Neptune Planet

Neptune PlanetAccording to the position structure in our solar system the Neptune planet comes under eighth planet and one of the farthest planet from our sun. The name Neptune comes from the Roman God of the sea. As compare to the diameter is comes under fourth largest planet and as compared with the mass it comes under third largest planet in our solar system. As compare to the earth, Neptune plant is seventeen times the mass of our Earth & is little more massive than Uranus planet which is fifteen times the mass of the earth but is not as dense. The Neptune planet use to orbit the sun at the distance of 30.1 AU on average calculation and approx. the thirty times the Earth-Sun distance. The astronomical symbol for representing the Neptune planet is by ♆, stylized version of god Neptune's trident.

Neptune PlanetThe Neptune planet was firstly discovered in 1846, September 23 by the mathematical prediction rather than by the empirical observation. Neptune planet was first planet which is found by the mathematical prediction. There was an unexpected change in the orbit of Uranus planet which led Alexis Bouvard to deduce that orbit was subject to gravitational perturbation by the unknown planet. Johann Galle observed Neptune planet subsequently within the degree of position predicted by the Urbain Le Verrier & the it’s largest moon, Triton, was discovered shortly, though none of planet’s remaining twelve moons were located telescopically till 20th century. In the year 1989 August 25 Voyager 2 towards the Neptune planet and this is only one spacecraft to visit the planet.

Neptune PlanetNeptune planet has same or the similar type of composition as the Uranus planet have but both planet has differ composition than the other giant planet Saturn and Jupiter. The atmosphere composition of Neptune planet is somehow similar to that of Saturn and Jupiter therefore it is composed of helium and hydrogen together with the hydrocarbons & the possibly nitrogen. The planet contains the higher proportion of Ices such as the water, methane and the ammonia. Sometime the Uranus planet and the Neptune planet is also categorize as the ice giants by the astronomers in order to emphasize these distinction. The internal part or the interior of the planet Neptune is as same as of the planet Uranus which is primarily composed of rocks and ice. Outermost regions of the planet traces methane for blue appearance of the planet.

In opposite to relatively featureless atmosphere of the planet Uranus, the atmosphere of Neptune planet is notable for it’s active & visible weather patterns. For e.g: During the time of Voyager 2flyby in the year 18989, the southern hemisphere of the planed possessed the Great Dark Spot as comparable to the Great Red Spot on the planet Jupiter. These weather patterns were driven by strongest sustained winds of the planet in our Solar system, with the speed of wind recorded as high as 2100 km/h. Due to the position of the planet is very away from our sun the outer atmosphere of the Neptune planet is one of the coldest planet in our solar system with the temperature of -218 degree Celsius (55 K) at its cloud tops. The temperature at the center of the planet is approximately about 5400 K (5000 degree Celsius). Neptune planet has a faint & fragmented ring system which may have been detected during the year in 1960s but indisputable evidence was only confirmed by the Voyager 2 in 1989.
