From the creator of the Baby University series and the team behind the adorably popular 8 Little Planets comes a new tale about the planet who no longer fits in. Pluto the planet was really quite proud. But at the party of planets, it wasn't allowed... OH NO! There are three rules a planet must follow, and Pluto breaks them all. It just doesn't fit in! Pluto is sad to no longer be an official planet. But with the help of some friends, Pluto might find its place in space again! With vibrant, joyful art, playful verse, and a fun die-cut shape, astronomers of all ages will love this celebration of our solar system's first minor planet in this delightfully fun, fact-filled planetary tale!
