A 1766 Benjamin Martin mechanical model, or orrery, on display at the Harvard Collection of Historical Scientific Instruments. 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.
The construction system Meccano is a popular tool for constructing highly accurate orreries. Model 391, the first Meccano Orrery, was described in the June 1918 Meccano Manual. [29] [30] In Dune Messiah, the 1969 sequel to Dune, there is a description of a desktop orrery representing the two moons of the fictional planet Arrakis and its sun.
The Sagan Planet Walk has inspired the creation of other scale-model Solar Systems in the United States. The Delmar Loop Planet Walk in St. Louis, Missouri: "In 2006, I became aware of the Sagan Planet Walk in Ithaca, NY, and as an amateur astronomy buff, I found the idea of a scale model solar system to be a fascinating concept.
The Antikythera mechanism (/ ËŒ æ n t ɪ k ɪ ˈ θ ɪər É™ / AN-tik-ih-THEER-É™, US also / ËŒ æ n t aɪ k ɪ ˈ-/ 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] It could be used to predict astronomical positions and eclipses decades ...
New models of the Solar System are usually built on previous models, thus, the early models are kept track of by intellectuals in astronomy, an extended progress from trying to perfect the geocentric model eventually using the heliocentric model of the Solar System. The use of the Solar System model began as a resource to signify particular ...

An original Mendocino Motor is a light commutated motor. Two opposite solar panels are connected plus to opposite minus and minus to opposite plus. A coil is switched between these bridges. The solar panel in the sun/light produces more electricity than the solar panel in the shadow. So the solar panel in the sun dominates the flow of electricity.
The walk begins here: the Sun model at Higher Maunsel Lock. The Somerset Space Walk is a sculpture trail model of the Solar System, located in Somerset, England.The model uses the towpath of the 22-kilometre (14-mile) Bridgwater and Taunton Canal to display a model of the Sun and its planets in their proportionally correct sizes and distances apart.
