A delightfully fun, fact-filled planetary tale from the creator of the Baby University series!

Travel around the solar system and celebrate what makes each planet unique! From Neptune to Mercury and all the planets in between, each one is different and each one is happy to be what they are.

Old slow Neptune looks a bit behind.
Orbiting the Sun takes an awful long time.
But the 8th little planet doesn't need to worry.
It spins on its axis in a really big hurry!

Vibrant, joyful art, playful verse, and a fun die-cut shape are sure to have astronomers of all ages celebrating their own uniqueness while they party with the planets.
