Over at Kokogiak, Alan Taylor has published a very impressive mosaic image. It shows all known bodies in the Solar System whose diameter is larger than 320 km (500 miles).

He writes:

It’s just one of those things I’ve been itching to make for a long while, frankly because I wanted to see it - a visual listing of objects in the Solar System, ordered by size.
[...]
The larger planets and Sun just bleed off the page, but still give a sense of scale by the visible curve of their limbs.

Alan has published two versions: One in metric measurements; the other in imperial:
