Emva kweCorona, iasteroid enkulu ingqubana noMhlaba kwaye isoyikise ubomi kuwo

Amajelo eendaba kunye neendawo zokunxibelelana kwezentlalo zazigcwele iindaba zokuba i-asteroid enkulu inokungqubana noMhlaba kwinyanga ezayo, iyitshabalalise ngokupheleleyo kwaye iphelise impucuko yabantu. intsholongwane Inoveli Corona.

Iphephandaba laseBrithani, "Express", libike kwiwebhusayithi yalo, ukuba "i-NASA" yalumkisa nge-asteroid enkulu esondela kuMhlaba ngo-Aprili ozayo, kwaye kuya kuba kwanele ukuphelisa impucuko yabantu ukuba ingqubuzana noMhlaba.

Kwaye ingxelo epapashwe liphephandaba yathi izazi ngeenkwenkwezi zibonise ukuba ngoku zilandelela indlela ye-asteroid ebizwa ngokuthi "1998 OR2" kwaye yaziwa ngokuba yinombolo "52768", ngeZiko le-Near-Earth Object Studies "CNEOS" eCalifornia, I-USA.

Ubungakanani be-asteroid buqikelelwa malunga neekhilomitha ezi-2.5 okanye iikhilomitha ezi-4.1 - ngokwemilinganiselo ye-NASA yobukhulu be-asteroid - kwaye iya eMhlabeni ngesantya se-8.7 ​​km ngesekhondi okanye i-19461 yeekhilomitha ngeyure, kunye nayo nayiphi na into yendawo. obo bukhulu kunye nokuhamba ngesantya eso kunokutshabalalisa iplanethi ngokupheleleyo, kwaye kulindeleke ukuba iya kungqubana noMhlaba nge-29 ka-Epreli.

Izazi ngeenkwenkwezi ziqikelela ukuba izinto zasemajukujukwini ezilolo hlobo, impembelelo yazo inako ukubangela ukutshatyalaliswa kwehlabathi, kwaye enye kuma-50 inethuba lokungqubana noMhlaba rhoqo emva kweminyaka eyi-100.

Ngokutsho kwePlanetary Society, iasteroid engaphezu kwe-0.6 yeekhilomitha (1 km) ububanzi inkulu ngokwaneleyo ukuba ingasongela intshabalalo yehlabathi.

UGqr Bruce Bates, we-International Group of Astronomers, waqinisekisa ukuba ii-asteroids ezincinci zingqubana ngokuphindaphindiweyo noMhlaba, kodwa zivutha emoyeni ngaphandle komonakalo omkhulu, kodwa ubukhulu bale asteroid bubonisa intlekele.
