LEGO Technic set 42179-1 Planet Earth and Moon in Orbit models the relationship between the Sun, Earth and Moon as a working display. A hand crank drives the exposed gear train, moving Earth around the Sun while the Moon circles Earth. Printed month labels show the planet's position through the year, and a separate scale indicates the Moon's changing phases. The blue Earth, grey Moon and yellow Sun sit on angled Technic beams that keep each orbit easy to follow. Turning the handle reveals how several gears coordinate the two rotations without hiding the mechanical function inside a closed base.
