With 865 pieces, it forms a hand-cranked gear model in which Earth and Moon move around the Sun at the correct relative speeds.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe inspiration – the orrery\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eAn orrery is a mechanical model of the solar system that depicts the relative positions and movements of planets and moons, usually in the heliocentric model. Since true scale accuracy is barely achievable, such models generally work with simplified sizes and distances. The name goes back to a device built around 1712 by John Rowley, named after his patron Charles Boyle, the 4th Earl of Orrery.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe model – CaDA C71004W\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eTurn the crank clockwise and a gear mechanism sets Sun, Earth, and Moon in motion: according to the manufacturer, one crank turn corresponds to roughly one rotation of the Earth, i.e. one day, 30 turns to roughly one orbit of the Moon, and 365 turns to one orbit of the Earth around the Sun. A month ring with twelve month markers shows the progress through the year. A yellow Sun, blue-green-white Earth, and light-grey Moon sit on a black gear frame with a brown base and gold-coloured month ring. The instructions also include interesting facts about the solar system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical data\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe CaDA C71004W comprises 865 pieces.
