I-ESA ilumkisa ukuba i-asteroid iya kudlula kufutshane noMhlaba nge-12 ka-Okthobha

ESA

Uninzi lwezixhobo ezinikezelwa ziiarhente ezahlukeneyo zelizwe jikelele kuphando lwendawo kunye nokuhlola. Ngaphakathi kwezi zinto zemali kunye nabasebenzi, kufuneka sigxininise ukuba kukho enye, ebaluleke kakhulu, enikezelwe kuphononongo lwendawo kunye nokuzama fumanisa kwaye ufumanise zonke iintlobo zosongelo kwiplanethi yethu ethandekayo uMhlaba kwangoko.

Ngenxa yoku, ayimangalisi into yokuba amaxesha ngamaxesha sifumana iingxelo ezisixelela ngendlela ezisondele kakhulu kuyo ii-asteroids, ngakumbi ezona zinkulu ezinokubangela ingozi eMhlabeni. Siza kuba nomzekelo ocacileyo olandelayo Nge-12 ka-Okthobha walo nyaka 2017, umhla apho, njengoko kuchaziwe ngu ESA, IArhente yezeNdawo yaseYurophu, asteroid 2012 TC4 iya kudlula kufutshane kakhulu noMhlaba.

I-asteroid eyi-15 ukuya kwi-30 yeemitha ububanzi iya kudlula kufutshane noMhlaba kodwa ngaphandle kokwenza naluphi na uhlobo lwesiphumo okanye ukungahambi kakuhle

Njengoko igama le-asteroid libonisa, ubukho bayo bufunyenwe kwi-2012 yi-Pan-STARRS panoramic survey telescope ebekwe eHawaii. Ngokubhekisele kwiimpawu zayo ezinomdla, phawula ukuba sithetha nge i-asteroid malunga ne-15 ukuya kwi-30 yeemitha ububanzi, ubungakanani obunokubonakala buncinci, ngakumbi xa sithelekisa nobukhulu obudlulileyo kufutshane noMhlaba kwaye obabumalunga neemitha ezingama-620 ububanzi, kodwa ukuba, ukuba ithe yahlasela iplanethi yethu, mhlawumbi ayinakubonakalisa kakubi, kodwa kunokubangela iingxaki ezithile ekufuneka sizicwangcisile kwaye ngaphezulu kwako konke ukulungele ukujongana nazo, yiyo yonke loo nto iintshukumo ezifanayo zikhona zibekwe esweni ngawo onke amaxesha.

Ngokwentetho ezenziwe ziingcali ezivela kwi-ESA uqobo kunye nenani elipheleleyo leenkwenkwezi ezijonge ukuhamba kwayo, kuqikelelwa ukuba i-asteroid 2012 TC4 iya kubhabha phezu kweplanethi yethu Isantya seekhilomitha ezili-14 ngomzuzwana ukuya ku umgama weekhilomitha ezingama-44.000. Ngokuqinisekileyo lo mgama uya kuthetha ukuba i-asteroid ayichaphazeli ukusebenza kweesathelayithi nakwezona ndawo zikude ukusuka kwi-geostationary orbit yoMhlaba kwaye zibekwe malunga ne-36.000 yeekhilomitha ukusuka eMhlabeni.

Ngo-2012 TC4

Ukuba i-asteroid efana ne-2012 TC4 ibinokuthi ibethe uMhlaba, ngekhe ibe neziphumo ezibi

Ngokwengxelo ezenziwe sisazinzulu UDetlef Koschny, Ilungu langoku leqela lophando lweeMpahla zoMhlaba, iqela elixhaswe ngqo ngemali ye-ESA:

Siyazi ngokuqinisekileyo ukuba akunakwenzeka ukuba le nto izakubetha eMhlabeni. Akukho bungozi.

Nangona kunjalo… Kuya kwenzeka ntoni ukuba, ngokuchasene nazo zonke iingxaki, i-asteroid ekugqibeleni iyitshintshe indlela eya kuyo kunye neentloko eziya eMhlabeni? Ngokucacileyo nangokutsho kweengcali ze-ESA eziye zabuzwa malunga noku kungenzeka, nangona kungenakulindeleka ukuba kubonakale, ifuthe lale asteroid kunye noMhlaba liza kuba semngciphekweni ofanayo nalowo wehlileyo eChelyabinsk, idolophu eseRussia, e Ngo-2013.

Njengesikhumbuzo, xelela ukuba sithetha ngeqhekeza lekomethi elaqhuma emoyeni. Umothuko ovelise olu dubulo lubangelwe Iifestile ezingaphezulu kwama-6.000 zezakhiwo ziya kwaphuka zibangele ukuba abantu abayi-1.500 benzakale. Njengoko ubona, icandelo elilungileyo loku kukuba asithethi ngomnyhadala oneziphumo ezibi okanye nantoni na enjalo, nangona kuya kufuneka sizilungiselele.

IPlanethi yomhlaba

Izazinzulu zethu ziya kuba nethuba lokuphanda ngokujikeleza kunye nokwenziwa kolu hlobo lomzimba wasezulwini

Ukushiya ecaleni into enokwenzeka yokuba into enje inokwenzeka, inyani kukuba oososayensi kwihlabathi liphela ngoku banethuba lokufunda ngakumbi malunga nokujikeleza kunye nokwenziwa kweeasteroids. Njengoko kunokufundwa kupapasho lweendaba olupapashwe ziingcali ze ESA:

Esi siganeko siza kusebenzisa uthungelwano lwamazwe aphesheya kwezokujonga kunye nemibutho yophando esebenza kukhuseleko lweplanethi.
