35 Earth, Moon, Sun, and Stars-High

Earth. Moon. Sun. and Stars Written by Alyse Sweeney

Introduction When we look up into the sky, we are looking into outer space. We can see the Sun, the Moon, and stars. They all seem to move very slowly across the sky. We live on a giant ball of rock and water called Earth. We don't see it because we live on it! It is also moving through space. It moves in a giant circle around the Sun.

The Moon is also a ball of rock, but it is smaller than Earth. The Moon moves in a giant circle around Earth. As Earth moves around the Sun, the Moon moves around Earth. Let's learn more about Earth, the Sun and stars, and the Moon. Let's learn about how they move through space.

Earth Earth is where we live. It is one of eight planets that go around the Sun. Earth is the third planet from the Sun. Being this far away keeps Earth from getting too hot or too cold. Planets closer to the Sun are so hot that steel would melt. Planets farther away are way too cold. Earth has the right amount of heat and light for plants and animals to live here.

Most of Earth is covered by water. Water is also below ground and in the air. That's why Earth is called the water planet. Living things need water to live. They also need air. Earth has a blanket of air around it. This blanket of air is called the atmosphere.

The Sun The Sun is just one of billions of stars in space. Like most stars, it is a giant ball of very, very hot gas. The Sun sends light to Earth. Light from the Sun hits Earth. It lets us see during the day. The light changes to heat when it hits Earth. The heat rises and warms Earth's atmosphere. Without the Sun, Earth would be dark, cold, and lifeless.
