In most depictions of the Solar System, planets are drawn big enough to show details and placed side-by-side to show order. The scale of the planets and the space in between them are usually a footnote. Alex Gorosh and Wylie Overstreet were curious about what you would get if you placed scale in the foreground. So they built a 7-mile model of the Solar System to scale in the middle of the desert, with Earth the size of a marble.
