This LEGO Technic Planet Earth and Moon in Orbit building set invites young space enthusiasts aged 10 and up to construct a dynamic model of our solar system. As kids assemble the 526-piece set, they'll create a working orbital display where turning the crank demonstrates how the Earth and Moon revolve around the Sun. The model features printed educational details including moon phases and months, helping children visualize how Earth's orbit creates seasonal changes. When completed, the display measures over 9 inches high, 12.5 inches long, and 7 inches wide, making it both an engaging educational tool and attractive space-themed decor. The included LEGO Builder app enhances the experience with intuitive 3D building instructions, allowing builders to zoom, rotate, and track their progress. Perfect for young astronomers, this set makes an excellent birthday gift that combines hands-on building with fascinating astronomical concepts.
