Neptune is about four times wider than Earth. Number Eight. Neptune is 30 AU from the Sun. Earth = 1 AU. A Neptunian Year. Neptune takes 165 Earth years to go around the Sun.
Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest.
2 days ago · Neptune, third most massive planet of the solar system and the eighth and outermost planet from the Sun. Because of its great distance from Earth, it cannot be seen with the unaided eye. With a small telescope, it appears as a tiny, faint blue-green disk. It is designated by the symbol ♆.

Sep 21, 2022 · Most striking in Webb’s new image is the crisp view of the planet’s rings – some of which have not been detected since NASA’s Voyager 2 became the first spacecraft to observe Neptune during its flyby in 1989. In addition to several bright, narrow rings, the Webb image clearly shows Neptune’s fainter dust bands.
Neptune: Exploration. Galileo recorded Neptune as a fixed star during observations with his small telescope in 1612 and 1613. More than 200 years later, the ice giant Neptune became the first planet located through mathematical predictions rather than through regular observations of the sky.

Neptune (Nep´tune), god of the sea, was a son of Saturn and Cybele, and brother to Jupiter and Pluto.He quarreled with Jupiter because he did not consider that the dominion of the sea was equal to Jupiter’s empire of heaven and earth; and he was banished from the celestial regions, after having conspired with Pluto to dethrone Jupiter.
NEPTUNE is the largest installation on the Ocean Networks Canada network of ocean observatories. Since December 2009, it has allowed people to "surf" the seafloor while ocean scientists run deep-water experiments from labs and universities around the world. Along with its sister project, VENUS, NEPTUNE offers a unique approach to ocean science.
Neptune ( Latin: Neptūnus [nɛpˈtuːnʊs]) is the Roman god of freshwater and the sea [2] in Roman religion. He is the counterpart of the Greek god Poseidon. [3] . In the Greek-inspired tradition, he is a brother of Jupiter and Pluto; the brothers preside over the realms of heaven, the earthly world (including the underworld ), and the seas. [4] .
