Orrery. A small orrery showing Earth and the inner planets. An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often ...
Solar System model. Solar System models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the Solar System have been built for centuries. While they often showed relative sizes, these models were usually not built to scale. The enormous ratio of interplanetary ...
He inherited the estate in 1714. An orrery, a model of the Solar System named after the 4th Earl of Orrery. Boyle became a Fellow of the Royal Society in 1706. In 1713, under the patronage of Boyle, clockmaker George Graham created the first mechanical Solar System model that could demonstrate proportional motion of the planets around the Sun.

The Antikythera mechanism (/ ˌæntɪkɪˈθɪərə / AN-tik-ih-THEER-ə, US also / ˌæntaɪkɪˈ -/ AN-ty-kih-) [1][2] is an Ancient Greek hand-powered orrery (model of the Solar System). It is the oldest known example of an analogue computer [3][4][5] used to predict astronomical positions and eclipses decades in advance. [6][7][8] It could ...
The orrery The mechanical works in the space above the ceiling that keep the mechanism in operation Animation by 3D illustrator Paul Becx with an accelerated rendering of the Eisinga planetarium dials. An orrery is a planetarium, a working model of the Solar System. The orrery is painted with royal blue glimmer and outlined in shiny gold paint.
