There are now millions of pieces of hazardous man-made debris in Earth orbit. From flecks of paint to defunct satellites, they travel faster than a bullet.

Even the tiniest pieces hitting a satellite can cause serious damage. In 2015 debris nearly forced the crew of the International Space Station to evacuate. Scientists are developing new telescopes to detect smaller fragments, but so far there's no easy way to get rid of them.

We urgently need to address this problem if we want satellites and space missions to keep working safely.

If the pieces that are spread are metallic, maybe using a magnet to bring them together would be an effective way to clean our orbit.
