About TIANYAN 23
TIANYAN 23 is a satellite from China, launched on Mar 15, 2025 from Jiuquan Satellite Launch Center, China.
It circles Earth every 92 minutes (15.6 times a day), between 392 and 396 km up, on an orbit tilted 97.4° to the equator, so its path covers latitudes up to 83° 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 13 days its lowest point went from 395 km to 392 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.
