Whipple Museum Giant Orrery

__SPACER__ This grand orrery displays the Sun in the centre, and the 6 planets known at the time with their moons. Uranus, Neptune and Pluto had not yet been discovered when this orrery was made. Because it is calibrated for the Julian calendar, G which was abandoned in favour of the Gregorian calendar G system in 1752, the assumption is that it was manufactured before that date.

It was made by the renowned instrument maker George Adams, XR who supplied instruments to King George III.
