1 cm, revolving around the learth! All this is nothing but the debris in space.
g
This debris can be aharmful to the artificial satellites. It can collide with
these satellites or spacecrafts and damage them. This debris is increasing day
by day. Soon, it will be difficult to launch new spacecrafts. It is, therefore,
very essential to manage the debris. Some studies and experiments are being
done with this in view.
