I believe that they are showing us the sun as the big circle,nibiru in the middle and Earth as a small onecheers!
This one is so simple. Maybe they have given up on us understanding the technical ones.
The two circles near the big one probably means we are going to have two suns in the near future. The date tht it was found is quite interesting too, 6/June(6)/2013(6) Hmmmmmm
