This fun, kid-friendly science lesson is couched as a cute and lively friendship story between Earth and the moon. Author Stacy McAnulty's choice to make the moon the narrator is a clever one, as it draws kids in and sweeps them up in the moon's bubbly enthusiasm. And Stevie Lewis' cartoon-like illustrations are loaded with personality and expressiveness. To show the difference between the moon and Earth's size and strength of gravity, he portrays them wearing workout head- and wristbands and lifting weights. Earth easily lifts a long barbell overhead one-handed, while the moon struggles to raise one small free weight, with sweat beads flying off her forehead. (Earth is referred to as "she/her" throughout the book.)

Moon! Earth's Best Friend ends with a warm and comforting message to the reader: "Im always here for Earth. I'm always here for you. Where Earth goes, I go./ And where Earth goes, you go! Guess that makes us best friends, too."
