   	REALLY tiny. Do the calculations, dude, please. If I've got two months   
   before you hit me, and I do a jink, and let's say your KKV is an   
   asteroid 50 kilometers wide, my jink has to be an average of about ONE   
   cm/sec AVERAGE VELOCITY to ensure you miss -- even if my jink is in the   
   *exactly* wrong direction so I have to move a full 50 kilometers. That's   
   either a pretty damn tiny rocket burn for any station that's got any   
   stationkeeping ability at all, or 0.0000004 centimeters/sec^2   
   acceleration. That's 1/2,592,000,000 of a gravity.   
      
   	A solar sail the size of a *bedsheet* could manage that.
