Pluto is a dwarf planet in a system beyond Neptune called the Kuiper Belt. NASA says, "...and probably has a rocky core surrounded by a mantle of water ice." It is also stated that methane and nitrogen frost coat Pluto's surface. Pluto's orbit around the sun can take **__248__** **__//years//__**. Well, that would be unlucky to wait so long for your birthday! Pluto's largest moon, Charon, is about half of Plto's size. The difference between the two is 12,200 miles (or 19,640 kilometers for those who aren't American). Charon's orbit around Pluto is 6.4 Earth days, and one day in Pluto is the same--6.4 Earth days. Charon doesn't rise or set, it hovers on the same spot, with the same side always facing Pluto.

Some astronomers believe that Pluto and it's moon Charon has cryvolcanoes (like volcanoes, but they spew ice out instead!).
