How to make sun, earth and moon system DIY orrery

[@alekumar]

Amazing, Wish every school had one of these. With proper lights and shadow, phases of moon and eclipses could be demonstrated so vividly. If it were elliptical, it could also show weathers, and earth's tilt would explain other variables.

Hi, greta idea, BUT the moon is rotating the wrong way. DON'T PANIC, you just have to reverse/return the cord at onr polley and you're done 😉

[@richoddinott8778]

Good job. But the moon should orbit the earth anticlockwise as the earth orbits the sun. If you put a twist into your string so it makes a figure of eight, it will then go the correct way. 🙂

Thank you

[@mosheklang]

To make it even more correct, the moon should circle earth 12 times for each time that earths circles, the sun…
