D\u00fcnya, asteroitlere kar\u015f\u0131 savunmas\u0131z<\/b><\/p>\n

Yay\u0131nlanan rapora g\u00f6re NASA, \u00e7ok say\u0131da ABD devlet kurumunun kat\u0131ld\u0131\u011f\u0131 bir tatbikat ger\u00e7ekle\u015ftirdi.

Sonu\u00e7lar ise insanl\u0131k i\u00e7in iyiye i\u015faret etmiyor.<\/p>\n

Tatbikat kapsam\u0131nda asteroit boyutlar\u0131 60 ila 800 metre<\/strong> aras\u0131nda de\u011fi\u015firken, en olas\u0131 asteroit 100 ila 320 metre<\/strong> aras\u0131nda olacak.

D\u00fcnya\u2019ya gelen asteroitleri bile tespit edemiyoruz<\/b><\/p>\n

Haz\u0131rl\u0131ks\u0131z olunmas\u0131na ra\u011fmen baz\u0131 iyi haberler de var.

K\u00f6t\u00fc haber ise esas\u0131nda bu asteroitlerin \u00e7o\u011funun nereden gelebilece\u011fini bile bilmememiz. \u00d6rne\u011fin 2013\u2019te Rusya\u2019ya d\u00fc\u015fen<\/strong> 1.500 ki\u015finin yaralanmas\u0131na neden olan 20 metrelik asteroid de tespit edilememi\u015fti<\/strong>.

Bu cisim, D\u00fcnya\u2019y\u0131 ge\u00e7tikten 2 g\u00fcn sonra tespit <\/strong>edilebildi.
