CaDA C71009W is the updated version of the CaDA C71004W Solar System model, designed to demonstrate the fascinating movements of the Sun, Earth, and Moon through precise mechanical engineering. Using a synchronized gear system, the Earth rotates on its axis while orbiting the Sun, and the Moon revolves around the Earth while rotating at the same rate, accurately simulating why the same side of the Moon always faces the Earth. Turning the crank at the base drives the entire planetary motion system, creating an engaging and educational hands-on experience.
This model combines mechanical precision with learning and demonstration features, including manual operation with optional motorization. A carefully designed 1:375 gear ratio recreates day-night cycles, seasonal changes, and the visible rotational movement of the Sun for easier observation. CaDA C71009W offers a unique way to explore astronomy, physics, and gear mechanics through interactive building and operation.
