Uran jest si\u00f3dm\u0105 planet\u0105 licz\u0105c od S\u0142o\u0144ca. Odkry\u0142 j\u0105 William Herschel w 1781 roku.<\/p>\n<\/div>\n

Uran znajduje si\u0119 w odleg\u0142o\u015bci ponad 2 800 milion\u00f3w km od S\u0142o\u0144ca. W tej odleg\u0142o\u015bci temperatura wierzcho\u0142k\u00f3w jego chmur wynosi -214 stopni C. Porusza si\u0119 do\u015b\u0107 wolno i ma przed sob\u0105 d\u0142ug\u0105 drog\u0119 do pokonania, wi\u0119c ka\u017cdy obieg wok\u00f3\u0142 S\u0142o\u0144ca trwa 84 lata.<\/p>\n

Uran to gigantyczna planeta, trzecia co do wielko\u015bci w naszym Uk\u0142adzie S\u0142onecznym. W jej wn\u0119trzu zmie\u015bci\u0142oby si\u0119 64 Ziemie. Pomimo swoich rozmiar\u00f3w obraca si\u0119 bardzo szybko. Dzie\u0144 na Uranie trwa zaledwie 17 godzin i 14 minut.<\/p>\n

Uran obraca si\u0119 jak b\u0105czek przewr\u00f3cony na bok. Oznacza to, \u017ce na biegunach S\u0142o\u0144ce znajduje si\u0119 czasami dok\u0142adnie nad g\u0142ow\u0105. Na ka\u017cdym z biegun\u00f3w lato i zima trwaj\u0105 po 21 lat, co sprawia, \u017ce s\u0105 to najgor\u0119tsze i najzimniejsze miejsca na naszej planecie!<\/p>\n

Kiedy sonda Voyager 2 zbli\u017cy\u0142a si\u0119 do Urana w 1986 roku, prawie nie wida\u0107 by\u0142o \u017cadnych chmur. Jednak najnowsze zdj\u0119cia wykonane przez Kosmiczny Teleskop Hubble\u2019a ujawni\u0142y kilka bardzo rozleg\u0142ych burz.<\/p>\n

G\u0142\u00f3wnymi gazami w jego g\u0119stej atmosferze s\u0105 wod\u00f3r i hel, a tak\u017ce niewielka ilo\u015b\u0107 metanu. (Metan rozprasza niebieskie \u015bwiat\u0142o, dlatego Uran wydaje si\u0119 niebieski). Jednak bardzo r\u00f3\u017cni si\u0119 on od Jowisza i Saturna.<\/p>\n

Uranus sk\u0142ada si\u0119 g\u0142\u00f3wnie z \u2018lod\u00f3w\u2019 \u2013 mieszanki wody, metanu i amoniaku. W jego centrum mo\u017ce znajdowa\u0107 si\u0119 niewielkie skaliste j\u0105dro. Oznacza to, \u017ce jak na swoje rozmiary jest bardzo lekki.<\/p>\n

Uran ma 27 znanych ksi\u0119\u017cyc\u00f3w. \u017baden z nich nie jest zbyt du\u017cy. Najwi\u0119kszymi ksi\u0119\u017cycami s\u0105 Oberon i Titania, kt\u00f3rych \u015brednica przekracza 1 500 km.<\/p>\n

Uran posiada r\u00f3wnie\u017c co najmniej tuzin ciemnych, zapylonych pier\u015bcieni. Wi\u0119kszo\u015b\u0107 z nich jest niezwykle cienka. Ich kszta\u0142t utrzymuj\u0105 pobliskie ksi\u0119\u017cyce \u201cpasterze\u201d. Co najmniej jeden pier\u015bcie\u0144 powsta\u0142 w wyniku zderze\u0144 meteoryt\u00f3w z ma\u0142ym satelit\u0105.<\/p>","protected":false},"excerpt":{"rendered":"
