LEGO builder marian519 built this mechanical contraption inspired by a vintage mechanical clockwork. As its crank is turned, it demonstrates the rotational relationships between the Earth, Sun, and Moon. The instructions and parts list for the 2305-piece, 70-gear model are available for purchase on Rebrickable.
Awesome Solar System
ChenYi makes these stitched-edge cloth desk mats with colorful illustrations of our solar system. Measuring 35.4″ w x 15.7″ d, they’re big enough for a full-size keyboard, a mouse, and other desk accessories. Choose from six variants, including Celestia, Galaxy, Nebula, Orbit, Revolution, and a white Solar System.
Take out your stress on the entire Solar System with these squishy spheres. The set includes nine full-color planets and a larger Sun for them to orbit around. They’re definitely not to scale, but a squeezy Sun that’s 1.3 million times bigger than Earth isn’t exactly a practical toy to wrap your hand around.
