Ngo-Meyi-200, kumhlaba wentlango yeSahara, iMeteorite enganqabileyo yafunyanwa, eyesiqwengana esasingenaxesha lokwenza iplanethi. Kukholelwa ukuba ilitye elincinci lasekwa ngaphezulu kwe-4.6 yezigidigidi kwiminyaka eyadlulayo, oko kukuthi, mdala kunomhlaba. Abaphandi basaqhubeka nokufunda into efunyenweyo kwaye bakholelwe ukuba inokutyhila iinyani ezininzi ezinomdla malunga nokwenziwa kweeplanethi kwiSolar System. Njengenxalenye yeli nqaku, ndicebisa ukuba ndifumanise ukuba leliphi ngqo izazinzulu ezibuqondayo ngengqondo engaqhelekanga kwaye kutheni le nto injalo, kwaye ayikwazanga ukwenzakaliswa. Kufanelekile ukuqala kwento yokuba into efunyenweyo ayikhiwanga kumasuntsu achumileyo wothuli kunye namatye, njengamateriorites aqhelekileyo. Imeteorite inemvelaphi yentaba-mlilo, oko kukuthi, ibhekisa kwiklasi yama-Ahondries, malunga neziganeko endizikhankanyayo.
I-meteorite kwiNtlango yeSahara
Ngokutsho kohlelo lwesayensi yesayensi, i-meteorite yanikwa igama elithi i-Erg Cheng 002 (EC 002). Yafunyanwa kwikhilogramu enkulu yesiqwengana sobuzwe, kumhlaba wentlabathi yesanti ye-erg-chech entshona yeSahara. Izazinzulu zazikhawuleza zayiqonda ukuba zijongana nento engaqhelekanga kwaye inqabile kakhulu. Ngokwesiqhelo, obizwa ngokuba zii-meterites ezinolwazi lokuzila ziwela emhlabeni, eziqukethe i-choreev ye-choreev-yefomu yefomu ye-sperical kunye ne-Derical Plamer ene-millimeter engaphezulu kwe-1 millimitha. Kwaye iMeterite yafumana iMeteleOrite ibhekisa kwi-Ahondrita, enesifo se-chondrov. Kukholelwa ukuba oo-Ahondririririririririt bahlukile kwiindlela ezijikelezayo ngenxa yokunyibilika, ezihlala zenzeka kwiinkqubo zentaba-mlilo.
Izazinzulu zikholelwa ukuba i-meteorite yinxalenye yeeproplaokhi. Eli ligama leplanethi kumanqanaba okuqala okwenzeka, esele iphumelele kwinqanaba lokunyibilika. Oku kungqinwa yiminyaka yeMeteorite-Uhlalutyo lwabonisa ukuba lwenziwa malunga ne-4.6 yezigidigidi kwiminyaka eyadlulayo. Ukuthelekisa, iminyaka yomhlaba kuqikelelwa kwiminyaka eyi-4.5 yezigidigidi. Oko kukuthi, iMeteorite ivele kancinci kuneplanethi yethu kwaye, ngokufanelekileyo, phezu kwayo. Kwiibhiliyoni zeminyaka, wabhabha kwimigca yeSolar Systory kude kube sekupheleni, akazange awe kwintsimi yeSahara.
Ngokutsho kwabaphandi, ukufunyanwa kweMeterite yinto enqabileyo kwaye ebaluleke kakhulu kuluntu lwezenzululwazi. Kwaye ngokubanzi, ithuba lokufumanisa ukuba i-Ahondrite evela kwinzululwazi incinci kakhulu. Ngokwe-datha ye-teritin ye-bulletin, apho idatha evela kuzo zonke iilensi iwela emhlabeni, kuyo yonke imbali yokuqaphela, abaphandi bafumene kuphela ama-3,179 kuphela ama-teteorites kuphela. Eminye imithombo ithi ii-ahondriris ziintlobo zeziqhelo zeMeteorites, kodwa i-snug kukuba ayinakwenzeka ukuba ifumane rhoqo njengoko ndingathanda.

Iproplanethi ye-proplanet
Ngokuphathelele ukuba kutheni i-proplatine yayingazalwanga, izazinzulu zinethiyori enye. Ulula kwaye uthi into yasezulwini yatshatyalaliswa, yajika yaba luthuli. Kusenokwenzeka ukuba iproplanet iba yinxalenye yento enkulu. Iiprojetho ze-BUK zinokubandakanya izinto ezibizwa njengo-Adesit. Ihlulelwe ngumxholo wenani elikhulu le-silica kunye nezazinzulu zikholelwa ukuba ngoku ukufumana imigaqo-nkqubo evela kwizinto ezinjalo inzima kakhulu. Kwaye konke kuba uninzi lwayonyamalala, kwaye ngaphandle kokukhulu kakhulu.
Ngokubanzi, iiprofatiki ziphakathi kwezinto ezingaqondakaliyo. Ngo-2016, abaphandi babeka phambili inkangeleko enesibindi sokuba enye yeeproplatwats zidibene nenyanga. Inyani yile yokuba kwi-satellite yeplanethi yethu kukho i-crater enkulu kakhulu, eyaziwa njengolwandle lweemvula. Ububanzi bayo bulingana neekhilomitha ezili-1123, ke butyhilekile emhlabeni. Ixesha elide, izazinzulu zaziqinisekile ukuba le crater ivele ngenxa yokungqubana kwemeteorite. Kodwa izazinzulu zaseMelika aziyi kubandakanyi ukuba kube kanye ixesha elide kunye nesatellite, into efana nepropanethi yenzeka. Unokufunda ngakumbi ngale thengo kule nto.
Ukuba ufuna ukwazi ngakumbi malunga ne-meteorites, ndicebisa ukuba ndenze le khonkco kwaye ndifunde ngabo bonke ababaluleke kakhulu. Kwinqaku, ndixelele ukuba zeziphi iintlobo ze-meteorites zahlulwa, apho zinokufumaneka khona kwaye zize zithengise. Ndiye ndachukumisa umxholo we meterites yobuxoki kunye nokuntywila kwabo. Ngokubanzi, yajika ineenkcukacha kakhulu, ke ngokufunda okumnandi!
