Description
This unsigned instrument closely resembles the orrery that Edward S. Ritchie offered in 1860. It is a simple crank-operated model showing the relative positions of the Sun, Mercury, Venus, Earth and Moon, Mars and its two moons, Jupiter (missing) and its moons, Saturn with rings and several moons, and Uranus. The stand is wood. The arms holding the planets are brass.
