Inqwelomoya ibhabha kwiimayile ezingama-575 ngeyure, ekhawulezayo ngokukhawuleza. ISitishi saMazwe ngaMazwe sisebenza ngokubhabha ngeemayile ezili-17, 100 ngeyure, esikhawulezayo kakhulu. Kwaye i-asteroid 2001 FO32 imalunga nokubhabha uMhlaba odlulileyo kwii-76,980 zeekhilomitha ngeyure, eyiyo ngokungacingekiyo ngokukhawuleza. Sithetha kaninzi ngesantya sesandi.
I-asteroid inokuba yeyona nto inkulu kwaye ikhawulezayo ukusondeza umhlaba-kulo nyaka, isenza njalo ngoMatshi 23 ngo-16: 03 e-UTC (ngo-11: 03 ekuseni nge-EST). Izazinzulu ziqikelela ukuba iphakathi kwesiqingatha sekhilomitha kunye nemayile enye ubukhulu, iyenza ukuba ibe nkulu kune-97% yolunye ulwazi iiasteroids .
Ngelixa i-2001 FO32 ichongwe njenge-asteroid 'enokuba yingozi' yi-NASA, ii-apos azizukungqubana noMhlaba ngeli xesha lokujikeleza (okanye kwiipasi ezintlanu ezizayo, eziza kwenzeka rhoqo kwiminyaka emithathu ukuya kwemihlanu). Ngeli xesha lokubhabha, iya kuba malunga ne-1.3 yezigidi zeemayile ukusuka kwiplanethi yethu, okanye malunga namaxesha amahlanu ukuya enyangeni. Ngokuthelekisa, eyona asteroid ikufutshane I-apos eyakhe yatyikitywa uMhlaba odlulileyo- okanye ubuncinci eyona ikufutshane esikubonileyo- yenze njalo kumphakamo wee-1,830 zeekhilomitha, ngo-Agasti 2020. Leyo yayincinci - iphakathi kwe-10 ne-20 iinyawo ububanzi.
Umfanekiso we-NASA we-asteroid Ityala: NASA
Kuba awufanelanga ukuba nexhala malunga nale asteroid isusa ubomi eMhlabeni, ungahlala phantsi, uphumle, kwaye wonwabele umboniso njengoko ulimaza umhlaba esihlala kuwo. Ngenxa yobungakanani bayo kunye nesantya, sinokwazi ukubona intshukumo ye-asteroid & apos esibhakabhakeni ngexesha lokwenyani- okoko nje sijongayo ngeteleskopu. Uninzi lwee-asteroids zincinci kwaye ziyacotha, oko kuthetha ukuba zibonakala zimile, njengenkwenkwezi okanye iplanethi, xa uzijonga ngelensi. Kodwa ngamehlo ethu (encediswa yiteleskopu), ngo-2001 i-FO32 inokubonakala ngathi yinguqulelo ecothayo yenqwelomoya ekuphakameni ngenqanawa okanye kwiSitishi saMazwe ngaMazwe esijikelezayo.
Unomdla wokwazi ukuba yintoni enye esithubeni enokusikhokelela kungekudala? IZiko le-NASA kunye neapos; yeZifundo eziPhantse zaMhlaba (i-CNEOS) igcina uluhlu lwazo zonke ii-NEOs ezaziwayo oko kuyakwenza ukusondela kufutshane kungekudala. Ewe asiyifumananga konke iiasteroids phandlapha, ngoko ngekhe wazi ukuba zeziphi & iiapos ezihleli ekoneni.
