Uran je sedmi planet od Sonca. Odkril ga je William Herschel leta 1781.<\/p>\n<\/div>\n

Uran le\u017ei ve\u010d kot 2.800 milijonov km od Sonca. Na tej razdalji je temperatura vrha njegovih oblakov -214 stopinj Celzija. Giblje se precej po\u010dasi in mora prehoditi dolgo pot, zato vsak obhod traja 84 let.<\/p>\n

Uran je orja\u0161ki svet, tretji najve\u010dji planet v na\u0161em Oson\u010dju. Vanj bi se zmestilo 64 Zemlj. Kljub svoji velikosti se hitro vrti. Dan na Uranu traja le 17 ur in 14 minut.<\/p>\n

Uran se vrti kot vrte\u010dka, ki je padla na bok. To pomeni, da je Sonce na polih v\u010dasih neposredno nad glavo. Na vsakem polu traja poletje in zima po 21 let, zaradi \u010desar sta to najbolj vro\u010da in najhladnej\u0161a mesta na planetu!<\/p>\n

Ko je vesoljska sonda Voyager 2 leta 1986 obiskala Uran, ni bilo videti skoraj nobenih oblakov. Nedavne slike, posnete s Hubblovim vesoljskim teleskopom, pa so pokazale nekaj zelo velikih neviht.<\/p>\n

Glavni plini v njegovi gosti atmosferi sta vodik in helij, z majhno koli\u010dino metana. (Metan razpr\u0161uje modro svetlobo, zato se Uran zdi modro). Vendar se zelo razlikuje od Jupitra in Saturna.<\/p>\n

Uran je v glavnem sestavljen iz \u2018ledov\u2019 \u2013 me\u0161anice vode, metana in amoniaka. V njegovem sredi\u0161\u010du je morda majhno kamnito jedro. To pomeni, da je glede na svojo velikost zelo lahek.<\/p>\n

Uran ima 27 znanih lun. Nobena od njih ni posebej velika. Najve\u010dji sateliti sta Oberon in Titania, ki imata oba premer ve\u010d kot 1.500 km.<\/p>\n

Uran ima tudi vsaj ducat temnih, pra\u0161nih obro\u010dev. Ve\u010dina med njimi je izredno tanka. Njihovo obliko ohranjajo bli\u017enji \u201cpastirski\u201d luni. Vsaj en obro\u010d je nastal zaradi trkov meteoritov z majhnim satelitom.<\/p>","protected":false},"excerpt":{"rendered":"
