Uraan on P\u00e4ikesest seitsmes planeet. Selle avastas William Herschel 1781. aastal.<\/p>\n<\/div>\n

Uraan asub P\u00e4ikesest rohkem kui 2 800 miljonit km kaugusel. Sellel kaugusel on selle pilvede \u00fclemiste kihtide temperatuur -214 kraadi C. See liigub \u00fcsna aeglaselt ja peab l\u00e4bima pika tee, mist\u00f5ttu iga tiir kestab 84 aastat.<\/p>\n

Uraan on hiiglaslik planeet, meie P\u00e4ikeses\u00fcsteemi suuruselt kolmas planeet. Selle sisse mahuks 64 Maad. Oma suurusest hoolimata p\u00f6\u00f6rleb see kiiresti. P\u00e4ev Uraanil kestab vaid 17 tundi ja 14 minutit.<\/p>\n

Uraan p\u00f6\u00f6rleb nagu k\u00fcljele kukkunud vurr. See t\u00e4hendab, et poolustel on P\u00e4ike m\u00f5nikord otse pea kohal. M\u00f5lemal poolusel kestab suvi ja talv 21 aastat, mis teeb neist planeedi k\u00f5ige kuumemad ja k\u00f5ige k\u00fclmemad kohad!<\/p>\n

Kui kosmosesond \u201eVoyager 2\u201d k\u00fclastas 1986. aastal Uraani, polnud seal peaaegu \u00fchtegi pilve n\u00e4ha. Hubble\u2019i kosmoseteleskoobi hiljutised pildid on aga n\u00e4idanud m\u00f5ningaid v\u00e4ga suuri tormisid.<\/p>\n

Selle tiheda atmosf\u00e4\u00e4ri peamised gaasid on vesinik ja heelium, millele lisandub v\u00e4ike kogus metaani. (Metaan hajutab sinist valgust, mist\u00f5ttu Uraan paistab sinisena.) Siiski erineb see Jupiterist ja Saturnist m\u00e4rkimisv\u00e4\u00e4rselt.<\/p>\n

Uraan koosneb peamiselt \u2018j\u00e4\u00e4st\u2019 \u2013 vee, metaani ja ammoniaagi segust. Selle keskmes v\u00f5ib olla v\u00e4ike kivine tuum. See t\u00e4hendab, et oma suurusele on see planeet v\u00e4ga kerge.<\/p>\n

Uraanil on 27 teadaolevat kuud. \u00dckski neist ei ole eriti suur. Suurimad kuud on Oberon ja Titania, m\u00f5lema l\u00e4bim\u00f5\u00f5t on \u00fcle 1 500 km.<\/p>\n

Uraanil on ka v\u00e4hemalt tosin tumedat, tolmavat r\u00f5ngast. Enamik neist on \u00e4\u00e4rmiselt \u00f5hukesed. Nende kuju hoiavad paigas l\u00e4hedal asuvad \u201ckarjane\u201d-kuud. V\u00e4hemalt \u00fcks r\u00f5ngas on tekkinud meteoriitide kokkup\u00f5rke tagaj\u00e4rjel v\u00e4ikese kaaslasega.<\/p>","protected":false},"excerpt":{"rendered":"
