All (known) Bodies in the Solar System Larger than 200 Miles in Diameter

Kokogiak has created an utterly splendid image of the 88 known bodies in the solar system larger than 200 miles in diameter, arranged in order of size against a rich black background. There were a lot of design choices to make, Kokogiak explains:

I chose the Earth as the visual axis, placing it full-disc at 1000 pixels. The larger planets and Sun just bleed off the page, but still give a sense of scale by the visible curve of their limbs. And where to cut it off on the small end? Why 200 miles? Well, that's entirely arbitrary. It so happens that I have a fondness for Saturn's moon Mimas (247 miles across), and 200 was the next round number down. That simple. Also, it captures a fair percentage of known Trans-Neptunian Objects (51), enough to give a good idea of their place in the larger scheme of things.

The full-screen version:
