Question

How Much Debris Is in Orbit?

To keep astronauts safe, scientists use radars to keep track of all the debris in orbit. They classify it by its size. About 13,000 known objects are bigger than 10 centimeters in diameter. Scientists believe that there are more than 100,000 pieces of orbital debris between 1 cm and 10 cm.

And tens of millions of pieces are smaller than 1 cm. All pieces of debris larger than 10 cm are carefully tracked using radars and telescopes. That information is used to estimate the number of small pieces of debris. Even though they cannot detect every piece, scientists have an idea of the amount of debris that is out there. [...]
