Our universe is a big place with all kinds of interesting things in it. There are nine planets in our universe. Earth is the planet that we live on. The sun, which we see every day, is not a planet. It is a star. There are also many other stars that we see in the sky at night. Asteroids and meteors are also in space, but they are not planets either. Comets exist in our universe, too. Sometimes you can see them travel past the earth. They have bright tails you can see as they travel by our planet.
