First is a straightforward lineup of objects in our astronomical neighborhood, from the Sun down to the 203-mile asteroid Davida (click at right to view the full image). I've seen graphics like this before, but can't recall seeing one that included so many moons and other small bodies. The zone from Callisto through Ceres was oddly surprising to me.

Second, a cool little video that sends you spinning in the opposite direction, from the smallest planets to the most massive stars. The first half left me thinking, again, "Seen it before," but once you pass the Sun, the leaps in size become truly mind-boggling.
