From a medieval astronomical clock to a golden, modern orrery, its always easier to have visual aids when learning complex concepts, like how the universe works! Though early scientists believed the Earth was at the center of our solar system, by 1514 the astronomer Copernicus placed the Sun at its center. The first modern mechanical model of the solar system was made in the early 1700s and named after its patron, the Earl of Orrery. Makes a perfect puzzle for any space or astronomy fan!
