This puzzle isn't very big.  You've only got the 9 planets to find.  However, you've got to find them backwards.  For example, you won't find mars, but you will find sram.  Gee, it might take you a few hours just to figure out how to spell all 9 planets backwards!  Oh, and Pluto's in there.  You heard me, I'm not ready to kick that little bugger out of the solar system just yet.
