How Many Planets Circle the Sun?: And Other Questions about Our Solar System (Good Question!) is a great book to learn about the solar system. Most of my kids questions got answered with this book. There are questions like: Why is there life on earth, how did Saturn get its rings, which planet is biggest, which one’s hottest—and which has a cloud named Scooter? Not only will they learn about planets like Earth, Mars, Jupiter, and Saturn, but they will learn about the asteroid belt, Martian volcanoes, dwarf planets, and other fascinating facts about our universe.
This is a great book for all those kid questions wondering “why” about our solar system. 🙂
Learning about space and the solar system was both my favorite topic to learn as well as teach!
