Beyond the Sky by ANNA PROKOS With the Editors of TIME FOR KIDS

Chapter 1 Look at the Sky! Look at the sky. What do you see? In the day, you see the sun. At night, you see the moon and stars. Our solar system has the Sun, the Moon, and stars. It also has eight planets. Earth is the only planet with plants and animals. Living things need the right mix of gases and water. Earth has the right mix.

Chapter 2 Earth Goes Around the Sun The center of the solar system is the Sun. Earth goes around the Sun in a circle. This is called an orbit. Earth spins at the same time it goes around the Sun. Does Earth spin? How do you know? Look at the sky. Does the Sun move? The Sun, Moon, and stars look like they move across the sky. But Earth is what really moves!

Chapter 3 Where is the Sun? Where is the Sun? In the morning, we see the Sun down low in the sky. At midday, it is high in the sky. In the evening, it is low again. At night, we cannot see the Sun. When Earth spins, sometimes your place on Earth is near the Sun. It is day. Sometimes your place on Earth is far from the Sun. It is night. Earth does not stop spinning. Soon you are near the Sun again. It is day again!

Chapter 4 Look at the Stars! There are millions of stars in space. We can only see a thousand stars. The other stars are too far away. We need a telescope to see them. A star is a big ball of burning gas. When the gas burns, the star makes heat and light. The Sun is a star. The Sun is close to Earth. We can live on Earth, because the Sun makes heat and light for us.
