Nice let's mine them for precious metals.
That’s No Moon: A Visual Asteroid Size Comparison

Because who can ever get enough visual asteroid size comparison videos, this is another from MetaBallStudio featuring a bunch of different sized asteroids, some real, some fictional, but all pale in comparison to the size of Uranus. Literally — the largest asteroid in the video is the fictional Texas-sized one from Armageddon, Uranus has a diameter of 31,518 miles. Your anus, much larger obviously.

Keep going for the video, as well as part one in case you missed it.
