About SIRIO

SIRIO is a satellite from Italy, launched on Aug 25, 1977 from Air Force Eastern Test Range.

It sits in geostationary orbit about 35,800 km above the equator near 74°E, turning with Earth so it stays over the same spot.

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 13 days its lowest point went from 35,764 km to 35,765 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
