Because there's jackshit on the internet today but a guy who bit a snake, here's a graphic depicting all our solar system's planets to scale (come on -- would it have killed you to still include Pluto?). As tipster Chris pointed out, all the terrestrial planets could fit comfortably inside Uranus. Inmyanus? The rest of them too. :/
Thanks to Chris, who heard there are people out there that can fit entire galaxies up there.
