Solar System Planets in Orbit

A hand-cranked gear mechanism drives all 8 planets simultaneously. Each planet moves at a different speed around the central Sun, replicating the relative orbital motion of the solar system. The model functions as both a working mechanical display and an astronomy learning tool.

572 pieces build the complete model, suitable for ages 10 and up. Each planet includes an individual information panel covering key facts about that body. The planets can be manually realigned by hand to reset the model before operating the crank again.

The set measures 27 cm high and 26 cm wide when all planets are aligned, and 38 cm wide when the outermost planets are at maximum spread.
