Pluto, Hades, Aides, Aidoneus(noun)
(Greek mythology) the god of the underworld in ancient mythology; brother of Zeus and husband of Persephone
a small planet and the farthest known planet from the sun; it has the most elliptical orbit of all the planets
"Pluto was discovered by Clyde Tombaugh in 1930"
The ninth planet of the Solar System, the smallest (5700 km radius) and most distant from the sun. The suggestion has been made that it more closely resembles a large close comet than a planet. Its orbit has an eccentricity of 0.248, larger than that of any other planet; it varies from 4.44 to 7.37 billion km distance from the sun.
Etymology: [L., fr. Gr. Plou`twn.]
Greek and Roman god of the underworld.
Originally known as the ninth planet but reclassified in 2006 as a dwarf planet, the brightest and first known Kuiper belt object, represented by the symbol in astronomy and in astrology.

the son of Saturn and Rhea, brother of Jupiter and Neptune; the dark and gloomy god of the Lower World
Etymology: [L., fr. Gr. Plou`twn.]
Pluto, formal designation 134340 Pluto, is the second-most-massive known dwarf planet in the Solar System and the tenth-most-massive body observed directly orbiting the Sun. Originally classified as the ninth planet from the Sun, Pluto was recategorized as a dwarf planet and plutoid owing to the discovery that it is only one of several large bodies within the Kuiper belt. Like other members of the Kuiper belt, Pluto is composed primarily of rock and ice and is relatively small, approximately one-sixth the mass of the Earth's Moon and one-third its volume. It has an eccentric and highly inclined orbit that takes it from 30 to 49 AU from the Sun. This causes Pluto to periodically come closer to the Sun than Neptune. As of 2011, it is 32.1 AU from the Sun. From its discovery in 1930 until 2006, Pluto was classified as a planet. In the late 1970s, following the discovery of minor planet 2060 Chiron in the outer Solar System and the recognition of Pluto's relatively low mass, its status as a major planet began to be questioned. In the late 20th and early 21st centuries, many objects similar to Pluto were discovered in the outer Solar System, notably the scattered disc object Eris in 2005, which is 27% more massive than Pluto. On August 24, 2006, the International Astronomical Union defined what it means to be a "planet" within the Solar System. 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 hold that Pluto should continue to be classified as a planet, and that other dwarf planets should be added to the roster of planets along with Pluto.

god of the nether world, son of Kronos and Rhea, brother of Zeus and Poseidon, and husband of Persephone; on the dethronement of Kronos the universe was divided among themselves by the three brothers, Zeus assuming the dominion of the upper world and Poseidon that of the ocean, leaving the nether kingdom to him, a domain over which and forth of which he ruled with a greater and more undisputed authority than the other two over heaven, earth, and sea.
