walk-in Tellurion

This walk-in tellurion represents the Earth orbiting the Sun, with the Moon orbiting the Earth, moving in real-time. With a control panel one can set any given date and will then be presented with the constellation of Sun, Earth and Moon on that day. A tellurion is a clock, surmounted by a mechanism that depicts how day, night and the seasons are caused by the movement of the Earth on its axis and its orbit around the Sun. It is related to the orrery, which illustrates the relative positions and motions of the planets and moons in the solar system in a heliocentric model.
