This ringed sculpture landed on Earth more than two decades ago, one small part of a sprawling educational display dreamed up by a geology professor and brought into existence by some 700 volunteers. Today, the display consists of 20 celestial objects fixed in their orbits along about 95 miles of road, all sized and spaced to scale. Cruise past the succession of planets and moons at seven miles per hour, and you’ll be traveling, in relative terms, at the speed of light, although drivers behind you might disagree. The most recent upgrade, an openwork metal sun, debuted the same day a total solar eclipse passed over Maine last spring, when the real sun hid behind the moon.
