Our Home

Earth, the 3rd planet from the sun, is our home and as far as we know the only planet to host life. Earth is also the only planet with liquid water on the surface in our solar system. Earth is 1 AU (Astronomical Units) away from the sun and is the only planet not named after a Greek or Roman god or goddess. Earth is a rocky terrestrial planet like the other inner planets and has one moon.
