Bu nedenle ara\u015ft\u0131rmac\u0131lar, bu gezegenlerin bir zamanlar kendi y\u0131ld\u0131zlar\u0131n\u0131n etraf\u0131nda olu\u015fup sonras\u0131nda daha a\u011f\u0131r di\u011fer kom\u015fular\u0131n\u0131n yer\u00e7ekiminin etkisiyle g\u00fcne\u015f sistemlerinden d\u0131\u015far\u0131 at\u0131lm\u0131\u015f olabilece\u011fini \u00f6ne s\u00fcr\u00fcyor.<\/p>\n
