Thanks! Yes it is very simple, it is a bit tough to make an actual asteroid system work however.. The only thing that bothers me is the glitchy collider behaviour. As you can see, when the objects get closer, the gravitational force increases and colliders start pressing against each other quite hard. Colliders apparently don’t like that too much (not sure why) and sometimes behave strangely, but the simulation keeps on working fine. Also, as you said, it is just something to mess around with, nothing serious with objectives or missions.
