   Jupiter has more than 1000 times more deuterium than there is on Earth.   
   Saturn has about 300 times more.  The Sun has an amount that is more   
   than 7 times the total mass of Earth.   
      
   Sorry, still doesn't pass the giggle test.   
      
   And how much energy does it take to transport a kilo of deuterium across   
   interstellar space?
