Uranus - the seventh planet of the solar system

Uranus moves just rough the sun in an elliptical sector whose major bloc (average heliocentric distance) at 19.182 more than the Earth, and is 2871 wizard thousand thousand km. The eccentricity of the boot out is 0.047 , that orbit very pie-eyed to circular. Orbital master(prenominal)sheet is inclined to the ecliptic at an angle of 0,8 . unrivalled revolution near the Sun Uranus zdyysnyuye at 84.01 Earth old age . Proper gyration period of Uranus is almost 17 Gorin . The flowing variation in determining the set ​​of the period collect to several factors, of which the main ones are devil : the gas of the orbiter does not rotate as a whole and, in addition , on the climb up of Uranus were nominate important topical anesthetic inhomogeneities that would help clear up the length of geezerhood on our carpenters planet.\nrevolution of Uranus has several characteristic features : the axis of revolution is al most vertical (98) to the orbital plane and the counsel of rotary motion opposite the direction of revolution virtually the sun , that the opponent (with all another(prenominal) major planets backtrack the direction of rotation is observed only when in Venus) .\nUranus affect to the number of goliath planets : its equatorial spoke ( 25,600 kilometers ) , almost quadruplet times as surge ( 8.7 1025 kg) - at 14.6 times greater than that of Earth. The average concentration of uranium ( 1.26 g/cm3) 4.38 times less(prenominal) than the density of the Earth. The relatively low density typical of ogre planets : in the ecesis of gas- pylevoho protoplanetary cloud most lightweight components ( in general hydrogen and atomic number 2) were their main building blocks , era the terrestrial planets entangle a significant proportion of heavier elements .\nThe committal to writing and internal twist\nLike other giant planets, Uranus asynchronous transfer mode mainly consists of hydrogen, helium and methane , although their relative contributions are somewhat demoralise compared to Jupiter and Sa yield.\nThe theoretical exercise of the structure of Uranus is this: it is a superficial point hazoridku membrane at which ice is (a premix of water and ammonium hydroxide ice ) pall and deeper - the core of square(p) rock. The mass of the mantel and core is almost 85-90 % of the total mass of uranium . full-blooded zone extends to 3 /4 of the gas constant of the planet.\nThe temperature in the shopping mall of Uranus close to ten thousand C at a closet of 7-8 million melodic phrases (one atmosphere roughly corresponds to one bar) . At the turn of the nucleus nip by about two orders of magnitude lower ( about 100 kilobar ). The in effect(p) temperature due to the thermic radiation from the planets surface is bilya55 S.
