Neptune is the eighth and most distant planet from the Sun in the Earth’s planetary group. It’s the fourth-most expansive planet by distance across and the third-most vast by mass. Neptune is 17 times the mass of Earth and is to some degree more enormous than its close-twin Uranus, which is 15 times the mass of Earth but not as dense.
On normal, Neptune circles the Sun at a separation of 30.1 AU, more or less 30 times the Earth–Sun separation. Named for the Roman lord of the ocean, its galactic image is ♆, a stylised form of the god Neptune’s trident.
Neptune was the first planet discovered by numerical forecast as opposed to by experimental recognition. Unforeseen updates in the circle of Uranus headed Alexis Bouvard to reason that its circle was subject to gravitational irritation by a unknown planet. Neptune was hence recognized on 23 September 1846 by Johann Galle within a level of the position anticipated by Urbain Le Verrier, and its most impressive moon, Triton, was uncovered quickly thereafter, however none of the planet’s remaining 12 moons were placed telescopically until the 20th century. Neptune has been visited by a single shuttle, Voyager 2, which flew by the planet on 25 Eminent 1989.

Is our Solar system unique in the Universe ? Until recently, astronomers could only guess whether other stars are orbited by planetary systems.
