About OAO 2

OAO 2 is a satellite from the United States, launched on Dec 7, 1968 from Air Force Eastern Test Range.

It circles Earth every 99 minutes (14.5 times a day), between 730 and 738 km up, on an orbit tilted 35.0° to the equator, so its path covers latitudes up to 35° 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 10 days its lowest point went from 731 km to 730 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
