A modern t\u00e1vcs\u00f6vek seg\u00edts\u00e9g\u00e9vel t\u00f6bb sz\u00e1z jeges \u00e9gitestet fedeztek fel a Neptunusz p\u00e1ly\u00e1ja t\u00fals\u00f3 oldal\u00e1n, a Kuiper-\u00f6v n\u00e9ven ismert r\u00e9gi\u00f3ban. Az \u00f6v nev\u00e9t Gerard Kuiperr\u0151l, a holland sz\u00e1rmaz\u00e1s\u00fa csillag\u00e1szr\u00f3l kapta, aki 1951-ben felvetette, hogy egyes \u00fcst\u00f6k\u00f6s\u00f6k ebb\u0151l a r\u00e9gi\u00f3b\u00f3l sz\u00e1rmazhatnak.<\/p>\n<\/div>\n

Az els\u0151 Kuiper-\u00f6v-objektumot 1992-ben fedezt\u00e9k fel, ami igazolta, hogy Kuiper elm\u00e9lete helyes volt. Felismer\u00e9s\u00fck neh\u00e9z, mivel nagyon halv\u00e1nyak \u00e9s rendk\u00edv\u00fcl lassan mozognak. Ezeknek az objektumoknak t\u00f6bb sz\u00e1z \u00e9vbe telik, mire egy teljes k\u00f6rt tesznek meg a Nap k\u00f6r\u00fcl.<\/p>\n

Ezek a testek val\u00f3sz\u00edn\u0171leg a bolyg\u00f3k kialakul\u00e1s\u00e1nak maradv\u00e1nyai. Az \u00f3ri\u00e1sbolyg\u00f3kkal val\u00f3 k\u00f6lcs\u00f6nhat\u00e1sok k\u00f6vetkezt\u00e9ben ker\u00fcltek ebbe a t\u00e1voli k\u00fcls\u0151 r\u00e9gi\u00f3ba.<\/p>\n

A legt\u00f6bb \u00e9gitest kicsi, \u00e1tm\u00e9r\u0151j\u00fck \u00e1ltal\u00e1ban 10\u201350 km. Eg\u00e9szen a k\u00f6zelm\u00faltig a Pl\u00fat\u00f3 volt a legnagyobb k\u00f6z\u00fcl\u00fck, b\u00e1r sz\u00e1mos m\u00e1s \u00e9gitest is szinte ugyanilyen nagy volt.<\/p>\n

Azt\u00e1n 2005-ben egy m\u00e9g nagyobb \u00e9gitestet fedeztek fel. A 2003 UB313 n\u00e9ven ismert \u00e9gitestet a tud\u00f3sok \u201cXena\u201d-nak bec\u00e9zt\u00e9k (a n\u00e9pszer\u0171 t\u00e9v\u00e9sorozat harcos hercegn\u0151je ut\u00e1n), am\u00edg meg nem kapt\u00e1k a hivatalos nev\u00e9t: Eris.<\/p>\n

Felfedez\u00e9sekor az Eris k\u00e9tszer olyan messze volt a Napt\u00f3l, mint a Pl\u00fat\u00f3 (97 Nap\u2013F\u00f6ld t\u00e1vols\u00e1g). Ezzel a Naprendszerben eddig felfedezett legmesszebb fekv\u0151 \u00e9gitest lett. P\u00e1ly\u00e1ja 44 fokos d\u0151l\u00e9ssz\u00f6ggel rendelkezik, \u00edgy a t\u00f6bbi bolyg\u00f3 p\u00e1ly\u00e1j\u00e1t\u00f3l j\u00f3val feljebb \u00e9s lejjebb halad. Kider\u00fclt tov\u00e1bb\u00e1, hogy van egy holdja, amelyet Dysnomia n\u00e9vre kereszteltek.<\/p>\n

Nem mindenki \u00e9rt egyet azzal, hogy a Pl\u00fat\u00f3t \u00e9s az Erist a Naprendszer kilencedik, illetve tizedik bolyg\u00f3j\u00e1nak kellene tekinteni. 2006-ban a Nemzetk\u00f6zi Csillag\u00e1szati Uni\u00f3 \u2018t\u00f6rpebolyg\u00f3knak\u2019 min\u0151s\u00edtette \u0151ket.<\/p>","protected":false},"excerpt":{"rendered":"
