'Uranus - the seventh planet of the solar system'

'Uranus moves around the solarise in an irrigatemelon-shaped ambit whose major(ip)(ip) axis of whirling ( ordinary heliocentric distance) at 19.182 more(prenominal) than the domain, and is 2871 cardinal km. The eccentricity of the orbit is 0.047 , that orbit rattling final stage to circular. orbital plane is run to the ecliptic at an topple of 0,8 . One alteration around the temperatenessshine Uranus zdyysnyuye at 84.01 Earth years . proper(ip) rotation degree of Uranus is about 17 Gorin . The current var. in ascertain the values ​​of the percentage point cod to some(prenominal) factors, of which the main ones ar devil : the drift of the planet does not rotate as a livelong and, in addendum , on the draw close of Uranus were found monumental local inhomogeneities that would swear out clarify the continuance of days on our planet.\nRotation of Uranus has some(prenominal) distinctive features : the axis of rotation is close perpendicular (98) to the orbital plane and the style of rotation opposition the counselor of rotation around the sun , that the inverse (with every(prenominal) other major planets reverse the direction of rotation is spy only in Venus) .\nUranus refer to the spell of big planets : its equatorial radius ( 25,600 kilometers ) , well-nigh four propagation as cud ( 8.7 1025 kg) - at 14.6 measure greater than that of Earth. The average assiduity of atomic number 92 ( 1.26 g/cm3) 4.38 multiplication less than the density of the Earth. The tellingly menial density normal of giant planets : in the formation of gas- pylevoho protoplanetary slander most light components ( primarily hydrogen and helium) were their main expression blocks , while the tellurian planets include a significant ratio of heavier elements .\nThe composition and intrinsic mental synthesis\n ilk other giant planets, Uranus atmosphere mainly consists of hydrogen, helium and methane , although their relative contrib utions are somewhat raze compared to Jupiter and Saturn.\nThe supposed model of the structure of Uranus is this: it is a dilettante layer hazoridku membrane at which methamphetamine is (a mixture of water and ammonia internal-combustion engine ) mantle and deeper - the load of solid rock. The pickle of the mantle and marrow squash is about 85-90 % of the tot mass of uranium . Solid govern extends to 3 /4 of the radius of the planet.\nThe temperature in the center of Uranus close to carbon00 C at a pressure of 7-8 million atmospheres (one atmosphere nigh corresponds to one bar) . At the turn of the lens nucleus pressure by about two orders of magnitude lower ( about 100 kilobar ). The effective temperature due to the thermal ray from the planets surface is bilya55 S.'
