What is Space Junk?

Space junk is the term used to describe man-made rubbish floating in space – often litter from space exploration, including spanners, nuts, bolts, gloves and shards of space craft.
The majority of the debris in space is believed to consist of small particles but some objects are larger, including spent rocket stages, defunct satellites and collision fragments.
As many as ten million pieces of human-made debris are estimated to be circulating in space at any one time.
Experts believe that global positioning systems, international phone connections, television signals and weather forecasts could be affected by increasing levels of space junk.
The windows of space shuttles are often chipped by space junk when returning to earth.
