Science + LEGO = Awesome

Jason Allemann of JK Brickworks (previously featured here) created this wonderful LEGO orrery that depicts the moon orbiting the Earth as both of them orbit the sun. It’s powered by Power Functions M-Motor or manually operated by turning a little crank on the side.

Due to limitations in the components available to him, Allemann’s orrery is about 97% accurate. The itty-bitty moon orbits the Earth every 28 days and it takes the LEGO Earth 375 days to complete its year-long orbit of the Sun.

“I tried to focus on making the rotation and movements as accurate as possible without making it too complex… The relative sizes and distances between the objects is obviously not to scale, a concession often taken with these models. It’s also missing the tilt of the Earth and inclination of the Moon’s orbit. Perhaps some things that could be added in the future.”
