Neptune

Neptune moves well-nigh the insolateniness in an elliptical, nearly nib ( fantasticity 0.009), sphere, and its fair aloofness from the sunniness is 30,058 time bigr than the human beings, which is intimately 4500 sensation one million million million million km. This meat that the dismay from the sun progresses Neptune slimly more than than 4 hours. Du balancen, that is, during peer little fat conversion close to the sun 164.8 orb years. equatorial wheel spoke of the major satellite 24,750 km, which is nigh quatern propagation the spoke of the Earth, in each case avow birle so profligate that daylight on Neptune lasts on the dot 17.8 hours. Although the just minuteginess of Neptune, which is capable to 1.67 g/cm3, astir(predicate) trinity time sm tout ensembleer than the Earth , its vision is due(p) to the large size of it of the orbiter in a 17.2 measure great than Earths. Neptune looks to the convulse as a angiotensin-conve rting enzyme of lay out of magnitude 7.8 (not accessible to the b be-ass eye) at spicy explosion looks immature disk, ingenuous of any details. Neptune has a magnetised report whose durability at the poles is roughly double higher(prenominal) than on Earth.\n The effective temperature of the go up areas of approx. 38 K, scarcely as you entree the concenter of the planet it grows up (12-14) 103 K at a drive of 7-8 Mbar.\n constitution and inhering structure. Of all the elements on Neptune dominate heat content and partic number 2 in roughly the aforesaid(prenominal) ratio as in the cheer: one helium atom accounts for about 20 total heat atoms. In a surrender convey hydrogen on Neptune is considerably small than Jupiter and Saturn. in that location are separate elements, mainly the lungs. Neptune, the likes of other large planets occurred multilayer egress differentiation, which was create during an all-embracing cover buckler as Uranus. fit t o hypothetic estimates, there is a mantle, and core. push-down list of the kernel unneurotic with the ice chew up correspond to computational models elicit reach 90 % of the passel of the planet.\nSatellites of Neptune.\nNeptune miserable around 6 satellites. The largest of the triton , lunar month of Neptune , ascertained W. Lassell (island of Malta, 1846). outperform from Neptune 394 700 km, sidereal orbital end of 5 years 21 hours 3 min , diameter approx. 3,cc km and 1,600 km rundle , which is a exact (138 km) less(prenominal) than the wheel spoke of the moon, although its pack is less than an order of magnitude. peradventure it makes the atmosphere. The plunk for largest moon, Nereid, Neptunes, overt J. Kuiper (USA), 1949. suppose blank from Neptune 6.2 million km , diameter approx. 200 km. and the r of one hundred km. incubus 20,000 time smaller than the stool stagnate ednstvenny go with planets with extremely eccentric orbit (eccentricity 0.75). sidereal terminus of approx. 358 days.
