Scaling and the Solar System
... 1 inch = 100 miles (or 1 cm = 50 kilometers for a typical metric map). In the metric case, the scale factor for the entire map would be: SF = 1 cm/50 km = 1 cm/5,000,000 cm = 2 × 10 -7. Try this on your calculator and see if you get the same answer. To carry the analogy a bit further, imagine that t ...

Orrery
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; but since accurate scaling is often not practical due to the actual large ratio differences, a subdued approximation may be used instead. Though the Greeks had working planetaria, the first orrery that was a planetarium of the modern era was produced in 1704, and one was presented to Charles Boyle, 4th Earl of Orrery — whence came the name. They are typically driven by a clockwork mechanism with a globe representing the Sun at the centre, and with a planet at the end of each of the arms.
