It won't be centuries.
starlink satellites are in low orbits and will deorbit in a few years at most if bricked; to stay in orbit, they use ion thrusters to counter drag from the very uppermost reaches of the atmosphere.

- titzer 2mo agoWhen satellites smash into each other at high velocity, they explode. Some of that debris will end up in higher orbits and linger.
- Polizeiposaune 2mo agoSome of the debris from a collision may end up in an orbit with a higher apogee, perigee will necessarily still be at or below the altitude of the last collision and will be subject to some of the same low-orbit aerodynamic drag that starlink satellites experience; passes through lower altitudes will apply drag that will first drop the apogee and will then eventually cause the debris to reenter.
- audunw 2mo agoHow can it linger in a higher orbit. Maybe some of the debris gets a kick which increases its velocity, but you need two velocity boosts to circularise the orbit, no? So I figure at worst you get an elliptical orbit which will still decay
- moralestapia 2mo agoNope, if it goes up it will go down even faster. Orbits are about speed. Two things colliding cannot have debris coming out at a faster velocity than either of them.
