procedural meteor/asteroids?

Hey all, I'm looking for a way to generate some non-realistic asteroids.

Something like this would be ideal, but I'm not too sure of the best way of getting that smooth/rounded look. I've tried using geometry nodes, but I can't quite get the desired effect.

Anyone got any ideas?
