It was built by Benjamin Cole of London between 1748 and 1760. The four inner most planets are mounted on plates and connected to a mechanism which allows them to rotate about the sun at their correct rates. Jupiter and Saturn are attached to arms extending outside the main structure which allow them to rotate freely. The base of the orrery has 12 windows instead of wooden panes so that the interior mechanism to be viewed. Twelve beams support a ring which encircles the inner planets and is engraved with the signs of the Zodiac and the Julian and Gregorian calendars.
