What Is the Solar System?

• The Solar System is a giant neighborhood in space where we live.
• It is made up of the Sun and everything that travels around it.
• Our home, Earth, is just one small part of this big family in the sky.

The Sun: Our Big Star

• The Sun is a massive, glowing ball of fire at the very center of our Solar System.
• It is a star that gives us light and warmth so plants can grow and we can see.
• Everything in the Solar System stays together because of the Sun's strength.

The Eight Planets

• There are eight planets that circle around the Sun in a path called an orbit.
• Some planets are small and rocky like Earth, while others are giant and made of gas.
• Mercury is the closest to the Sun, and Neptune is the farthest away in the cold dark.

Planet Earth: Our Special Home

• Earth is the third planet from the Sun and is the only one known to have life.
• It has plenty of water to drink and air for us to breathe.
• Earth is often called the "Blue Planet" because so much of it is covered in oceans.

The Moon and the Stars

• The Moon is Earth's best friend and travels around our planet every night.
• It does not have its own light; it reflects the light from the Sun like a mirror.
• At night, we see thousands of other stars that are very far away in space.

Lesson Summary

• The Solar System consists of the Sun, eight planets, and the Moon.
• The Sun is the center and provides the energy we need to live.
• Every planet is unique, but Earth is the most special because it is our home.
