Then gravity would condense it all down into a planet in very short order, geologically speaking. For an example in our own system, see Saturn's rings.

- shiroiushi 2y agoGeologically speaking, sure. But humans don't live in geological timescales: it seems possible that, if humans could somehow explore other star systems on a regular basis, they might come across some systems where there was a relatively recent collision leaving lots of close-together asteroids that haven't yet had enough time to condense into a new body.
- adastra22 2y agoYes, like Saturn's rings.
- dotancohen 2y agoIf such collisions are common, then yes.
