Neptune.jpg

Neptune is named after the Roman god of the sea, and was the first planet to be predicted by mathematical prediction discovered by Urbain Le Verrier, John Couch Adams, Johann Galle in September 23, 1846. Neptune has been visited by only one spacecraft, voyager 2 which flew by the planet on August 25, 1989. Neptune is similar in composition to Uranus, and both have compositions which differ from those of the largest gas giants, Jupiter and Saturn. Neptune's atmosphere, while similar to Jupiter's and Saturn's in that it is composed primarily of hydrogen and helium, along with traces of hydrocarbons and possibly nitrogen, contains a high proportion of "ice" such as water, ammonia and methane. astronomers sometimes categorize Uranus and Neptune as "ice giants" in order to emphasize these distinctions. the interior of Neptune, like that of Uranus, is primarily composed ices and rock. traces of methane in the outermost regions in part account for the planet's blue appearance.
