Animals in the Sky by Sara Gillingham (ages 4 – 8)
Riddles help kids learn the constellations by their shapes with lift-the-flap answers and that give the answer and more information. “I have a big bushy mane, a long tail, and a loud roar. I am the king of the jungle! What animal in the sky am I? I am the Lion. My brightest star is called Regulus, which means “little king.”” The white and gold text and illustrations pop out off the page set onto turquoise and navy blue backgrounds.

XO, Exoplanet by Deborah Underwood, illustrated by Jorge Lacera (ages 4 – 8)
Get ready to laugh at this hysterical story with a poignant message about seeing multiple perspectives! When our solar system’s planets write a friendly letter to an exoplanet, their communication turns into a funny argument when the exoplanet tells our planets that THEY are the exoplanets.

The story skillfully entertains while educating readers about Pluto and other solar system elements. Great artwork throughout this fantastic, emotionally resonate story.

Mars is a planet with a big personality. In first-person narration, Mars shares all its many features that are much better than Earth’s. Like two moons and 37 more minutes in a day!

Written directly to the reader (you), this book gives you instructions for what to pack and expect if you travel to the moon.
