Be\u015finci Ay\u0131n Ke\u015ffi Tart\u0131\u015fmalar\u0131 Yeniden Ba\u015flat\u0131yor<\/h2>\n\n

Pl\u00fcton’un y\u00f6r\u00fcngesinde d\u00f6nen be\u015finci bir ay\u0131n ke\u015ffi, buzlu cismin yeniden gezegen olarak s\u0131n\u0131fland\u0131r\u0131l\u0131p s\u0131n\u0131fland\u0131r\u0131lmayaca\u011f\u0131na ili\u015fkin tart\u0131\u015fmalar\u0131 yeniden alevlendirdi. Pl\u00fcton, Uluslararas\u0131 Astronomi Birli\u011fi (IAU) taraf\u0131ndan 2006 y\u0131l\u0131nda c\u00fcce gezegen stat\u00fcs\u00fcne indirildi, ancak baz\u0131 bilim insanlar\u0131 yeni bulgunun yeniden de\u011ferlendirmeyi hakl\u0131 \u00e7\u0131kard\u0131\u011f\u0131na inan\u0131yor.<\/p>\n\n

IAU Gezegen Tan\u0131m\u0131<\/h2>\n\n

IAU’ya g\u00f6re bir gezegen \u00fc\u00e7 kriteri kar\u015f\u0131lamal\u0131d\u0131r:<\/p>\n\n

    \n
  1. G\u00fcne\u015f’in y\u00f6r\u00fcngesinde olmal\u0131d\u0131r.<\/li>\n
  2. Hidrostatik denge \u015feklini (neredeyse yuvarlak) alacak kadar yeterli k\u00fctleye sahip olmal\u0131d\u0131r.<\/li>\n
  3. Y\u00f6r\u00fcngesini di\u011fer nesnelerden temizlemi\u015f olmal\u0131d\u0131r.<\/li>\n<\/ol>\n\n

    Pl\u00fcton ilk iki kriteri kar\u015f\u0131l\u0131yor ancak \u00fc\u00e7\u00fcnc\u00fcs\u00fcn\u00fc kar\u015f\u0131lam\u0131yor. Y\u00f6r\u00fcngesi Nept\u00fcn’\u00fcn y\u00f6r\u00fcngesiyle kesi\u015fiyor ve yolunu di\u011fer nesnelerden temizlememi\u015f. Bu, IAU’nun Pl\u00fcton’u c\u00fcce gezegen olarak s\u0131n\u0131fland\u0131rmas\u0131na yol a\u00e7t\u0131; bu, asteroit olarak adland\u0131r\u0131lmak i\u00e7in \u00e7ok b\u00fcy\u00fck ancak gezegenler i\u00e7in gerekli t\u00fcm kriterleri kar\u015f\u0131lamayan bir nesne kategorisi.<\/p>\n\n

    Yeniden S\u0131n\u0131fland\u0131rma Arg\u00fcmanlar\u0131<\/h2>\n\n

    Baz\u0131 bilim insanlar\u0131, IAU’nun gezegen tan\u0131m\u0131n\u0131n \u00e7ok dar oldu\u011funu ve Pl\u00fcton’un yeniden gezegen olarak s\u0131n\u0131fland\u0131r\u0131lmas\u0131 gerekti\u011fini, \u00e7\u00fcnk\u00fc be\u015f ay\u0131 oldu\u011funu savunuyor. Aylar genellikle gezegensel stat\u00fcn\u00fcn bir i\u015fareti olarak kabul edilir, \u00e7\u00fcnk\u00fc nesnenin di\u011fer g\u00f6k cisimlerini \u00e7ekme ve tutma g\u00fcc\u00fcne sahip oldu\u011funu g\u00f6sterirler.<\/p>\n\n

    Ancak IAU, aylar\u0131n varl\u0131\u011f\u0131 veya yoklu\u011funun bir nesnenin gezegen olup olmad\u0131\u011f\u0131n\u0131 belirlemede bir fakt\u00f6r olmad\u0131\u011f\u0131n\u0131 belirtti. Odak noktas\u0131, nesnenin y\u00f6r\u00fcnge \u00f6zelliklerine ve y\u00f6r\u00fcngesini temizleme yetene\u011fine g\u00f6redir.<\/p>\n\n

    New Horizons G\u00f6revi \u0130\u00e7in Etkileri<\/h2>\n\n

    P5 olarak bilinen be\u015finci ay\u0131n ke\u015ffi, Temmuz 2015’te Pl\u00fcton ile bulu\u015fmas\u0131 planlanan New Horizons uzay arac\u0131 i\u00e7in \u00f6nemli etkilere sahip. Uzay arac\u0131n\u0131n, Pl\u00fcton’u \u00e7evreleyen bir enkaz alan\u0131nda gezinmesi gerekecek ve ek aylar\u0131n varl\u0131\u011f\u0131 bir tehlike olu\u015fturabilir.<\/p>\n\n

    Aylara \u0130sim Verme<\/h2>\n\n

    Pl\u00fcton’un be\u015finci ve d\u00f6rd\u00fcnc\u00fc aylar\u0131n\u0131n isimleri hen\u00fcz belirlenmedi, ancak muhtemelen Pl\u00fcton’un di\u011fer aylar\u0131, Charon, Hydra ve Nix i\u00e7in kullan\u0131lan Hades\/yeralt\u0131 d\u00fcnyas\u0131 temas\u0131n\u0131 izleyecekler.<\/p>\n\n

Be\u015finci ay\u0131n ke\u015ffi ate\u015fe benzin d\u00f6kt\u00fc, ancak IAU konuyu yak\u0131n zamanda yeniden de\u011ferlendirmeyi planlam\u0131yor. \u015eimdilik Pl\u00fcton bir c\u00fcce gezegen olarak kal\u0131yor, ancak gelecekte yeniden s\u0131n\u0131fland\u0131r\u0131lma ihtimali g\u00f6z ard\u0131 edilemez.<\/p>","protected":false},"excerpt":{"rendered":"
