Scaling Earth to a Marble
One of my toys is a blue marble with green continents painted on it. It not perfectly round, but a few random measurements with a 10-micrometer-repeatable dial caliper average to 21.85 millimeters diameter. What if we scaled the solar system, planets and distances, so that the Earth was the size of that marble?
Here's a text snapshot of a crude that I created:
