This project teaches students how professional astronomers map out the objects in our solar system. Students learn the relationship between 2D and 3D maps and between terrestrial coordinate systems and celestial coordinate systems. Using SDSS data, they create a map of the asteroids in our solar system as seen from earth and measure the angle of the ecliptic. This gives them the tools and understanding to work out the cause of the seasons for themselves.
