... θ = arctan(dCJ /dJE ) where dCJ is the distance from Callisto to Jupiter and dJE is the distance from Jupiter to Earth. We just calculated dCJ = 0.012 AU, and part (i) yields the range of possible dJE , between 4.2 and 6.2 AU. The angle will be greatest when dJE is smallest, so: θ = arctan(0.012/4.2 ...

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.
