This site is intended for students in grades K through 8. StarChild is a learning center for young astronomers ages 5-13 to learn about the solar system, the Milky Way galaxy, and the universe beyond.
Constellations can be a useful way to help identify positions of stars in the sky. Constellations have imaginary boundaries formed by "connecting the dots" and all the stars within those boundaries are labeled with the name of that constellation.
Explain that many star groups were named for the people, animals, and objects our ancestors imagined seeing when they looked at the stars. Encourage students to share any information they possess about constellations. Display a constellation chart or pictures of starry skies as you read (or have students read) the attached constellation myths.
What is the solar system? It is our Sun and everything that travels around it. Our solar system is elliptical in shape.

They just seem to come from that part of the sky because of the way the Earth encounters the particles moving in the path of the comet's orbit.
