Indalo iphela ayinasiphelo kwaye ihlala itshintsha. Iiplanethi azipheli kunye namandla azo. Umzekelo woku sisixa esingapheliyo seemeteorite eziwela kuthi, uninzi lwazo zincinci kangangokuba azibhaliswanga mntu. Kwaye ezinye ezininzi ezinokunika imiqondiso yolwazi olungenakucingelwa. Umzekelo ukuba eMhlabeni kukho into eya kuba sisiqwenga senye iplanethi.
Iqela lezazinzulu lamazwe ngamazwe limi ngelithi ilitye elinqabileyo elifumaneka kwintlango yeSahara eAlgeria, kuMntla Afrika liqhekeza leplanethi. Ngokukodwa, uphando lwabo luphawula ukuba kubonakala ngathi yintsalela ye- "iprotoplanet yakudala," ukwenza isibhakabhaka sibe nomdla ongaqhelekanga onokunika ulwazi olungazange lubonwe malunga neminyaka yokuqala yeSixokelelwano sethu seSolar. Ewe, akukho nto kwaye akukho nto incinci.
I-Erg Cheche 002 okanye i-EC 002 (njengegama le-meteorite) yafunyanwa ngoMeyi kulo nyaka uphelileyo kunye neziqwenga ezininzi zamatye ezinobunzima be-32 kilogram (70 pounds) kulwandle lwesanti yase-Erg Chech kumzantsi-ntshona weAlgeria.
Yachongwa ngokukhawuleza. Endaweni yokwakheka kokuba uninzi lweemeteorite ezifunyenweyo, ezenziwe xa iziqwenga zothuli kunye nelitye zinamathelana, ukuthungwa kwazo kwakungaqhubi, kufakwe iikristale zepyroxene (iminerali eyenziwe ngecalcium, imagnesium kunye nentsimbi). Yayiluhlaza bumnyama okanye imnyama, ine-vitreous sheen, efana namatye agqabhukileyo.
Oku kufunyaniswayo kubonisa ithuba elikhethekileyo lokufunda amanqanaba okuqala okubunjwa kweplanethi kwaye ufunde ngakumbi malunga neemeko kwimihla yokuqala yeSixokelelwano seSolar xa iiplanethi esizaziyo nesizithanda namhlanje zisaqulunqa.
Ngakumbi Malunga ne-EC 002
I-ScienceAlert inika ingxelo yokuba i-asteroid yakhawuleza yaxelwa njengengaqhelekanga emva kokufunyanwa kwayo kulwandle lwesanti ye-Erg Jonga ngoMeyi ka-2020 njengoko, ngokungafaniyo neemeteorite ezininzi, yayinziwe ngokucacileyo yintaba-mlilo, icebisa ukuba yaqala njengenxalenye yoqweqwe lweprotoplanet, eyathi yavela kwintaba-mlilo. yinto efana “nembumba” yesijikelezi-langa, emele inqanaba lokuqala lesigaba sokuzivelela kwayo.
Kodwa njengoko kuchazwe kwiphepha elitsha elipapashwe kwi-"Proceedings of the National Academy of Sciences," uhlalutyo lokubola kwe-radioactive ye-isotopes kwisampulu ibonisa ukuba yakha malunga ne-4,566 yezigidi zeminyaka eyadlulayo. Lixesha elide kunokuba uMhlaba ukhe wabakho, okuthetha ukuba mhlawumbi yinxalenye yehlabathi elahlukileyo, kwaye mhlawumbi ngoku lihambile.
Akucaci, ukuba yeyiphi iprotoplanet i-asteroid inokuba ivela kuyo. Nangona kunjalo, ekubeni ngoku lelona litye lidala le-magmatic elakhe lachongwa, abaphandi babhala kwiphepha labo, kuqinisekileyo ukuba iya kuba ngumxholo wohlalutyo olongezelelweyo. Yaye oko kufunyanwa zizazinzulu ngokufunda ngesi siqwenga samandulo kunokusikhanyisela ngembali yenkqubo yethu yeenkwenkwezi.
