Lego Orrery Sun Earth And The Moon Lego Mindstorms Robot Inventor Each rotation of the crank represents one day, and the earth rotates once with every turn. the moon orbits the earth every 28 days, the sun makes a full rotation every 25 days, and the earth orbits the sun every 375 days. some notes on the construction. for the large turntable, i’m using the newest 60 tooth version. They will be taking home $100 worth of lego 🙂 earth, moon and sun orrery. by jkbrickworks. moc 4477 • 462 parts • technic. see our review of this moc. the building instructions for this moc can be found on an external site: view building instructions.

Lego Ideas Orrery Sun Earth And Moon This is a lego orrery built primarily out of technic, with a studs out model of the earth. it is motorized and includes kinematics for: earth rotating on its axis. sun rotating on its axis (every 36 earth days) moon rotating around the earth (every 25 earth days) earth rotating around the sun (every 327 earth days) earth's tilted axis (22.5º. The gear ratios are as follows (counting one model earth rotation as one 'day'): moon completes one rotation around the earth: 28 days (a synodic month*) earth completes one rotation around the sun: 360 days (a year) the sun rotates fully on its axis: 24 days ** * a synodic month should be about 29 days and a sidereel month should be about 27 days. An orrery is a mechanical model of the solar system that replicates the planets movements around the sun. here jk brickworks narrowed the focus to just the sun, earth, and moon. it surprises me that lego haven't released an orrery, seems like it would fit really well into their ethos of play and learn. it would also be great to get technic sets. I made a lego orrery, a solar system model but with just the sun, earth and the moon. if you like this video, leave like and subscribe to not miss my new vid.

The sun earth moon orrery accurately simulates the rotation and orbital motion of the sun and the earth moon system. the precession of the nodes of the lunar orbit. two cranks for easy operation. one full clockwise rotation of the crank advances the orrery by one day. i also offer a design for an orrery with a simpler stand and 30% less parts. When i first saw some of the spring 2024 releases, #42179 planet earth and moon in orbit immeditately caught my imagination! i absolutely love the idea of playing with an orrery to see how the earth rotates around the sun, but have never had the chance to play with one. the idea of building one using lego technic pieces is very compelling.
