Earth, our home, is the third planet from the sun. It is the only planet known to have an atmosphere containing oxygen, oceans of liquid water on its surface, and, of course, life.

Planet Earth is the fifth largest of the planets in the solar system — it is smaller than the four gas giants, Jupiter, Saturn, Uranus and Neptune, but it is larger than the three other rocky planets, Mercury, Mars and Venus.

Planet Earth has a diameter of roughly 8,000 miles (13,000 kilometers).​​​​​​​

Our world is moving constantly, spinning at a rate of 1,000 miles per hour. We are whirling around the sun at 20 miles per second. We, and our whole galaxy, are racing through space at more than a million miles an hour. The surface of our world is moving and changing, too.

The name Earth is at least 1,000 years old. All of the planets, except for Earth, were named after Greek and Roman gods and goddesses. However, the name Earth is an English/German word, which simply means the ground.
