Into ekucingelwa ukuba yi-asteroid engena kumjikelezo woMhlaba kwinyanga ezayo inokuba yinkunkuma epheleleyo. Ingcali ye-NASA ithi le nto inokuba yirokethi endala ukusuka kumzamo wokufika enyangeni ngo-1966, ngokwe-Associated Press .
Kwinyanga ephelileyo, into eyaziwa ngokuba yi-asteroid 2020 SO yayi ibonwe kwiteleskopu eMaui . Kwakulindelwe ukuba kungene umjikelo woMhlaba kule kwindla kwaye uqhubeke ujikeleze kude kube malunga noMeyi 2021, kwinto eyaziwa ngokuba yinyanga encinci, ngokwe Iphephancwadi iSmithsonian . CNN ixelwe ukuba isondele kufutshane ne-27,000 yeemayile kude.
Kodwa kwasekuqaleni, enye ithiyori yayikho phaya. Ndiyayikrokrela into esandula ukufunyanwa eyi-2020 SO ukuba ibe sisixhobo esidala esiyi-rocket ngoba ilandela umjikelezo malunga nelanga ofana kakhulu noMhlaba kunye neeapos, phantse isetyhula, kwindiza enye, kwaye kukude nje kancinci ukusuka elangeni. Kwindawo yayo ekude, uGqr Paul Chodas, umlawuli weZiko leNASA kunye neapos; yeZifundo eziPhantse zoMhlaba, uxelelwe CNN kwinyanga ephelile .

Ngoku ukuba iyasondela, kuya kuqala ukuba kube lula ukufumanisa ubunzima, kuqikelelwa ukuba malunga neenyawo ezingama-26, ingxelo ye-AP . Ngelixa zombini ii-asteroids kunye namarokethi amadala esithuba angabonakala njengamachaphaza ahamba esibhakabhakeni, uChodas uxelele inkonzo yeendaba ukuba indlela yokuziphatha iqhubeka nokukhomba kwingcinga yokuba iyitoti engaphezulu. I-Asteroids, wathi, izakuhamba ngee-angles ezingaqhelekanga, ngelixa le ishiyekile kwindiza yoMhlaba.
Ukwanayo nethiyori malunga neli rokethi lisenokuba lelo. Ndingaba ndiphosakele kule nto. Andifuni ukubonakala ndizithembile, uChodas uxelele i-AP, ecinga ukuba inokuba lelona nqanaba liphezulu le-rocket elonyusa uSurveyor 2 we-NASA ukuba aye enyangeni ngo-1966. iya kuba sengqiqweni into yokuba irokethi ivele ihlale idada nje, njengoko bekucwangcisiwe. Kokokuqala, ngokokubona kwam, ukuba zonke iziqwenga zidibane kunye nokwaziswa okwaziwayo, wongeze watsho.
Ngelixa ukuphosisa ii-asteroids zezinye izinto-kwaye ngokuchaseneyo-kuyinto eqhelekileyo, ezinye iingcali zibonakala ngathi ziyavumelana nembono kaChodas. UAlice Gorman weYunivesithi yase-Australia yeFlinders uxelelwe Isilumkiso seSayensi ukuba isantya naso asihambelani ne-asteroid: Isantya kubonakala ngathi sikhulu. Into endiyibonayo kukuba i & apos ihamba nje kancinci, ebonisa isantya sayo sokuqala. Oko & apos ngokuqinisekileyo sisipho esikhulu.
Kodwa ithemba lokuba ayiyiyo i-asteroid iyonwabisa nangakumbi kwiChodas. Ndonwabile ngale nto, yena uxelele iAP . Ibiyinto endiyithandayo ukufumana enye yezi kwaye ndizobe ikhonkco elinje, kwaye bendisenza amashumi eminyaka ngoku.
Nokuba kwenzeka ntoni, inye into eqinisekileyo: Akufuneki kubekho uloyiko malunga nokuqhubela eMhlabeni- ubuncinci hayi ngeli xesha, utshilo. Uqikelelo lwamva nje lweChodas kukuba luya kufakwa kumjikelo woMhlaba phakathi ku-Novemba emva koko lubuyele kumjikelo walo ngoMatshi.
