Space debris consists of defunct human-made objects in Earth orbit that no longer serve a useful function, ranging from tiny paint flecks to abandoned rocket bodies.
Scale and Population
Large objects (>10 cm): Over 31,000 tracked objects, including dead satellites and spent rocket stages.
Medium pieces (1–10 cm): Estimated 1.2 million fragments that are too small to track individually but dangerous.
Microscopic pieces (<1 cm): More than 140 million particles capable of causing severe damage upon impact.
Risks and Speed
Hypervelocity travel: Debris in low Earth orbit travels at roughly 17,500 mph (7.8 km/s), making even tiny fragments hit like a bullet or explosive.
Kessler Syndrome: A growing risk where a cascade of collisions generates continuous secondary fragments, potentially clogging useful orbital paths.
Operations: The International Space Station and operational mega-constellations frequently perform avoidance maneuvers to dodge catalogued junk.
Track space debris live across LEO, MEO and GEO. Explore fragmentation events, compare debris fields against active constellations, and monitor 31,000+ catalogued objects.
