This video, made by Wylie Overstreet and Alex Gorosh, is apparently the first attempt to make a model of the solar system completely to scale: that is, the sizes of both the planets and their orbits must be on the same scale of measurement. The one constraint is that they start with a model Earth the size of a marble: the rest follows automatically.
The model was constructed in the Nevada desert, and they needed seven miles of empty space to do it—and even that is excluding Pluto (it’s a planet, dammit!), an inclusion that would have made the model much larger (readers can calculate how much larger). It’s a laborious and fascinating task, and has garnered nearly 900,000 views in the last three days.
The final test, in which they compare the image of the real rising Sun with that of the model Sun, both from the vantage point of the model Earth, is lovely. Kudos to the filmmakers!
