Pluto |ˈploōtō|
1 Greek Mythology the god of the underworld. Also called Hades .
2 Astronomy the most remote known planet of the solar system, usually ninth in order from the sun, discovered in 1930 by Clyde Tombaugh.
Pluto usually orbits beyond Neptune at an average distance of 5,900 million km from the sun, although its orbit is so eccentric that at perihelion it is closer to the sun than Neptune (as in 1979–99). Pluto is smaller than earth's moon (diameter about 2,250 km), but it was discovered in 1978 to have its own satellite (Charon), which is so large that the pair should properly be regarded as a double planet.
ORIGIN via Latin from Ploutōn, the Greek name of the god of the underworld.

A dwarf planet that until 2006 was classified as the ninth planet in our solar sytem, having a sidereal period of revolution about the sun of 248.5 years, 4.4 billion kilometers (2.8 billion miles) distant at perihelion and 7.4 billion kilometers (4.6 billion miles) at aphelion, and a diameter less than half that of Earth.

这是关于他的最新解释，前面说他是行星，但后来改了。并介绍了他的特征，希望有所帮助：
Pluto, formal designation 134340 Pluto, is the second-largest known dwarf planet in the Solar System (after Eris) and the tenth-largest body observed directly orbiting the Sun. Originally classified as a planet, Pluto is now considered the largest member of a distinct population called the Kuiper belt.
Like other members of the Kuiper belt, Pluto is composed primarily of rock and ice and is relatively small: approximately a fifth the mass of the Earth's Moon and a third its volume. It has an eccentric and highly inclined orbit that takes it from 30 to 49 AU (4.4–7.4 billion km) from the Sun. This causes Pluto periodically to come closer to the Sun than Neptune.
Pluto and its largest moon, Charon, are sometimes treated together as a binary system because the barycentre of their orbits does not lie within either body. The International Astronomical Union (IAU) has yet to formalise a definition for binary dwarf planets, and until it passes such a ruling, Charon is classified as a moon of Pluto. Pluto has two known smaller moons, Nix and Hydra, discovered in 2005. Like Uranus, Pluto rotates on its "side" relative to its orbital plane, and the Pluto-Charon system does also.
From its discovery in 1930 until 2006, Pluto was considered the Solar System's ninth planet. In the late 1970s, following the discovery of minor planet 2060 Chiron in the outer Solar System and the recognition of Pluto's very low mass, its status as a major planet began to be questioned. Later, in the early 21st century, many objects similar to Pluto were discovered in the outer solar system, notably the scattered disc object Eris, which is 27% more massive than Pluto. On August 24, 2006, the IAU defined the term "planet" for the first time. This definition excluded Pluto as a planet, and added it as a member of the new category "dwarf planet" along with Eris and Ceres. After the reclassification, Pluto was added to the list of minor planets and given the number 134340. A number of scientists continue to hold that Pluto should be classified as a planet.
