The model extends along Route 1, between the University of Maine at Presque Isle campus and the Houlton Information Center at the end of I-95. The model has ten major components, those being the sun and the nine planets from Mercury to Pluto, with moons for Earth, Saturn, Jupiter (4) and Pluto. All planets except Pluto are visible from the road. Educational information on the planets can be found in the brochure, available at the Information Center in Houlton.
