The large mass of the sun makes Earth move around it, just as the mass of Earth makes the moon move around it. Earth also turns around in space, so that different parts face the sun at different times. Earth goes around the sunonce (one "year") for every 365¼ times it turns all the way around (one "day").
Earth is the only planet in our solar system that has a large amount of liquid water.About 74% of the surface of Earth is covered by liquid or frozen water. Because of this, people sometimes call it "blue planet".
Because of its water, Earth is home to millions of species of plants and animals. The things that live on Earth have changed its surface greatly. For example, early cyanobacteria changed the air and gave it oxygen. The living part of Earth's surface is called the "biosphere".
