The model includes representations of the planets Mercury, Venus, Earth and the Moon, Mars, Jupiter, and Saturn orbiting a clear orb representing the Sun thanks to a series of gears. The particulars of the project, which took Condal 10 months to complete, are broken down in meticulous detail in a series of blogs over on Condal’s website.
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.
