## What is ARrery?

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. 

An ARrery is the equivelant of an orrery but is an augmented reality model of the solar system. With the Augmented Reality Orrery it is possible to turn off planets, speed up and slow down the simulation.  The orrery also has the ability to turn on and off a milky way backdrop.
