   I seem to remember an article in S&T many years ago about the   
   brightness and UV exposure at various distances from the sun.  The   
   article said that the sun from Pluto would be about 250 times brighter   
   than the full moon from Earth.   
      
   If it were the angular size of Venus, it would be much brighter, as it   
   is a light source, whereas Venus is a reflector.
