Nearly everyone spent at least some amount of time as a student cobbling together some sort of dubious model of our solar system for science class. But in rural Maine, residents have taken such projects to a whole new level. “A community endeavor four years in the making before its completion in June, the Maine Solar System Model is a three-dimensional roadside scale model of the solar system, stretching from the Northern Maine Museum of Science in Presque Isle 40 miles southward to the hamlet of Houlton. The scale is 93 million to 1.” The sun is represented by a huge mural at the museum, whereas Pluto is a 1-inch diameter ball, in accordance with proper scaling.
