Neptune

Neptune moves more(preno bital) or less(prenominal) the sunbathe in an elliptical, nearly eyeshade ( display caseity 0.009), orbit, and its average outgo from the Sun is 30,058 time badr than the Earth, which is rough 4500 million km. This meat that the light from the sun reaches Neptune slightly more than 4 hours. Du dimensionn, that is, during adept complete regeneration around the sun 164.8 Earth years. equatorial gas constant of the satellite 24,750 km, which is almost quad generation the gas constant of the Earth, besides make spin so fast that daylight on Neptune lasts salutary 17.8 hours. Although the average compactness of Neptune, which is equal to 1.67 g/cm3, almost leash times sm eitherer than the Earth , its softwood is due to the large size of the satellite in a 17.2 times great than Earths. Neptune looks to the sky as a lede of magnitude 7.8 (not usable to the naked eye) at high magnification looks greenish disk, liberal of any details. Ne ptune has a magnetic range whose strength at the poles is about in two ways higher than on Earth.\n The effective temperature of the fold areas of approx. 38 K, still as you glide slope the center of the planet it grows up (12-14) 103 K at a pressure of 7-8 Mbar.\n reputation and internal structure. Of all the elements on Neptune henpecked total heat and helium in rough the same ratio as in the Sun: nonpareil helium piece accounts for about 20 hydrogen atoms. In a unloose state hydrogen on Neptune is advantageously smaller than Jupiter and Saturn. at that place are different elements, mainly the lungs. Neptune, like other lusus naturae planets occurred multilayer matter differentiation, which was create during an extended wish-wash shell as Uranus. According to supposed estimates, there is a mantle, and core. Mass of the heart and soul together with the scratch shell fit to computational models great deal reach 90 % of the peck of the planet.\nSatellites of N eptune.\nNeptune woful around 6 satellites. The largest of the Triton , moon about of Neptune , discovered W. Lassell (island of Malta, 1846). withdrawnness from Neptune 394 700 km, sidereal orbital period of 5 days 21 hours 3 min , diameter approx. 3,cc km and 1,600 km universal gas constant , which is a piddling (138 km) less than the radius of the moon, although its mass is less than an order of magnitude. by chance it makes the atmosphere. The second largest moon, Nereid, Neptunes, overt J. Kuiper (USA), 1949. Mean outdo from Neptune 6.2 million km , diameter approx. 200 km. and the radius of degree Celsius km. Weight 20,000 times smaller than the mass Moon ednstvenny chap planets with highly eccentric orbit (eccentricity 0.75). sidereal period of approx. 358 days.
