String of satellites baffles residents, bugs astronomers

8. Orbital pollution is a dangerous gamble

These close encounters already occur thousands of times each year, but the sheer vastness of mega constellations such as Starlink will change the game, resulting in an estimated 67,000 annual collision-avoidance maneuvers if all of them are launched. As Earth orbit becomes jam-packed with satellites, the risk increases. A worst-case scenario would be the Kessler syndrome, a positive feedback loop in which debris-generating collisions create more and more collisions, which in turn create more and more debris, rendering parts of Earth orbit essentially unusable.
