The "Earth-Moon" mechanical system

The “Earth-Moon” mechanical system represents one revolution of the Earth in about 24 hours, and one revolution of the Moon around the Earth in 27 days, 7 hours, 43 minutes, and 11 seconds, or about 27.32 days.

Behrens developed the “Earth-Moon” system to show the orbits of the stars according to the laws of the universe. 

The orbit of the Moon on the dial completes one revolution in 28 days, while the Earth in the middle rotates in 24 hours.
