Tower Orrery (planetary solar system model) in Walnut, Stone and Brass by OrreryArt.

An orrery is a mechanical model of the solar system used to present the movements of the planets around the Sun.

“The Tower Orrery” shows the proper relative speeds of the nine planets and the compound relative orbital movement of Earth’s moon. The Sun, nine planets and twenty-two moons are made of beautiful semi-precious stone spheres. Also, you can have brass and hematite planets with stone moons for a “classical” orrery.
