Is there an easy way to check if the bounding box of one model is intersecting the bounding box of any other model without moving the models?

I scripted an asteroid maker which randomly creates asteroids at random positions, but I don’t want any to overlap. So, when each is created I would like it to check to see if it touches another asteroid (or any other model), and if it does, just remove it. There has to be a pretty easy way to do this, but I can’t seem to wrap my mind around it.

Thanks for any help.
