Trackable space debris. Computer artwork showing the trackable space debris in low Earth orbit (LEO, up to 2000 kilometres altitude) and geostationary Earth orbit (GEO, around 35, 700 kilometres altitude). The debris is trackable if it is larger than 15 centimetres in diameter. Space debris includes thousands of inactive satellites, fragments of broken up spacecraft and equipment lost by astronauts. This artwork is based on density data, , but the debris is not to scale. For an image including untrackable debris see S800/038. *** THIS PICTURE MAY NOT BE USED TO STATE OR IMPLY ESA ENDORSEMENT OF ANY COMPANY OR PRODUCT ***.
