The solar system walk was designed by a high school student astronomy buff, and was the Centennial Project of the Anchorage Rotar Club.
The model's scale was "chosen so that a leisurely walking pace mimics the speed of light." The Earth is at 5th Ave. and K St., an 8 minute walk (how long the light of the Sun takes to reach Earth). Pluto is in Kincaid Park, SW of Anchorage, a 5 1/2 hour walk by way of the other planets.
