How Big Is the Solar System
... About 5 billion years ago our Solar System did not exist at all. Instead, there was in its place a large cloud of gas and dust called a nebula. Over many millions of years, the immense gravity of this large cloud caused the dust and gas to slowly fall inward towards its center. As matter in the clou ...

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.
