>If you were on an asteroid it is extremely unlikely you could see another with your naked eye.

I remember science fiction shows when I was a kid, and they'd go through "The asteroid belt!!!' or a "meteor storm!!!" and were avoiding what looked like dozens of balls of crumpled-up foil, banging into their space ship. I think a lot of nerdy kids pictured the asteroid belt as a shotgun blast of planet chunks bouncing off each other. If one really want to bump into a lot of stuff in space, they might choose Saturn's rings though.
