Pluto (IPA: /ËpluËtÉÊ/), designated (134340) Pluto in the Minor Planet Center catalogue, is the second-largest known dwarf planet in the solar system. It orbits between 29 and 49 AU from the Sun, and was the first Kuiper Belt Object to be discovered. Approximately one-fifth the mass of the Earth's Moon, Pluto is primarily composed of rock and ice. It has an eccentric orbit that is highly inclined with respect to the planets and takes it closer to the Sun than Neptune during a portion of its orbit. Pluto and its largest satellite, Charon, could be considered a binary system because they are closer in size than any of the other known planetoid/moon combinations in the solar system, and because the barycentre of their orbits does not lie within either body. However, the International Astronomical Union (IAU) has yet to formalize a definition for binary dwarf planets, so Charon is regarded as a moon of Pluto. Two smaller moons, Nix and Hydra, were discovered in 2005. Pluto is smaller than several of the natural satellites or moons in our solar system (see the list of solar system objects by radius).
From its discovery by Clyde Tombaugh in 1930, Pluto was considered the ninth planet from the Sun. In the late 20th and early 21st century, many similar objects were discovered in the outer solar system, most notably the Trans-Neptunian object Eris which is slightly larger than Pluto. In August 2006 the IAU redefined the term "planet", and classified Pluto, Ceres, and Eris as dwarf planets.[1] Pluto is also classified as the prototype of a family of trans-Neptunian objects.[2][3] After the reclassification, Pluto was added to the list of minor planets and given the number 134340.[4][5]

Well apparently it was demoted from planet to dwarf planet give it a good 5 years and we will be calling it LITTLE PEOPLE planet to be politcally correct until we can create a rocket and an artificial atmosphere we won't be able to send the little people back to their planet.

Pluto is the smallest planet in the solar system and is the furthest one away (that we have discovered anyway).
