With a simple turn of a crank, you can watch the Earth and Moon gracefully orbit the Sun, allowing children to visualize and understand the mechanics of our solar system. The set includes a unique printed plate that features the months and phases of the moon, which helps to explain how Earth’s tilt and orbit create the changing seasons we experience. For a smooth and intuitive building process, the LEGO Builder app provides 3D instructions, allowing you to zoom in and rotate the model as you build. This non-toxic, meticulously designed set makes for an ideal gift for any child fascinated by planets, outer space, or engineering.
