Planet Neptune, The Blue of Space

Neptune is the furthest eighth planet when viewed from the Sun. Neptune has an average distance with the Sun of 4,450 million km. Neptune has a diameter of 49,530 km and has a mass of 17.2 Earth masses. The planet’s rotation period is 16.1 hours, while the revolutionary period is 164.8 years. The shape of the planet is similar to that of the Moon with a thin silicate layer. The composition of the planet is iron and other heavy elements. The planet Neptune has eight satellites, including Triton, Proteus, Nereid and Larissa. Structure In Neptune Composition similar to Uranus formed by ice and stone with about 15% hydrogen and a little helium. Like Uranus But unlike Jupiter and Saturn, He can not have different internal layers. Neptune has a small nucleus (About the size of Earth) consists of rocky material. The atmosphere is mostly hydrogen and helium with a small amount of different methane-gas. Neptune’s Atmospheric Structure consists of 80 ± 3.2% Hydrogen, 19 ± 3.2% Helium, 1.5 ± 0.5% Methane and the other is ice similar to Uranus. The blue color of Neptune is largely the result of absorbing the red light from methane in the atmosphere. But there are also some unknown components, which give the blue color of clouds. Neptune has fast winds The solar system at a speed of 2000 km / h. Like Jupiter and Saturn, Neptune has an internal heat source, it emits twice the energy it receives from the Sun

Planet Rings Cheap Offers

Neptune has a thin dust ring that was discovered in 1989 by Voyoger 2. Neptune’s rings are almost identical to those of Jupiter’s rings which are almost invisible, unlike rings on Saturn or Uranus. The rings of Neptune from the nearest are Galle, LeVerrier, Lassell, Arago and Adams. Besides that there is still another dark ring that and still do not have a name whose orbit cuts the moon’s orbit of Neptune Galatea. In the dark ring area of ​​Neptune besides Galatea there are still three months of Neptune, namely Naiad, Thalassa, and Despina. In 1968, through the occult star for the first time the Neptune ring was detected, but at that time it was still not realized that it was a ring. The new Neptune Ring proved its existence when Voyoger 2 made a cross-flight in 1989. The Neptune rings have very dark particles, the amount of dust in this Neptune ring reaches 20-70%. High enough dust content is found in Galle and LeVerrier which reach 40 – 70%, while the lowest dust content found in Lassell is only about 20-40% only. The ring of Neptune is thought to be very young, younger than the age of our solar system. It is estimated that this ring is formed from an inner satellite collision in Neptune and then forms a dust belt in the area and eventually becomes the planet Neptune’s ring.
