Operators of Satellite constellations are constantly forced to move their satellites because of encounters with other spacecraft and pieces of space junk. And, thanks to SpaceX's Starlink satellites, the number of such dangerous approaches will continue to grow, according to estimates based on available data.
The starlink satellites are responsible for over 1,600 near collisions every week. Near collisions are when two spacecraft get within 1km of each other (0.6 miles).
But to make matters worse, SpaceX have only got 1,700 out of their 12,000 satellites in orbit, In the future we predict 90% of near collisions will be caused by the starlink satellites.
Starlink satellites have also been a cause of light pollution, which makes it harder to see stars and planets at night.
