[The Expanse] If a ring shared an orbit with a planet, what would happen when they collided?
gpt
The rings are all positioned close to the outer edges of their solar systems, away from large concentrations of matter and near the top of the star's gravity well.

Since the rings seem to have existed in those positions for over a billion years (give or take), it seems logical that they have some way to handle potential collisions.

I suspect that if a massive object approached a ring, the ring would use intertialess propulsion (like Eros) to move out of the way and then return to its original position.

The alternative is that there used to be a *lot* more ring gates, and the 1,300 or so that remain are the lucky few that survived in especially empty or stable systems.
