Every foil wrapped turd in space is in theory a kinetic impactor by value of location and acceleration.

There was a scifi short story, were a system was wrecked, aeons after a war, by what was essentially missed shots.

This is what makes the expanse so creepy. Every PDC round not finding a target- finds a target eventually. On the other side of the system, totally not intended, but it finds one. Even thinks doing the marathon with ion-engines can become lethally over time.

Voyager is another systems bullet.
