About ALEXIS

ALEXIS is a satellite from the United States, launched on Apr 25, 1993 from Air Force Western Test Range.

It circles Earth every 100 minutes (14.3 times a day), between 736 and 823 km up, on an orbit tilted 69.9° to the equator, so its path covers latitudes up to 70° 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 19 days its lowest point went from 737 km to 736 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
