Space junk--or orital debris-- is anything human-made that is no longer useful. NASA tracks more than 500,000 pieces of debris because even something as little as a paint chip traveling at speeds up to 17,500 mph can be dangerous.

Right! They (NASA?) are experimenting with using a solar sail to scoop up the detritus.
We are such slobs!
