70% of all catalogued objects are in low Earth orbit, as of Oct. 4, 2008, which extends to 2000 km above the Earth's surface. Note: The debris field shown in the image is an artist's impression based on actual data. However, the debris objects are shown at an exaggerated size to make them visible at the scale shown.
