Uranus \u00e4r den sjunde planeten r\u00e4knat fr\u00e5n solen. Den uppt\u00e4cktes av William Herschel \u00e5r 1781.<\/p>\n<\/div>\n

Uranus ligger mer \u00e4n 2 800 miljoner km fr\u00e5n Solen. P\u00e5 detta avst\u00e5nd \u00e4r temperaturen vid molntopparna -214 grader Celsius. Planeten r\u00f6r sig ganska l\u00e5ngsamt och har en l\u00e5ng v\u00e4g att tillryggal\u00e4gga, s\u00e5 varje omloppsbana tar 84 \u00e5r.<\/p>\n

Uranus \u00e4r en j\u00e4ttelik planet, den tredje st\u00f6rsta i v\u00e5rt solsystem. 64 jordklot skulle f\u00e5 plats inuti den. Trots sin storlek roterar den snabbt. En dag p\u00e5 Uranus varar bara 17 timmar och 14 minuter.<\/p>\n

Uranus snurrar som en snurra som har v\u00e4lts p\u00e5 sidan. Det inneb\u00e4r att solen ibland st\u00e5r rakt \u00f6ver polerna. Vid varje pol r\u00e5der en sommar och en vinter som varar i 21 \u00e5r, vilket g\u00f6r dem till de hetaste och kallaste platserna p\u00e5 planeten!<\/p>\n

N\u00e4r rymdsonden Voyager 2 passerade Uranus 1986 syntes knappt n\u00e5gra moln alls. Nya bilder fr\u00e5n Hubble-teleskopet har dock visat att det f\u00f6rekommer n\u00e5gra mycket stora stormar.<\/p>\n

De viktigaste gaserna i dess t\u00e4ta atmosf\u00e4r \u00e4r v\u00e4te och helium, tillsammans med en liten m\u00e4ngd metan. (Metanet sprider bl\u00e5tt ljus, vilket \u00e4r anledningen till att Uranus ser bl\u00e5 ut.) Den skiljer sig dock mycket fr\u00e5n Jupiter och Saturnus.<\/p>\n

Uranus best\u00e5r huvudsakligen av \u2018is\u2019 \u2013 en blandning av vatten, metan och ammoniak. I dess centrum kan det finnas en liten stenig k\u00e4rna. Det inneb\u00e4r att planeten \u00e4r mycket l\u00e4tt i f\u00f6rh\u00e5llande till sin storlek.<\/p>\n

Uranus har 27 k\u00e4nda m\u00e5nar. Ingen av dem \u00e4r s\u00e4rskilt stor. De st\u00f6rsta m\u00e5narna \u00e4r Oberon och Titania, som b\u00e5da har en diameter p\u00e5 \u00f6ver 1 500 km.<\/p>\n

Uranus har dessutom minst ett dussin m\u00f6rka, dammiga ringar. De flesta av dessa \u00e4r extremt tunna. De h\u00e5lls i form av n\u00e4rliggande \u201cherdem\u00e5nar\u201d. Minst en ring bildas n\u00e4r meteoriter kraschar in i en liten m\u00e5ne.<\/p>","protected":false},"excerpt":{"rendered":"
