Motorized Orrery - Rear

A functional orrery depicting a fictional planet orbited by three moons.

 

The dial on the front shows (6) days of the week.

The gearing of the mechanism works out such that every full rotation of that dial:

 

The innermost (gold) moon makes 1/6th of a rotation

The middle (silver) moon makes 1/10th of a rotation

The outermost (sand green) moon makes 1/14th of a rotation.

 

The mechanism is also motorized.

 

Moving around to the back, after about 18 rotations gold and green line up again, and this time silver is almost perfectly opposite them.

Under the platform you can also see the switch that turns on the motor.
