Neptune 
c.1385, from L. Neptunus, the Roman god of the sea (later identified with Gk. Poseidon), probably from PIE base *(e)nebh- "moist" (cf. L. nebula "fog, mist, cloud;" see nebula). The planet so named was discovered by Galle in 1846. Until the identification of Pluto in 1930, it was the most distant planet known. Neptunian (1794) in the geological sense refers to actions of water; usually opposed to volcanic or plutonic.

Neptune    Audio Help   (něp'tn')  Pronunciation Key 
The eighth planet from the Sun and the fourth largest, with a diameter almost four times that of Earth. Neptune is a gas giant with a very active weather system, exhibiting extremely long and powerful storms with the fastest winds observed in the solar system. Neptune's axis is tilted 28.8° from the plane of its orbit, and its summer and winter seasons each last 40 years. For a period of 20 years out of every 248, Pluto's highly elliptical orbit crosses within that of Neptune, making Neptune the farthest planet from the Sun during that period. Neptune has four faint rings and 13 known moons and appears blue due to the absorption of red light by the methane within its atmosphere. See Table at solar system.

Neptune

In astronomy, a major planet, the eighth planet from the sun. Neptune is named for the Roman god of the sea. Neptune is similar in size and composition to Uranus. It is usually visible only through a telescope and was discovered in the 1840s. For a period ending in 1999, Pluto's orbit took it inside the orbit of neptune. (See solar system; see under “Mythology and Folklore.”)

Note: Some astronomers have suggested that Pluto is not a planet in the usual sense but is an object more like an asteroid, and that Neptune, therefore, is actually the outermost planet.
