You know, I completely forgot about this until dancinastrophys
reminded me today....
En route to Caribou last year, I noticed planets along the highway on the way up. They'd been painted and positioned, to scale, along a length of US Highway 1. It's the Maine Solar System Model
, the world's largest to-scale 3d solar system model
in the world
¹ -- 1:93,000,000 scale. A few moons (Luna, Io, Callisto and Charon among others) also make the cut. Pluto's since been retired, but it did get to hang out at the adults' table for a while.
The sun is 50 feet across, Earth 5.5 inches, Jupiter 61.4 inches -- Earth is one mile away from the sun, Pluto (pre-demotion, of course) was one inch across and 40 miles away from Sol.
¹Redundant much? Feh. But as we all know, Earth is the largest planet in the world
