This is the LEGO® Technic Planet Earth and Moon in Orbit (42179), a 526-piece interactive model that demonstrates the orbital relationship between the Earth, Moon, and Sun.

Get ready to build a piece of the cosmos! This isn't just a model; it's a working mechanical marvel—a beautiful, hand-cranked orrery that brings the dance of our solar system right to your desk. Watch in amazement as you turn the crank and see the complex mechanics you've built set the heavens in motion. It's an incredible, hands-on journey through space and time!

A Cosmic Clockwork Masterpiece

The real magic of this set is the intricate system that drives the orbital paths. It's a fantastic showcase of engineering principles, all brought to life with LEGO® Technic.

• Turn the Crank: A simple turn of the handle engages a complex system of Technic gears that you assemble yourself, creating the realistic orbital paths.
• Learn As You Build: This set is a fantastic educational tool, demonstrating concepts like gravity, seasons, and moon phases with every rotation. The printed months and moon phase details are a brilliant touch.
• Precision Engineering: The entire mechanism is built from a variety of clever Technic pieces, from sturdy beams to essential pins and connectors.
