Ever since the fourth grade when we made solar systems with coat hangers and styrofoam balls, I’ve wanted to build a more realistic Orrery but was never able to find a design or set of plans that inspired me. Having never worked with gears, I believed that designing my own was far beyond my skill level, but that’s never stopped me before. After three months of study and design followed by seven months of machining, I came up with the following Orrery.
