Orrery Model Rotating Brass Gears 9 Planets

✔ Observe planetary motion: Watch the Moon trace its path around Earth as Earth travels around the Sun. The nine-planet display, including Pluto, and 28 moons make celestial movement easier to observe.

✔ See the mechanism at work: An exposed mechanism reveals solid brass gears beneath the rotating planets. The display demonstrates how the model represents different orbital speeds, from Mercury’s roughly 4-second orbit to Pluto’s roughly 4-hour orbit.

✔ Detailed materials and construction: Stone spheres, a twelve-sided oak barrel, brass feet, and an engraved calendar and zodiac ring give the model its distinctive construction. A detachable brass armillary half-sphere crowns the top.
