                                  GALAXIES

                  Galaxies are composed of billions of stars. (Stars

            are big celestial bodies such as the Sun. Neither the

            Earth nor the Moon is a star.) There are about three
            trillion stars in the biggest galaxy. In a galaxy of an

            average size, there are about 200 to 300 billion stars,

            while there are about 100 billion stars in a small

            galaxy.
