'Space debris' orbits Earth

Objects in orbit around Earth

Between the launch of Sputnik in 1957 and 2008, around 6,000 satellites have been launched into orbit. These computer-generated photos show all the junk orbiting Earth.

It's estimated that only 800 satellites are working. The debris also includes hundreds of bits of space shuttles that have exploded, broken off or been abandoned.

Debris in low-Earth orbit

Eighty per cent of all space junk is around 1,200 miles above Earth or in low-Earth orbit (LEO). Spacecraft have to orbit at low altitude to avoid all the debris.
