The sun, planets, moon, and other space objects are all part of our solar system.

Full-color photographs and fast facts illuminate this fascinating topic, while a Words to Know section and an entertaining activity reinforce new knowledge. This book correlates directly with the Next Generation Science Standards' expectation for understanding Earth's Place in the Universe in first and second grades. It is also aligned with English Language Arts standards.
