“Maine’s Solar System Model: A Cosmic Journey on Earth!”

September 4, 2025by Ranger Tom0
The Maine Solar System Model is a unique attraction that offers an out-of-this-world adventure for space enthusiasts. Spanning 40 miles along Route 1 from the University of Maine at Presque Isle to the Houlton Information Center, the model is the largest 3D printed solar system in the Western Hemisphere. The model is a scaled representation of the solar system, with each mile representing approximately 93 million miles in space.

The model was created by a group of volunteers, led by UMPI professors Kevin McCartney and David Hobbins. The project began in 1997 and was completed in 2003. It features all the planets of our solar system, including Pluto, which is still included despite its reclassification as a dwarf planet. Each planet is accurately depicted to scale, both in size and distance from the sun, providing a tangible perspective of the vastness of our solar system.

The Maine Solar System Model is not just a roadside attraction but also an educational tool. It’s used by schools and universities for teaching astronomy and space science. Visitors can take a self-guided tour along Route 1, starting from the sun located at UMPI and ending at the dwarf planet Eris, located 40 miles away at the Houlton Information Center. The model offers a unique, hands-on experience of our solar system and is a must-visit for anyone interested in astronomy.
