The LEGO® Technic 42254 building toy lets children aged 10 and over build a home solar system featuring 8 planets orbiting the Sun. It supports STEM learning, turning education into a fun journey through space.
LEGO® Technic 42254 Orbiting planets of the solar system
Children set this solar system model in motion using a gear mechanism and a hand crank. They can then watch the planets orbit the Sun at their own speeds. To reset the mechanism to its starting position, simply align the planets by hand. The set also includes individual panels with detailed information about each planet, making the model serve as both an educational tool for space exploration and a dynamic decoration.
The building toy introduces children to astronomy and physics in a fun way, and the LEGO Builder app helps them with the construction.
