An illuminated three dimension model of the Sun and planets teaches planet identification, sizes, distances and colors. The planets may be set by month to show their relative positions. A sturdy base supports the 6-in. diameter Sun with the outer planet 18 inches from the Sun. Illustrated study guide includes planet position tables. All plastic, with electric fitting to illuminate the Sun.
