An orrery is a mechanical model of the solar system, showing motions of our moon and the earth around the sun. The Orrery exhibit has chains and gears safely housed under transparent covers, yet it gives visitors an intimate walk-around view. Colorful graphics explain what makes summer and winter happen and what's happening during an eclipse of the sun or moon. Whether you come from the southern or northern hemisphere, you'll understand the seasons better with the Orrery exhibit.
