Assemble this complex machine using snap-together plastic parts to learn how the gears and wind-up mechanism work to spin the model. Detail each planet with colorful, realistic-looking printed planet graphics. Learn about the order of the planets, their relative sizes, their rates of revolution around the sun, their appearance, and other planetary facts. This kit includes full-color step-by-step illustrated assembly instructions.
