The Orbiting Solar System kit allows you to create a mechanical model of the solar system. Wind it up and watch the planets revolve around the sun. Made for Thames and Kosmos, assemble this complex machine, also known as an orrery, using snap-together plastic parts to learn how the gears and wind-up mechanism work to spin the model.
