Explore the Solar System with LEGO Technic

Curious minds can build a dynamic Earth–Moon system in orbit around a simplified Sun with LEGO Technic Planet Earth and Moon in Orbit (42179). This 526‑piece set invites hands‑on construction and prompts tactile exploration of orbital motion, rotation, and scale. The rotating crankshaft lets kids feel how turning mechanisms can drive movement, making abstract ideas more tangible through play.

What you’ll see and learn

The model features printed months and moon phases to illustrate how the Earth’s yearly journey relates to seasonal changes. While not a substitute for a textbook, the visual cues help connect concepts to real-world cycles in a friendly, age‑appropriate way.

• Interactive learning: turn the crank to observe orbital motion and rotational effects.
• Visual cycles: printed months and moon phases offer a concrete way to track changes over the year.
• Engineering in play: true-to-life Technic details spark curiosity about mechanisms and design.
