The solar system starts in Northern Maine? In Aroostook County? What? When driving along US Rt 1 in Northern Maine, you'll see some big planets..some little ones, but all to scale and in the right location to simulate the ones James T Kirk explored aboard the Starship Enterprise.  Check out the details here!  See what the Smithsonian Magazine says about the whole affair here.  The large planets of the 9 are easy to spot at 55 miles per hour but the little guys take a little more scrutiny and detective work.  Hey..what about Pluto...you're not messing with the little cold planet way way out there are you?

          Stretched over a whopping 40 miles, the solar system in Maine will keep you from falling asleep at the wheel and is way way more fun than counting cows or searching for one working light VW's to amuse the kids. See the basic layout here!   The speed of sound at 7 miles per hour? Yes! In  Maine  solar system.
