   Towing Asteroids by Gravity

   I'm intrigued as to why there are no references to the above in any of the   
   'space' newsgroups. Do you guys know something that the public doesn't? It   
   seemed such an interesting idea to me.   
   At risk of embarrassing myself before some clever people, I played with some   
   figures in a spreadsheet and was startled as to how little gravitational   
   attraction the '20 ton space craft' would have. But what if it had hydraulic   
   grabs (very long arms, to fragile to be deployed in Earth gravity) and   
   picked a rock from the asteroid mass of a few hundred tons?   
   Thoughts please.
