This is Neptune.The eighth planet from the sun.

Neptune is a landless gas giant. Like Jupiter,Saturn,and Uranus,it is a gas liquid world.Not much sunlight reaches Neptune .Being so far from the sun makes it a cold,dark place.But Neptune is a planet full of surprises.Where are the fastest winds in the solar system?Where do giant swirling storms  suddenly appear and disappear?Neptune.Even its beautiful bright blue color is surprising .Does your kitchen`s stove use natural gas ,or methane?Methane makes both Uranus and Neptune blueish.No one knows why Neptune is a brighter blue-at least not yet.[ Neptune has a thick atmosphere of gases ,with liquid underneath. Scientists think it has a solid core of rock and ice.]


English astronomer John Couch Adams was the first to solve the planetary math problem in 1845,but no one took him seriously enough enough to start looking for an eighth planet.Meanwhile Urbain J.J Le Verrier figured it out ,too,and told some astronomers where to look. On September 23,1846,German astronomer Johann Galle Le Verrier`s predictions to find an eighth planet. the discoverers agreed to  name it after the Roman god of the deep blue sea .Since it`s discovery 167 years ago


*Neptune is the farthest planet in our solar system.It`s about 30 times as far from the sun as Earth.                                                                                                                                            * Neptune receives about 900 times less sunlight than Earth.                                                     *Johann Galle first observed Neptune in 1846 using a telescope  and  Le Verries predicted location

Triton, Nereid, Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Halimende , Psamathe, Sao, Laomedeia, and Neso. Their names come from sea of gods and their relatives in Greek mythology,                                               * Most of Neptune`s moons are small,and there are likely more undiscovered small ones.
