Isiqingatha se-asteroid ukuphakama kweMat. I-Everest kulindeleke ukuba idlule eMhlabeni kwinyanga ezayo.
Nangona i-asteroid- ibizwa 52768 (1998 OKUNYE2) - ayizukunxibelelana neplanethi yethu, inkulu ngokwaneleyo ukuba ukungqubana kuya kuba 'kukhulu ngokwaneleyo ukuba kubangele iziphumo zehlabathi,' I-NASA ithe xa kwafunyanwa okokuqala i-asteroid.
Kuyo yonke indawo ukusuka kwi-1.1 ukuya kwi-2.5 yeemayile ububanzi kwaye kuqikelelwe ukuba kudlule malunga ne-3.9 yezigidi zeemayile zoMhlaba ngo-Epreli 29, ukuhamba ngesantya esimalunga ne-19,460 yeekhilomitha ngeyure. I-flyby kulindeleke ukuba yenzeke ngo-4: 56 nge-ET ngo-Epreli 29.
I-asteroid ilandelelwa kuluhlu lwe-NASA lwezinto ezinokuba yingozi hayi ngenxa yokuba zinokubakho ukungqubana nomhlaba wethu kodwa ngenxa yobungakanani bayo kunye nenyaniso yokuba amaxesha ngamaxesha idlula ngoMhlaba. (Nangona loo ndawo idlulayo ingaphezulu kwamaxesha ali-15 umgama phakathi koMhlaba nenyanga.)

Ngokwedatha ye-NASA & apos; I-asteroid iqikelelwa ukuba idlule eMhlabeni amatyeli aliqela kwinkulungwane elandelayo, Eyona ndlela ikufutshane iya kuba ngo-Epreli 16, 2079, xa i-asteroid izakudlula malunga ne-929,560 yeekhilomitha ukusuka kwiplanethi (malunga namaxesha amathathu kuphela umgama phakathi koMhlaba nenyanga yawo ).
Nangona i-asteroid inkulu kakhulu, ayisiyiyo enkulu ukudubula uMhlaba odlulileyo kwimbali yakutshanje. Nge-1 kaSeptemba 2017, i-asteroid egama lingu-3122 uFlorence-okanye u-1981 ET3-wadlula. Kuqikelelwa ukuba ikho ukusuka kwi-2.5 ukuya kwi-5.5 yeemayile ububanzi ngoku ka CNN . Kwaye kuqikelelwa ukuba kwenziwe enye i-flyby ngo-Septemba 2, 2057.
Ezi flybys zijongwa ngu Iziko le-NASA leziFundo zeNto ezikufutshane noMhlaba . Balandela izinto ezikufutshane noMhlaba (ii-NEOs) ukumisela ubungakanani bazo, isantya kunye namathuba okungqubana nomhlaba. Iiarhente zasemajukujukwini ezinjengeNASA kunye neArhente YaseYurophu Yasemajukujukwini ineentlanganiso ezizayo ezicwangciselwe ukufunda okungakumbi ngeeasteroids. Okwangoku, i-NASA & apos; s I-OSIRIS-REx kunye neJapan & apos; s IHayabusa2 baphonononga indawo kwaye baya kubuyisa iisampulu ze-asteroid eMhlabeni kule minyaka izayo.
