   So, I asked a question on Quora lately about it, but did not get any   
   satisfying answers yet, so I bring it here, for more professional look.   
   We all know that asteroid belts from movies are complete BS, but, I was   
   thinking if there could temporarily exist a cluster of small planetoids, in   
   which standing on one of them, you actually can see others, at let's say a few   
   kilometers distance.   
   I want to put such thing on orbit of my setting's main planet, and I don't   
   know how plausible is it. In my fantasy-sf world, such cluster is used as a   
   hub for further space travel and material base for creating spaceships.   
   Also, I want to know how long such thing could survive, even if it's short, a   
   few thousands years time, and it would be nice if someone could tell me if   
   that would be stable or would spit planetoids in all directions.
