About SHIYAN 2 (SY-2)
SHIYAN 2 (SY-2) is a satellite from China, launched on Nov 18, 2004 from Xichang Space Center, China.
It circles Earth every 98 minutes (14.7 times a day), between 665 and 679 km up, on an orbit tilted 98.1° to the equator, so its path covers latitudes up to 82° 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 24 days its lowest point went from 666 km to 665 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.
