Kaasaegsed teleskoobid on avastanud sadu j\u00e4iseid taevakehi Neptuuni orbiidist kaugemal, piirkonnas, mida tuntakse Kuiperi v\u00f6\u00f6na. V\u00f6\u00f6 on saanud nime Gerard Kuiperi j\u00e4rgi, Hollandi p\u00e4ritolu astronoomi, kes pakkus 1951. aastal v\u00e4lja, et m\u00f5ned komeedid v\u00f5ivad p\u00e4rineda just sellest piirkonnast.<\/p>\n<\/div>\n

Esimene Kuiperi v\u00f6\u00f6 objekt avastati 1992. aastal, mis t\u00f5estas, et Kuiperi teooria oli \u00f5ige. Nende avastamine on keeruline, kuna need on v\u00e4ga n\u00f5rgalt paistvad ja liiguvad v\u00e4ga aeglaselt. Nendel objektidel kulub sadu aastaid, et teha \u00fcks tiir \u00fcmber P\u00e4ikese.<\/p>\n

Need objektid on t\u00f5en\u00e4oliselt planeetide tekkimise j\u00e4\u00e4gid. Need paisati hiidplaneetidega toimunud vastastikm\u00f5jude tagaj\u00e4rjel sellesse kaugesse v\u00e4limisse piirkonda.<\/p>\n

Enamik objekte on v\u00e4ikesed, l\u00e4bim\u00f5\u00f5duga tavaliselt 10\u201350 km. Veel hiljuti oli Pluuto selle r\u00fchma suurim liige, kuigi mitmed teised objektid olid peaaegu sama suured.<\/p>\n

\"Eris\"

Siis, 2005. aastal, leiti veelgi suurem objekt. See, mida tuntakse nimetusega 2003 UB313, sai teadlastelt h\u00fc\u00fcdnime \u201cXena\u201d (populaarse telesarja s\u00f5dalasprintsessi j\u00e4rgi), kuni talle anti ametlik nimi \u2013 Eris.<\/p>\n

Avastamise ajal asus Eris P\u00e4ikesest kaks korda kaugemal kui Pluuto (97 P\u00e4ikese-Maa vahekaugust). See tegi temast seni P\u00e4ikeses\u00fcsteemis avastatud k\u00f5ige kaugemal asuva objekti. Tema orbiit on kaldu 44 kraadi v\u00f5rra, mist\u00f5ttu liigub ta teistest planeetidest m\u00e4rkimisv\u00e4\u00e4rselt k\u00f5rgemal ja madalamal. Samuti on avastatud, et tal on kuu nimega Dysnomia.<\/p>\n

Mitte k\u00f5ik ei ole n\u00f5us, et Pluutot ja Erist tuleks pidada P\u00e4ikeses\u00fcsteemi \u00fcheksandaks ja k\u00fcmnendaks planeediks. 2006. aastal liigitas Rahvusvaheline Astronoomia Liit need \u2018k\u00e4\u00e4busplaneetideks\u2019.<\/p>","protected":false},"excerpt":{"rendered":"
