IRIDIUM 33 DEB, 46435

Orbit data source: Space-Track

IRIDIUM 33 DEB, 46435 is space debris in LEO originally from a launch on Sun, 14 Sep 1997 UTC launched from the Tyuratam Missile And Space Complex (TTMTR). The debris from Iridium 33, an American commercial communications satellite, has been tracked extensively since its accidental collision with the defunct Russian satellite Cosmos 2251 in 2009. This event, occurring at high speed in low Earth orbit (LEO), generated thousands of pieces of space debris, significantly increasing the risk of further collisions. The Iridium 33 debris cloud has impacted space traffic management and orbital debris mitigation strategies, making it a subject of ongoing study in space situational awareness.
