Activity 4 Read the text and answer the questions.
Pluto is a special planet. It travels around the Sun. It takes Pluto about 248
Earth Years to go around the Sun. Clyde Tombaugh discovered Plutoin 1930.
Pluto is about 40 times farther from the Sun than Earth. It has five small satellites (moons). To have a better look at the planet and its satellites, scientists sent a spaceship to fly close to it. The spaceship took many pictures. Scientists put the pictures together and learned more about Pluto. There is no air on the planet. It is so cold on the planet that air would freeze into something like snow. Without air, human beings can't live on the planet.
