Traditionally, an orrery is a mechanical model of the Solar System, or at least the major planets. This device is driven by a clockwork mechanism that simulates the motion of the planets (and, in
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 not practical due to the actual large ratio differences, a
An Orrery is a moving, mechanical model of the Solar System. It shows how all of the planets orbit around the Sun . We have created an online version here, called the Electric Orrery .
An orrery is a mechanical model of the Solar System that shows the relative positions and motions of the planets and moons according to the heliocentric (Sun-centred) model.
Ein Orrery (Neutrum, [ˈʔɔɹəɹi]) oder eine Planetenmaschine ist ein mechanisches Gerät, das den Umlauf der Planeten um die Sonne veranschaulicht.
The orrery was a centerpiece of eighteenth-century London coffeehouse lectures. Lecturers would use it to demonstrate the motions of planets around the sun, and moons around the planets, explaining phenomena ranging from comets, eclipses and the phases of the moon to the seasons and day and night.
Dated 1712--3, this planetary model was made by the London instrument maker, John Rowley. Called an orrery or more correctly a tellurium, it is a demonstration device to show the motions of the

NASA''s Solar System Interactive (also known as the Orrery) is a live look at the solar system, its planets, moons, comets, and asteroids, as well as the real-time locations of dozens of NASA missions.
Orrery, mechanical model of the solar system used to demonstrate the motions of the planets about the Sun, probably invented by George Graham (d. 1751) under the patronage of Charles Boyle, 4th Earl of Orrery. In use for several centuries, the device was formerly called a planetarium.
