I'd have thought they'd just burn up in the atmosphere as gravity pulled them down towards the Earth.

Long before most of you were born there was a 'needles' experiment, in which a load of copper needles were launched into orbit several thousand miles high in an attempt to make a reflector for radio communications.
People all shouted that they would block out the Sun and worse.
I think they dispersed quite soon.

They would remain close to the space ship as long as that space ship does not use power to change speed or direction.

Not if they were catapulted
