About POLAR BEAR
POLAR BEAR is a satellite from the United States, launched on Nov 14, 1986 from Air Force Western Test Range.
It circles Earth every 105 minutes (13.8 times a day), between 953 and 1,008 km up, on an orbit tilted 89.6° to the equator, so its path covers latitudes up to 90° 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 15 days its lowest point went from 953 km to 953 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.
