- Space debris accounts for 47% of known orbiting objects, about 12,550 uncontrolled pieces.
- Debris orbits at 17,400 mph, posing collision risks; even tiny pieces can damage spacecraft.
- China, the U.S., and CIS contribute most debris, with 34% and 31% shares respectively.
- Decaying orbits lead to atmospheric re-entry, but harmful particulates like aluminum remain in the atmosphere, affecting the ozone.
- Few projects exist to remove debris; ESA's ClearSpace-1 and private companies are exploring solutions like robotic arms and harpoons.
- Current space junk weighs around 15,550 tons, increasing without international coordination for cleanup.
