Ugears Mechanical Tellurion Model Kit

Turn the handle of the Ugears Mechanical Tellurion to set the Sun, Earth and Moon into motion and observe a simplified mechanical representation of key astronomical cycles. The model illustrates the heliocentric arrangement of the Solar System, day and night, phases of the Moon and seasonal changes. The position of the three bodies can also be adjusted manually to demonstrate different configurations and explain why lunar phases occur. By working directly with the model, users can explore the relationship between Earth's orbit, the Moon's orbit and basic calendar and timekeeping concepts. The detailed wooden mechanism is designed as both an educational tool and an engaging construction project for people interested in astronomy, mechanics and hands-on science.
