Az Ur\u00e1nusz a Naphoz k\u00e9pest a hetedik bolyg\u00f3. William Herschel fedezte fel 1781-ben.<\/p>\n<\/div>\n

Az Ur\u00e1nusz t\u00f6bb mint 2 800 milli\u00f3 km-re fekszik a Napt\u00f3l. Ezen a t\u00e1vols\u00e1gon a felh\u0151takar\u00f3 tetej\u00e9nek h\u0151m\u00e9rs\u00e9klete -214 \u00b0C. Meglehet\u0151sen lassan mozog, \u00e9s hossz\u00fa utat kell megtennie, \u00edgy egy-egy kering\u00e9si ideje 84 \u00e9vig tart.<\/p>\n

Az Ur\u00e1nusz egy \u00f3ri\u00e1si \u00e9gitest, a Naprendszer\u00fcnk harmadik legnagyobb bolyg\u00f3ja. 64 F\u00f6ld f\u00e9rne el benne. M\u00e9ret\u00e9nek ellen\u00e9re rendk\u00edv\u00fcl gyorsan forog. Az Ur\u00e1nuszon egy nap mind\u00f6ssze 17 \u00f3ra 14 percig tart.<\/p>\n

Az Ur\u00e1nusz \u00fagy forog, mint egy oldal\u00e1ra d\u0151lt forg\u00f3csiga. Ez azt jelenti, hogy a Nap a sarkokn\u00e1l n\u00e9ha pontosan a fej\u00fcnk felett \u00e1ll. Mindk\u00e9t sarkon 21 \u00e9vig tart\u00f3 ny\u00e1r \u00e9s t\u00e9l van, \u00edgy ezek a bolyg\u00f3 legmelegebb \u00e9s leghidegebb helyei!<\/p>\n

Amikor a Voyager 2 \u0171rsonda 1986-ban elhaladt az Ur\u00e1nusz mellett, alig l\u00e1tszott felh\u0151. A Hubble-\u0171rt\u00e1vcs\u0151 leg\u00fajabb felv\u00e9telei azonban n\u00e9h\u00e1ny nagyon nagy vihart mutattak.<\/p>\n

S\u0171r\u0171 l\u00e9gk\u00f6r\u00e9nek f\u0151 g\u00e1zai a hidrog\u00e9n \u00e9s a h\u00e9lium, kis mennyis\u00e9g\u0171 met\u00e1nnal. (A met\u00e1n sz\u00e9tsz\u00f3rja a k\u00e9k f\u00e9nyt, ez\u00e9rt t\u0171nik az Ur\u00e1nusz k\u00e9knek.) Ugyanakkor nagyon k\u00fcl\u00f6nb\u00f6zik a Jupitert\u0151l \u00e9s a Szaturnust\u00f3l.<\/p>\n

Az Ur\u00e1nusz f\u0151k\u00e9nt \u2018j\u00e9gb\u0151l\u2019 \u00e1ll \u2013 v\u00edz, met\u00e1n \u00e9s amm\u00f3nia kever\u00e9k\u00e9b\u0151l. K\u00f6z\u00e9ppontj\u00e1ban val\u00f3sz\u00edn\u0171leg egy kis szikl\u00e1s mag tal\u00e1lhat\u00f3. Ez azt jelenti, hogy m\u00e9ret\u00e9hez k\u00e9pest nagyon k\u00f6nny\u0171.<\/p>\n

Az Ur\u00e1nusznak 27 ismert holdja van. Ezek k\u00f6z\u00fcl egyik sem t\u00fal nagy. A legnagyobb holdak az Oberon \u00e9s a Titania, amelyek \u00e1tm\u00e9r\u0151je mindkett\u0151n\u00e9l meghaladja az 1 500 km-t.<\/p>\n

Az Ur\u00e1nusznak legal\u00e1bb egy tucat s\u00f6t\u00e9t, poros gy\u0171r\u0171je is van. Ezek t\u00f6bbs\u00e9ge rendk\u00edv\u00fcl v\u00e9kony. Alakjukat a k\u00f6zelben kering\u0151 \u201cp\u00e1sztorholdak\u201d tartj\u00e1k fenn. Legal\u00e1bb egy gy\u0171r\u0171 egy kis holdba becsap\u00f3d\u00f3 meteoritok hat\u00e1s\u00e1ra j\u00f6tt l\u00e9tre.<\/p>","protected":false},"excerpt":{"rendered":"
