Pluto, the god of the underworld. The ninth planet out from the sun is a rogue, and considered by some to not even be a planet. Pluto's orbit is eccentric, tilted about 17 from the Planetary Disk (the plane on which all other planets orbit the sun); and elliptical, its solar distance varying by almost 50% - Pluto is closer to the Sun than Neptune fir about 20% of its year.

Pluto has one moon, Charon, locked in a mutually geosynchronous orbit - that is, they always show the same face to each other, just like how we only ever see one side of our own moon (this is most likely a magnetic attraction). As, from our moon, the Earth is always in the same part of the Lunar sky; such is the view from these worlds, of their nearest neighbor. From Pluto, the Sun at high noon is only as bright as it is on Earth at about a half hour after sunset - still the brightest star in its sky, but there are many close contenders, like a stray comet.
