It does, probably is. Despite its small size relative to the rest of the planets, and its somewhat lower density than the other four rocky planets (Mercury, Venus, Earth, Mars), Pluto’s out by itself and better able to capture new satellites. The view that Pluto-Charon was formed in an impact event is the more popular explanation for Charon’s origin.
Someone please bring me up to date: Is Pluto still considered a planet? I learned that as a child, so I’m inclined to stick with that.
