An easily recognized group of stars that appear to be located close together in the sky and that form a picture of imaginary lines connecting them. Constellations are usually named after an animal, a character from mythology, or a common object. (See Big Dipper, Ursa Major, and Ursa Minor.)

Student Reading Activity
Stars are huge balls of gas that give out large amounts of energy. The Sun is a star. The stars you see at night do not seem very bright compared with the Sun because they are much further away. These stars are around us all the time, We cannot see them during the day because light from them is very faint compared with the light from the Sun. A collection of stars grouped together is called a galaxy. We are part of a galaxy called the milky way. All the galaxies and the space between them is called the Universe. We measure the gap between galaxies in light years.
