Introduction to the Solar System
Have you ever looked up at the sky and wondered what's out there? Our sky is a small window to a vast universe. And right in our neighborhood is our solar system - a big family of planets and stars! At the heart of this family is the Sun, a glowing ball of hot gas that is a star. Circling around the Sun are eight planets, including our Earth. Some planets, like Jupiter and Saturn, are giants made of gas. Others, like Mars and Venus, are rocky. Between Mars and Jupiter, there's a 'belt' of many small, rocky objects called asteroids. And don't forget the little dwarf planet, Pluto, living far out in the outskirts of this family. Isn't the solar system fascinating? But remember, it's just a tiny part of the universe. There is so much more for us to learn!
