#BAFact: To scale, if the Earth/Sun distance were one inch, a light year would be exactly one mile.

A little bit of fun math for you: if you made a scale model of the solar system where the distance from the Sun to the Earth were one inch, then a light year in the model would be almost precisely a mile in the real world. How cool is that?

I do the math here: http://blogs.discovermagazine.com/badastronomy/2012/06/18/bafact-math-give-him-an-inch-and-hell-take-a-light-year/﻿
