   Strength of asteroidal rock...   
   02 Sep 17 21:54:36   
   
   Assume for a moment that an asteroidal object of metallic/rocky composition   
   were to exist in the shape of a doughnut/torus, with a radius of half a mile   
   _within_ the cylinder, that is, the 'ring' of the doughnut is 1 mile in   
   diameter from the inner rim    
   to the outer rim, and the hollow area in the middle is ~3.4 miles across.   
      
   What I'm trying to determine is if this could hold its shape against its own   
   feeble gravity over time, and if so, how much rotation could it handle before   
   it deformed out of the torus shape?
