Anchorage Light Speed Planet Walk

Friday, Jul 31 2015 by kjfitz
The Anchorage Light Speed Planet Walk is a scale model of our solar system. Taking the walk, you experience the relative size of the planets and their distance from the Sun. The scale was chosen so that a leisurely walking pace mimics the speed of light. On this scale, each step equals the distance light travels in one second (300,000 kilometers or 186,000 miles).

It would take you about 8 minutes to walk from the Sun station to the Earth station, just as it takes 8 minutes for a light beam to travel from the real Sun to the real Earth. Similarly, it would take you and a light beam 5 1/2 hours to reach Pluto at Kincaid Park.
