What’s the
solar system
? It’s our place in space.
The Sun is the star of our solar system. Its massive
gravity
pulls at eight planets, five dwarf planets, and millions of smaller
objects. Most of these objects—planets, comets, asteroids,
meteoroids
—move in circles around the Sun. But a few
orbit
nearby planets. They are called
moons
and
rings
.
As you read this book, you’ll learn all kinds of cool facts about
our solar system. But that’s not all. This book is also chock full of
jokes. Some of them will
make you laugh out loud.
Others might make you
groan. (Sorry.) But either
way, you’ll have a heck of
a good time. So let’s get
started!
Welcome to the
Solar System
