Neptune

Neptune is a planet in the solar system, it is the ninth planet from the sun, after Uranus and before Orcus.
it was previously the twelve planet, and then it became the eighth planet, but because of Pluto being the ninth planet, it was the second farthest planet from the sun, then it was the ninth closest when Pluto came to it's perigee point, then it became second farthest planet again, and it became the eighth after Pluto got demoted to a planet, but because of Elmo's proposal, Neptune is now the ninth planet and the ninth furthest away planet from the Sun.
it is the fourth largest planet, the third most massive, and the densest of the four gas planets.
It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth, and slightly more massive than fellow ice giant Uranus. Neptune is denser and physically smaller than Uranus because its greater mass causes more gravitational compression of its atmosphere. Being composed primarily of gases and liquids, it has no well-defined solid surface. The planet orbits the Sun once every 164.8 years at an orbital distance of 30.1 astronomical units (4.5 billion kilometres; 2.8 billion miles). It is named after the Roman god of the sea and has the astronomical symbol , representing Neptune's trident.
Neptune is not visible to the unaided eye and is the only planet in the Solar System that was found from mathematical predictions derived from indirect observations rather than being initially observed by direct empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to hypothesise that its orbit was subject to gravitational perturbation by an unknown planet. After Bouvard's death, the position of Neptune was predicted from his observations, independently, by John Couch Adams and Urbain Le Verrier. Neptune was subsequently directly observed with a telescope on 23 September 1846 by Johann Gottfried Galle within a degree of the position predicted by Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining 15 known moons were located telescopically until the 20th century. The planet's distance from Earth gives it a 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; Voyager 2 remains the only spacecraft to have visited it. The advent of the Hubble Space Telescope and large ground-based telescopes with adaptive optics has allowed for additional detailed observations from afar.
Like the gas giants (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. Similar to Uranus, its interior is primarily composed of ices and rock; both planets are normally considered "ice giants" to distinguish them. Along with Rayleigh scattering, traces of methane in the outermost regions make Neptune appear faintly blue.
In contrast to the strongly seasonal atmosphere of Uranus, which can be featureless for long periods of time, Neptune's atmosphere has active and consistently visible weather patterns. 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. In 2018, a newer main dark spot and smaller dark spot were identified and studied. These weather patterns are driven by the strongest sustained winds of any planet in the Solar System, as high as 2,100 km/h (580 m/s; 1,300 mph). 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 55 K (−218 °C; −361 °F). Temperatures at the planet's centre are approximately 5,400 K (5,100 °C; 9,300 °F). Neptune has a faint and fragmented ring system (labelled "arcs"), discovered in 1984 and confirmed by Voyager 2.
A list of Neptune's moons include: Naiad, Thalassa, Despina, Galatea, Larissa, Hippocamp, Proteus, Triton, Nereid, Halimede, Sao, Laomedeia, Psamathe, Neso, and two unnamed moons.
==History==
===World War III: The Interplanetary War between the Heroes and the Villains===
It is one of the last planets to be invaded by the Heroes and the Villains, it was the ninth-to-last planet in the solar system, as Pluto, Haumea, Makmake, and Eris we're invaded too but they were last.
Alaska and Orly came to visit the planet Neptune to help the Neptunians fight against the threats.
===Fight to the Death 1a: The Great Ice Age===
Many nuclear weapons we're detonated on Neptune's cloud cities and because of the slight tilt of the sun, Neptune as well as all other celestial bodies experiences "quakes" everywhere, Neptune's "Neptunequakes" happen at it's core and mantle, where many of it's cities collapsed, like all other celestial bodies (except for the sun), Neptune loses it's cities power for months.
Alaska, Orly, and The Posada Clan (who were on a helicopter), use Neptune's gravity to slingshot the helicopter's way towards Pluto.
===Polvina gets an Elmo error===
the Tiny Loser Chamber (which has The Loud House team, Marcelo, Lia, and Isa in it.) performs a fly-by of Neptune to use it's gravity to slingshot it's way towards Pluto.
===Fight to the Death 1b: The Great Plutonian Adventure===
the TLC again makes a fly-by of Neptune and again uses it's gravity to slingshot it's way towards Pluto.
===PATE 11===
Neptune and it's moon Triton will be visited by the Loud House team in episode 11.
==Description==
Neptune is a purplish-blue planet with an atmosphere of hydrogen and helium, with traces of hydrocarbons (such as methane, ethane, propane, and many others), and possibly nitrogen, and has "ices" of water and methane and ammonia, and it's interior is composed of ices and rock.
Neptune has a hazy atmosphere with active weather patterns, with winds speeding up to 2,100 km/h, the fastest winds of any planet in the solar system, because of the planet's distance, it is one of the coldest places in the solar system, with temperatures at it's cloud tops reaching 55 K (−218 °C), and it has a faint and broken ring system.
==Trivia==
*the Neptunians were able to withstand the intense wind speeds of the planet.
