Sodobni teleskopi so odkrili na stotine ledenih teles onstran Neptunove orbite, v obmo\u010dju, znanem kot Kuiperjev pas. Pas je poimenovan po Gerardu Kuiperju, astronomu nizozemskega rodu, ki je leta 1951 predlagal, da nekateri kometi morda izvirajo iz tega obmo\u010dja.<\/p>\n<\/div>\n

Prvo telo iz Kuiperjevega pasu je bilo odkrito leta 1992, kar je potrdilo pravilnost Kuiperjeve teorije. Njihovo odkrivanje je te\u017eko, saj so zelo slabo vidna in se gibljejo zelo po\u010dasi. Ta telesa potrebujejo ve\u010d sto let, da opravijo en obhod okoli Sonca.<\/p>\n

Ti objekti so verjetno ostanki iz \u010dasa nastanka planetov. V to oddaljeno zunanjo regijo so jih izstrelile interakcije z velikimi planeti.<\/p>\n

Ve\u010dina teles je majhnih, obi\u010dajno imajo premer od 10 do 50 km. \u0160e nedavno je bil Pluton najve\u010dji \u010dlan te skupine, \u010deprav je bilo kar nekaj drugih teles skoraj enako velikih.<\/p>\n

Leta 2005 so nato odkrili \u0161e ve\u010dji objekt. Znani pod oznako 2003 UB313 so mu znanstveniki nadeli vzdevek \u201cXena\u201d (po bojeviti princesi iz priljubljene televizijske serije), dokler mu niso dodelili uradnega imena Eris.<\/p>\n

Ob odkritju je bila Eris od Sonca dvakrat dlje kot Pluton (97 razdalj med Soncem in Zemljo). S tem je postala najbolj oddaljeno telo, ki je bilo doslej opazovano v Oson\u010dju. Njena tirnica je poleg tega nagnjena za 44 stopinj, zato se giblje precej nad in pod tirnicami drugih planetov. Ugotovljeno je bilo tudi, da ima luno, imenovano Dysnomia.<\/p>\n

Ni vsi se strinjajo, da bi bilo treba Pluton in Eris obravnavati kot deveti in deseti planet v Oson\u010dju. Leta 2006 ju je Mednarodna astronomska zveza uvrstila med \u2018pritlikave planete\u2019.<\/p>","protected":false},"excerpt":{"rendered":"
