Pluto  (plt)

The ninth and usually farthest planet from the Sun as well as the smallest in size, with a diameter about one-sixth that of Earth. Pluto was not discovered until 1930, when Clyde Tombaugh noticed it while searching for an unknown planet thought to influence Uranus's orbit. Pluto's surface is covered with frozen methane and other ices, and its extremely thin atmosphere consists primarily of methane and nitrogen. Between 1979 and 1999 Pluto crossed inside Neptune's orbit and became, temporarily, the eighth planet in distance from the Sun. Because of its small size (it is smaller than Earth's moon) and the unusual eccentricity and inclination of its orbit, many astronomers have questioned whether it should be regarded as a planet at all, suggesting that Pluto and its moon, Charon, are actually large Kuiper belt objects. See Table at solar system.
