Pluto has also been a subject of speculation involving future efforts by humanity to colonize that body, efforts often complicated by the presence of extraterrestrial "campers" or even of pathogens, usually [[virus]]es, native to Pluto.

[[Image:PlutoSystem.jpg|150 px|left]]Pluto has at least three [[moon]]s, the largest of which is [[Charon]]. (The size of Charon relative to Pluto is such that Pluto and Charon are often collectively considered to be a binary system. Due to their sizes, the center of rotation is not "inside" pluto, but rather above its surface. Rather than rotating around Pluto, Pluto and Charon rotate around a common center of gravity.) The others are named [[Hydra (moon)|Hydra]] and [[Nix]].
