Space Birthday Cake As requested by my son

My son had placed in his order more than half a year ago! He wanted the circle around the planet. I had to figure out how to meet up with the challenge :o) He was not happy with Santa upside down on the planet. He wanted the Christmas tree there too. Moist chocolate cake with melted and colored white chocolate circle. Buttercream 'soil'. Don't have a ball pan. Baked in 2 steel mixing bowls.
