About TIANQI 21
TIANQI 21 is a satellite from China, launched on Sep 5, 2023 from Yellow Sea Launch Area, China.
It circles Earth every 101 minutes (14.2 times a day), between 805 and 824 km up, on an orbit tilted 50.0° to the equator, so its path covers latitudes up to 50° 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 17 days its lowest point went from 805 km to 805 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.
