tilted 82.5° to the equator, so its path covers latitudes up to 83° north and south.
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 21 days its lowest point went from 1,481 km to 1,481 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
From Space-Track element sets, one point a day.
