Pluto is the farthest known planet in the solar system. Nearly six billion kilometers from the Sun, Pluto is a very small and lonely world. It is not a gas planet like its four closest neighbors, and is smaller than Earth's own moon! Many scientists question whether or not Pluto is even a planet at all. Some think that Pluto and it's moon Charon are instead moons from other planets that went astray. Pluto, made of ice and frozen gases resembles a moon of the gas giants more than some of the gas giants' own moons! Perhaps Pluto is a moon of Neptune sent into a new orbit by a yet unknown, distant tenth planet? There is no hard evidence to support this theory, but only science and time will tell.
