Neptune
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. [c] Neptune orbits the Sun
once every 164.8 years at an average distance of 30.1 astronomical
units (4.50 × 10 9 km). It is named after the Roman god of the sea
and has the astronomical symbol ♆, a stylized 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's
composition is similar to that of Uranus and unlike those of the
larger gas giants, Jupiter and Saturn. Like Jupiter's and Saturn's,
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, which is why Uranus and Neptune are
normally considered
"ice giants"
to emphasize 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 2,100 kilometres per hour (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).
Temperatures at the
planet's centre are approximately 5,400 K (5,100 °C). Neptune has a
faint and fragmented ring system (labelled "arcs"), which
was first detected during the 1960s and confirmed by Voyager 2.
