Space Cake- rear

Here's my first display cake I made for the bakery. I included all the planets (including pluto because I love the wee planet!) in addition to some commets, stars and last but not least, Sputnik!
These tiers are a 6" 9" combo, covered in marbled black, turquoise, blue, and magenta fondant. For the stars, I diluted a bit of white food coloring and flicked/sprayed it on with a paint brush.
