What is "neptune"

Neptune \Nep"tune\, prop. n. [L. Neptunus.]

1. (Rom. Myth.) The son of Saturn and Ops, the god of the waters, especially of the sea. He is represented as bearing a trident for a scepter.

2. (Astron.) The remotest major planet of our solar system, discovered -- as a result of the computations of Leverrier, of Paris -- by Galle, of Berlin, September 23, 1846. It is classed as a gas giant, and has a radius of 22,716 km and an estimated mass of

   1. 027 x 10^ 26 kg, with an average density of

   2. 27 g/cc. Its mean distance from the sun is about 5,000,000,000 km (3,106,856,000 miles), and its period of revolution is about 164.78 years.

      Neptune powder, an explosive containing nitroglycerin, -- used in blasting.

      Neptune's cup (Zo["o]l.), a very large, cup-shaped, marine sponge ( Thalassema Neptuni).

late 14c., "god of the sea," from Latin Neptunus, son of Saturn, brother of Jupiter, the Roman god of the sea (later identified with Greek Poseidon), probably from PIE root *nebh- "cloud" (source of Latin nebula "fog, mist, cloud;" see nebula), via a sense of "moist, wet." The planet so named was discovered by Galle in 1846. Until the identification of Pluto in 1930, it was the most distant planet known.

Neptune was the god of freshwater and the sea in Roman religion. He is the counterpart of the Greek god Poseidon. In the Greek-influenced tradition, Neptune was the brother of Jupiter and Pluto; the brothers presided over the realms of Heaven, the earthly world, and the Underworld.About the relationship of the lord of our earthly world with water(s) Bloch, p. 342-346, gives the following explanations:

1. Poseidon is originally conceived as a chtonic god, lord and husband of the Earth (for the etymology, epithtes γαιήοχος, he who possesses the Earth, εννοσίδας he who makes the Earth quake) with an equine form. He mates with Demeter under this form in the Arcadian myth from Thelpusa, they beget the racing horse Areion and the unnamed daughter of those mysteries (story in Pausanias VIII 25, 3).

2. Poseidon hippios (horse) is the god of Earth and as springs come from beneath the earth, this is also a metaphora (or better a figure) of the origin of life on Earth; the horse is universally considered as having a psychopompous character and Poseidon is known as tamer of horses (damaios) and father of Pegasus who with its hoof can open up a spring.

3. Poseidon is the god worshipped in the main temple of the Isle of Atlantis in the myth narrated by Plato in the dialogues Timaeus and Critias; there was also a hippodrome nearby.

4. The island was swallowed up by an earthquake caused by Poseidon himself. This factor would connect the power over earth and that over waters. The Greek had a memory of the explosion of the Island of Santorini and of the seaquake it provoked as well as other consequences affecting climate. Salacia was his consort.

Depictions of Neptune in Roman mosaics, especially those of North Africa, are influenced by Hellenistic conventions. Neptune was likely associated with fresh water springs before the sea. Like Poseidon, Neptune was worshipped by the Romans also as a god of horses, under the name Neptunus Equester, a patron of horse-racing.

Neptune, also called Poseidon, is a fictional character in Marvel Comics and is based on the Roman God with the same name. Neptune is the god of the sea in the Olympian pantheon, and the patron god of Atlantis.

Neptune is an Italian melodic death metal band from Verona, that was founded in 1999. Their influences are based upon melodic death metal acts such as; Hatesphere, In Flames, Soilwork, Dark Tranquillity, Disarmonia Mundi, At the Gates and The Haunted.

"Neptune" is the fourth single by Essex alternative metal band InMe. It is also the final single to be released from their debut album, Overgrown Eden. It was released on 14 April 2003 and reached number 46 in the UK Singles Chart.

Neptune is the second studio album by the London-based band The Duke Spirit and the last with the original lead guitarist, Dan Higgins. The album was released on 4 February 2008 on the independent label, You Are Here. The song "Lassoo" is used in the game Guitar Hero On Tour: Modern Hits for North America and the UK, and "Send a Little Love Token" is on the main set list for Guitar Hero 5 and Forza Motorsport 3.

Neptune is the sixth studio album by Japanese singer Toshinobu Kubota, released on July 1, 1992. The album charted at number 3 on the Oricon Monthly Albums chart and remained on the charts for total of 13 weeks. The album sold a total of 484,000 units, reaching double platinum certification.

Neptune is the eighth and farthest known planet from the Sun in the Solar System. In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. Neptune orbits the Sun once every 164.8 years at an average distance of . Named after the Roman god of the sea, its astronomical symbol is ♆ , a stylised version of the god Neptune's trident.

Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of the Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.

Neptune is similar in composition to Uranus, and both have compositions that differ from those of the larger gas giants, Jupiter and Saturn. Like Jupiter and Saturn, Neptune's atmosphere is composed primarily of hydrogen and helium, along with traces of hydrocarbons and possibly nitrogen, but contains a higher proportion of "ices" such as water, ammonia, and methane. However, its interior, like that of Uranus, is primarily composed of ices and rock, and hence Uranus and Neptune are normally considered " ice giants" to emphasise this distinction. Traces of methane in the outermost regions in part account for the planet's blue appearance.

In contrast to the hazy, relatively featureless atmosphere of Uranus, Neptune's atmosphere has active and visible weather patterns. For example, at the time of the Voyager 2 flyby in 1989, the planet's southern hemisphere had a Great Dark Spot comparable to the Great Red Spot on Jupiter. These weather patterns are driven by the strongest sustained winds of any planet in the Solar System, with recorded wind speeds as high as . Because of its great distance from the Sun, Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures at its cloud tops approaching . Temperatures at the planet's centre are approximately . Neptune has a faint and fragmented ring system (labelled "arcs"), which was first detected during the 1960s and confirmed by Voyager 2.

Neptune is the fourth album by The Northern Pikes released in 1992. This was the band's last studio album until they reformed in 1999.

Although "Twister" and "Everything" were released as proper singles, with "Twister" becoming a moderate hit. The song "Believe" was released as a promotional single, and was a top 40 hit. Meanwhile, "Everything" failed to chart – instead, the b-side "Worlds Away" picked up airplay and peaked at #40 on the Canadian singles charts.

The album was certified Gold in Canada by the Canadian Recording Industry Association on December 10, 1992.

The album features co-vocals by Margo Timmins of Cowboy Junkies on two songs, and the playing of Ken Greer of Red Rider on two songs.
