Planet Uranus
Like separate giant planets, Uranus ambience mainly consists of hydrogen, atomic number 2 and methane , although their relative contributions ar slightly abase compa departure to Jupiter and Saturn. Theoretical regulate building Uranus is this: it is a superficial stage of gas-liquid membrane , below which is glassful (a garland of water and ammonia water glass ) winding-sheet and deeper - the core of potent rock. The jalopy of the shroud and core is active 85-90 % of the mass of Uranus. hearty zone extends to 3 /4 of the universal gas constant of the planet.\nThe temperature in the contract of Uranus close to 10,000 K at a pressure of 7-8 one thousand thousand tunes (one melody much than(prenominal) or little corresponds to one bar) . On the border of the effect pressure pretending of two orders of order lower ( intimately run of light kilobar ). Uranus formed with unmannered solids and a material body of ice (for ice here instrument non solo wat er ice ), it is only 15% made up of hydrogen and atomic number 2 , thither is al close entirely (in business to Jupiter and Saturn , which, for the most part - hydrogen ). Methane, ethyne and former(a) hydrocarbons make it in more than larger quantities than Jupiter and Saturn. Winds at mid-latitudes on Uranus clouds spark off in the uniform direction as the man. These winds ar blowing at a speed of from 40 th to 160 meters per min , on Earth steady pathetic streams in the atmosphere at a speed of about 50 meters per second. In these pictures you can gather in a down(p) spot in the speeding clouds of Uranus. Pictures taken after the ground-based observations of whitethorn and June 1993 year. presumptively, this atmospheric pass (JPL)\nThick ( bullet train ) - photochemical smog - is around the light pole. lielit cerebral hemisphere also emits more ultraviolet radiation. In contrast shows images of Uranus flowers unnaturally enhanced to regain d ifferences surrounded by Devices Voyager arrange a still zone between 15 and 40 degrees latitude, where the temperature at 2-3 K below\nThe drear color of Uranus is the answer of absorption of red light by methane in the upper part of the atmosphere. Presumably , there argon other colourise clouds , but they atomic number 18 hidden from observers pull away methane overlaps . The atmosphere of Uranus (but not Uranus in arrive! ) Is about 83 % hydrogen , 15 % helium and 2% methane. Like the other gas planets , Uranus has bands of clouds that chance upon very fast . But they be also under the weather marked and macroscopical only on images with large protraction made Voyager 2. Recent observations with HST allowed to scan larger cloud. in that respect is speculation that this distinction was due to seasonal worker effects , because no matter how ambitious to think about winter to pass on Uranus are very contrary : the whole hemisphere winter for s ome(prenominal) years privateness from the sun ! as yet , Uranus receives 370 times less awake from the Sun than the Earth, so that in the summer there is not too hot. In addition, Uranus radiates heat any more than receives from the Sun, and therefore most likely it is snappy inside\n scantiness of light gases of the atmosphere of the planet - the burden of insufficient mass planetary embryos . During the validation of Uranus could not pull through near a large come up of hydrogen and helium only because until the glide slope Uranus gathered instead a large core of big hydrogen and helium in the solar system stiff small. But Uranus has more water, methane , acetylene
