Description

The average distance between Neptune and the Sun is 4.5 billion km (about 30.1 astronomical units (AU)), and it completes an orbit on average every 164.79years, subject to a variability of around ±0.1years. The perihelion distance is 29.81AU; the aphelion distance is 30.33AU. [g]

One might be tempted to say "except 'Earth'", which in the English language is the name of a Germanic deity, Erda. The IAU policy is that one may call the Earth and the Moon by any name commonly used in the language being used. Contrary to common use by science fiction writers, 'Terra' and 'Luna' are not the official names of planet Earth and its moon. See the wikipedia article Earth for references.In 1821, Alexis Bouvard published astronomical tables of the orbit of Neptune's neighbour Uranus. [34] Subsequent observations revealed substantial deviations from the tables, leading Bouvard to hypothesise that an unknown body was perturbing the orbit through gravitational interaction. [35] In 1843, John Couch Adams began work on the orbit of Uranus using the data he had. He requested extra data from Sir George Airy, the Astronomer Royal, who supplied it in February1844. Adams continued to work in 1845–1846 and produced several different estimates of a new planet. [36] [37] Urbain Le Verrier In 1989, the Great Dark Spot, an anticyclonic storm system spanning 13,000km ×6,600km (8,100mi ×4,100mi) [101] was discovered by NASA's Voyager 2 spacecraft. The storm resembled the Great Red Spot of Jupiter. Some five years later, on 2 November 1994, the Hubble Space Telescope did not see the Great Dark Spot on the planet. Instead, a new storm similar to the Great Dark Spot was found in Neptune's northern hemisphere. [105]

The spacecraft verified the existence of a magnetic field surrounding the planet and discovered that the field was offset from the centre and tilted in a manner similar to the field around Uranus. Neptune's rotation period was determined using measurements of radio emissions and Voyager 2 also showed that Neptune had a surprisingly active weather system. Six new moons were discovered, and the planet was shown to have more than one ring. [144] [169]The dipole component of the magnetic field at the magnetic equator of Neptune is about 14 microteslas (0.14 G). [93] The dipole magnetic moment of Neptune is about 2.2×10 17T·m 3 (14μT· R N 3, where R N is the radius of Neptune). Neptune's magnetic field has a complex geometry that includes relatively large contributions from non-dipolar components, including a strong quadrupole moment that may exceed the dipole moment in strength. By contrast, Earth, Jupiter and Saturn have only relatively small quadrupole moments, and their fields are less tilted from the polar axis. The large quadrupole moment of Neptune may be the result of an offset from the planet's centre and geometrical constraints of the field's dynamo generator. [94] [95]

A second symbol, an ‘LV’ monogram for 'LeVerrier', analogous to the ‘H’ monogram for Uranus. It was never much used outside of France and is now archaic.Neptune's mass of 1.0243 ×10 26kg [7] is intermediate between Earth and the larger gas giants: it is 17 times that of Earth but just 1/19th that of Jupiter. [f] Its gravity at 1 bar is 11.15m/s 2, 1.14 times the surface gravity of Earth, [68] and surpassed only by Jupiter. [69] Neptune's equatorial radius of 24,764km [10] is nearly four times that of Earth. Neptune, like Uranus, is an ice giant, a subclass of giant planet, because they are smaller and have higher concentrations of volatiles than Jupiter and Saturn. [70] In the search for exoplanets, Neptune has been used as a metonym: discovered bodies of similar mass are often referred to as "Neptunes", [71] just as scientists refer to various extrasolar bodies as "Jupiters". Neptune's spectra suggest that its lower stratosphere is hazy due to condensation of products of ultraviolet photolysis of methane, such as ethane and ethyne. [21] [28] The stratosphere is also home to trace amounts of carbon monoxide and hydrogen cyanide. [21] [89] The stratosphere of Neptune is warmer than that of Uranus due to the elevated concentration of hydrocarbons. [21] Neptune is the eighth and most distant planet from the Sun. That means Uranus is Neptune’s only neighboring planet. For a timeline of discovery dates, see Timeline of discovery of Solar System planets and their moons. An annotated picture of Neptune's many moons as captured by the James Webb Space Telescope. The bright blue diffraction star is Triton, Neptune's largest moon. The outermost ring, Adams, contains five prominent arcs now named Courage, Liberté, Egalité1, Egalité2 and Fraternité (Courage, Liberty, Equality and Fraternity). [155] The existence of arcs was difficult to explain because the laws of motion would predict that arcs would spread out into a uniform ring over short timescales. Astronomers now estimate that the arcs are corralled into their current form by the gravitational effects of Galatea, a moon just inward from the ring. [156] [157]

The flyby also provided the first accurate measurement of Neptune's mass which was found to be 0.5 percent less than previously calculated. The new figure disproved the hypothesis that an undiscovered Planet X acted upon the orbits of Neptune and Uranus. [170] [171] At high altitudes, Neptune's atmosphere is 80% hydrogen and 19% helium. [28] A trace amount of methane is also present. Prominent absorption bands of methane exist at wavelengths above 600nm, in the red and infrared portion of the spectrum. As with Uranus, this absorption of red light by atmospheric methane is part of what gives Neptune its blue hue, [82] although Neptune's blue differs from Uranus's milder light blue due to concentrated haze in the latter atmosphere.

This trend was first seen in 1980. The long orbital period of Neptune results in seasons lasting forty years. [104] Storms In 1845–1846, Urbain Le Verrier, independently of Adams, developed his own calculations but aroused no enthusiasm in his compatriots. In June1846, upon seeing LeVerrier's first published estimate of the planet's longitude and its similarity to Adams's estimate, Airy persuaded James Challis to search for the planet. Challis vainly scoured the sky throughout August and September. [35] [38] Challis had, in fact, observed Neptune a year before the planet's subsequent discoverer, Johann Gottfried Galle, and on two occasions, 4 and 12 August 1845. However, his out-of-date star maps and poor observing techniques meant that he failed to recognise the observations as such until he carried out later analysis. Challis was full of remorse but blamed his neglect on his maps and the fact that he was distracted by his concurrent work on comet observations. [39] [35] [40]
