Northern Maine’s Aroostook County has a 40-mile-long scale model of the Solar System along U.S. Route 1, with one mile representing the distance from the Earth to the Sun, or one astronomical unit. The Sun is at the Northern Maine Museum of Science in Folsom Hall on the campus of the University of Maine at Presque Isle, and Pluto is at the Houlton Information Center just north of the Interstate 95 interchange. Along Route 1, the remaining planets are placed at locations as three-dimensional models: Mercury, Venus, the Earth and Moon, Mars, Jupiter with four moons, Saturn with Titan, Uranus, Neptune, and Pluto. Developed as a community project in 2000-2003 for public enjoyment and learning about the Solar System, it is the world’s largest scale model of the Solar System.
