Build A Solar System Orrery

It shows you the relative positions of the planets in the solar system during a given year and month.

Build a solar system orrery.

Orreries come in all shapes and. Once complete with the orrery move on to building the orbiter an accurate working model of the earth moon and sun system designed to predict solar and lunar eclipses and demonstrate the rotation and orbits of the earth and the moon. I have always wanted to build a working model of our solar system often called an orrery but was never able to find a design or set of plans that inspired me. And like a globe an orrery also serves a practical function.

Having never worked with gears i believed that designing my own was far beyond my skill level but that s never stopped me before. An orrery is a mechanical model of the movement and position of the planets in our solar system. An orrery is a mechanical model of the solar system that illustrates or predicts the relative positions and motions of the planets and moons usually according to the heliocentric model wikipedia in this instructable i will share how to make a fully 3d printed orrery of the sun with the planets from mercury to saturn. This project explores the use of plywood to make mechanical decorative and structural parts.
