Accu Says 47% of 33,269 Tracked Orbital Objects Are Junk
2 articles · Updated · Scientific American · May 13
17,682 of 33,269 tracked objects in Earth orbit are satellites, leaving nearly 47% classified as junk in Accu’s analysis of U.S. Space Force data.
10,000 more trackable objects were added between 2020 and 2025 as cheaper launches and a faster flight cadence sharply accelerated debris buildup.
17,000 mph orbital speeds make even tiny fragments dangerous, and Accu said the real share of inactive or uncontrollable objects is likely higher because many satellites no longer operate.
Seven tracked junk objects exist for every 10 satellites, making spacecraft the main target; recent incidents included ISS sheltering in 2024 and damage to a Tiangong return capsule in 2025.
65% of debris is attributed to China, with the U.S. at 40% and the CIS at 23%, as agencies and private firms pursue cleanup while engineers are urged to design for impacts.

With mega-constellations creating orbital traffic jams, is a catastrophic chain reaction of satellite collisions now inevitable?

Space Debris Crisis 2024: The Escalating Threat, Economic Impact, and Global Solutions for a Sustainable Orbit
Overview
Space debris is becoming an escalating threat, with recent incidents and a growing volume of orbiting fragments highlighting immediate risks to satellites, crewed missions, and the future of space exploration. This danger is fueled by continuous debris generation from mishaps with active satellites, disintegration of old spacecraft, and anti-satellite weapon tests, creating vast fields of debris that persist for years. The unpredictable nature of the space environment makes these risks even more serious, prompting urgent calls for increased international cooperation to address the problem and protect vital space activities.
