The Tellurion is a practical and educational astronomical model that illustrates the orbit of the Earth and the Moon around the Sun, helping to visually explain various natural phenomena.

The device is designed to support learning, making it possible to demonstrate the changing of seasons, variations in day and night length, solar and lunar eclipses, and lunar phases in an academic or home environment.

At the center of the model is a red sphere representing the Sun, featuring an integrated light source. This illuminates the Earth and Moon models just as it occurs in space, accurately mimicking sunlight. A mechanical gear system ensures the simultaneous movement of the elements, making the fundamental principles of astronomy simple and engaging for students to understand.
