STEM UGears Mechanical Tellurion

The idea of a space-themed model has been "floating in the ether" at Ugears for some time now. Every time we announce a new model, hopeful Ugears fans will ask, "Is it an orrery?" From this shared desire a project was born. Our mission: to spread knowledge of space and time by helping people visualize the movements of the planet we live on, and its closest satellite, the moon.

UGears is proud to present the Mechanical Tellurion, an accurate wooden model representation of our corner of the universe. A tellurion (also spelled tellurian, tellurium, and sometimes called a loxocosm), is an ingenious mechanism that depicts the cosmic dance between Sun, Earth, and Moon. The causes of day and night, the phases of the moon, and the changing seasons are seen and understood according to the movements of this 3D puzzle.
