orrery

a mechanical model of the solar system in which the planets can be moved at the correct relative velocities around the sun

orrery

(o -rĕ-ree, or -ĕ-) An instrument or model that demonstrates the movements of some or all of the planets around the Sun, in their correct relative periods, by means of a set of small spheres mounted on wire rods and driven by an elaborate, usually clock-driven system of gears. The movements of satellites, such as the Moon, may be incorporated in the mechanism. The instrument takes its name from Charles Boyle, the 4th Earl of Orrery, who paid for such a device built in 1712; orreries were previously called planetaria.
