When I was in high school, one of my science teachers took the class out to the football field and helped us create a model of the solar system scaled down to one hundred yards. That's a lot like what artist Mishka Henner did, except that he used a twelve-volume book of five hundred six pages each. The width of each page represents one million kilometers. Earth is on p. 155 of the first volume, and Jupiter on p. 283 of the second. Each celestial body is to scale, as well, with the Sun filling two pages and Mercury just a speck.
