Space debris or space junk is the artificial material that is orbiting the earth but is no longer functional.
Most of these debris are in Low Earth orbit.
These debris can be as large as a rocket or as small as a chip.
These space debris are moving very fast.
Due to the high speed and volume of space debris, current and future space bound activities pose a safety risk to people and property in space and earth.
Currently there are no international law to clean up these debris.
Low Earth orbit is now considered as the world's largest garbage dump.
It is very expensive to remove the debris from the space
