The Earth is the third planet from the Sun, and the only place we know of so far that’s inhabited by living beings. Our planet is the 5th largest planet in the solar system and the only one with liquid water on the surface, although it is made mostly of rock and metal. Water covers 70% of Earth's surface.
The atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe. It also protects us from incoming meteoroids, most of which break up in our atmosphere before they can strike the surface as meteorites.
