LEGO Technic 42179 Planet Earth and Moon in Orbit

LEGO® Technic Sun, Earth and Moon Model (42179)

Experience the wonder of our solar system with the LEGO® Technic Planet Earth and Moon in Orbit (42179). This interactive model lets builders explore how the Earth orbits the Sun while the Moon simultaneously orbits the Earth — all driven by a gear system for realistic motion. 

Turn the crank to set the system in motion: as the gears turn, the Earth and Moon rotate in sync, allowing you to recreate their orbital paths and study the mechanics of their movement — just like in real life. The set also includes print details for the months and Moon phases, helping to visualize how the Moon changes over the course of a year. 

Designed for young space enthusiasts, this model isn’t just educational — it’s also meant to be displayed. With the LEGO® Builder App, you can zoom in on 3D views of the model, rotate it, and track your progress as you build.
