Understanding Space Debris
Space debris measures the amount of human-made objects orbiting Earth. Over 36,500 objects larger than 10cm are tracked. Our debris counter trackstracked objects, collision risks, and Kessler syndrome.
Also known as space junk, orbital debris, and space trash, this metric is closely related to satellite safety, space exploration, and ISS operations.
Our space debris data covers multiple dimensions including by size, by orbit (LEO, GEO), sources, and collision history.
