EDIT 2010-07-15: Go here for a version including Lutetia.
EDIT 2008-09-06: After the successful Steins flyby, the image has been updated.
After posting the montage of asteroids and comets to scale last week I got a lot of requests for a single-image version of the montage. Your wish is my command! Here is a single image of all of the asteroids and comets that have been visited by spacecraft, sized to be dropped in to a Powerpoint presentation, or even used as a desktop image, at 1600 by 1200 pixels. In the caption I've provided links to a much larger version of the image, a whopping 6000 by 4500 pixels -- that's handily large enough to print as a 16 by 20 inch (40 by 50 cm) poster or even larger. Of course, I'm just going to have to update this in two weeks once Rosetta has returned photos of Steins! Steins, by the way, is supposed to be about 5 kilometers in diameter, roughly the size of Annefrank or Wild 2, so I shouldn't have any trouble fitting it in. But once Rosetta visits Lutetia in July 2010, I'll have to redo the layout -- Lutetia is expected to be about double the diameter of Mathilde. Thanks very much to Joel Parker for correcting some of my numbers on the body diameters.
