Uranus er den syvende planet regnet fra Solen. Den blev opdaget af William Herschel i 1781.<\/p>\n<\/div>\n

Uranus ligger mere end 2.800 millioner km fra Solen. P\u00e5 denne afstand er temperaturen i skytoppene -214 grader C. Den bev\u00e6ger sig ret langsomt og har en lang vej at tilbagel\u00e6gge, s\u00e5 hver oml\u00f8bsperiode varer 84 \u00e5r.<\/p>\n

Uranus er en k\u00e6mpe planet, den tredjest\u00f8rste planet i vores solsystem. Der ville v\u00e6re plads til 64 jordkloder indeni den. P\u00e5 trods af sin st\u00f8rrelse roterer den meget hurtigt. En dag p\u00e5 Uranus varer kun 17 timer og 14 minutter.<\/p>\n

Uranus drejer rundt som en snurretop, der er v\u00e6ltet p\u00e5 siden. Det betyder, at Solen nogle gange st\u00e5r lige over hovedet ved polerne. Hver pol har en sommer og en vinter, der varer 21 \u00e5r, hvilket g\u00f8r dem til de varmeste og koldeste steder p\u00e5 planeten!<\/p>\n

Da rumfart\u00f8jet Voyager 2 passerede Uranus i 1986, var der n\u00e6sten ingen skyer at se. Nylige billeder fra Hubble-rumteleskopet har imidlertid afsl\u00f8ret nogle meget store storme.<\/p>\n

De vigtigste gasser i dens t\u00e6tte atmosf\u00e6re er brint og helium, med en lille m\u00e6ngde metan. (Metanet spreder bl\u00e5t lys, hvilket er grunden til, at Uranus ser bl\u00e5 ud). Den adskiller sig dog meget fra Jupiter og Saturn.<\/p>\n

Uranus best\u00e5r hovedsageligt af \u2018is\u2019 \u2013 en blanding af vand, metan og ammoniak. I dens centrum findes der muligvis en lille stenkerne. Det betyder, at den er meget let i forhold til sin st\u00f8rrelse.<\/p>\n

Uranus har 27 kendte m\u00e5ner. Ingen af dem er s\u00e6rlig store. De st\u00f8rste m\u00e5ner er Oberon og Titania, som begge har en diameter p\u00e5 over 1.500 km.<\/p>\n

Uranus har desuden mindst et dusin m\u00f8rke, st\u00f8vede ringe. De fleste af disse er ekstremt tynde. De holdes i form af n\u00e6rliggende \u201chyrdem\u00e5ner\u201d. Mindst \u00e9n ring er dannet ved, at meteoritter er styrtet ned i en lille m\u00e5ne.<\/p>","protected":false},"excerpt":{"rendered":"
