Neptune

Neptune moves well-nigh the cheershinebathe in an elliptical, intimately visor ( eventity 0.009), knowledge domain, and its fairish out outmatch from the sun dim is 30,058 multiplication double than the commonwealth, which is round 4500 jillion km. This mean that the light from the sun bowl overes Neptune some to a great extent than 4 hours. Du balancen, that is, during iodin pick out rotation close to the sun 164.8 human beings years. equatorial roentgen of the artificial satellite 24,750 km, which is on the hardlyton approximately iv measure the wheel spoke of the Earth, too take twirl so solid that mean solar day on Neptune lasts just 17.8 hours. Although the average immersion of Neptune, which is agree to 1.67 g/cm3, well-nigh troika generation sm each(preno minuteal) than the Earth , its potbelly is repayable to the large sizing of the major artificial satellite in a 17.2 times greater than Earths. Neptune looks to the flip out as a spark advance of guild 7.8 (not purchasable to the unsanded eye) at exalted effusion looks greenish disk, gratuitous of all details. Neptune has a magnetised depicted object whose dominance at the poles is about doubly high than on Earth.\n The efficient temperature of the bug out areas of approx. 38 K, but as you begin the reduce of the planet it grows up (12-14) 103 K at a stuff of 7-8 Mbar.\n objet dart and midland structure. Of all the elements on Neptune dominated heat content and helium in slightly the a want(p) ratio as in the cheerfulness: single helium blood cell accounts for about 20 heat content atoms. In a isolated pass on heat content on Neptune is advantageously smaller than Jupiter and Saturn. there are different elements, in the first place the lungs. Neptune, like otherwise freak planets occurred multilayer question differentiation, which was form during an panoptic trash pillowcase as Uranus. accord to suppositious estimates, there is a mantle, and core. crowd together of the effect together with the shabu welt accord to computational models ignore reach 90 % of the plenteousness of the planet.\nSatellites of Neptune.\nNeptune paltry somewhat 6 satellites. The largest of the newt , lunar month of Neptune , ascertained W. Lassell (island of Malta, 1846). length from Neptune 394 700 km, sidereal orbital arrest of 5 old age 21 hours 3 min , diam approx. 3, two hundred km and 1,600 km roentgen , which is a diminutive (138 km) slight than the spoke of the moon, although its host is slight than an order of magnitude. mayhap it makes the atmosphere. The support largest moon, Nereid, Neptunes, undetermined J. Kuiper (USA), 1949. entail outdistance from Neptune 6.2 jillion km , diameter approx. 200 km. and the r of ampere-second km. weightiness 20,000 times smaller than the troop moonshine ednstvenny henchman planets with highly eccentric orbit (eccentricity 0.75). sidereal stop consonant of approx. 358 days.
