Zingaphi iinkwenkwezi kwinkqubo solar? Xa namhlanje nje amanqaku, ukuthandwa social networking kunye nezinye iinxalenye Runet ngokufuthi uyakwazi ukufumana umbuzo ofanayo / nokuvota. Ngokuqhelekileyo, oko kukhatshwa izimvo malunga bakhaya abanengqondo obengaqondi ngokwesiseko ngaba isakhiwo kwikhaya lethu yesiqalo. Eneneni, kuhle ukuba zingaphi iinkwenkwezi kwinkqubo solar? Onjani umbuzo engevayo? Yiloo nto ke umsebenzi malunga iinkwenkwezi ezininzi ngayo kumnyele wethu, yaye oko bekuya kuba nzima ngakumbi, yaye oko kusengqiqweni ukubeka. Kodwa hayi yonke into elula kangaka! Wendele entliziyweni ngalo mbandela, unako ukuza zonke izinto ezimangalisayo ngokupheleleyo. Kubonakala ukuba phakathi abaphengululi mihla kakhulu umbuzo ngulo, njani iinkwenkwezi ezininzi kwinkqubo elanga. Ke umbuzo ngoku malunga abafuna yajika ezithandwayo kunye neengcamango pseudoscientific malunga nemvelaphi kwehlabathi, utyelelo ezingaqhelekanga okanye iyelenqe jikelele, kodwa ezisemajukujukwini kakhulu ohlonelwayo.
Kuiper Belt kunye Oort ilifu
Ukuba akunjalo bonke, ngoko ngokuqinisekileyo inkoliso yabemi eyaziwayo ukwakhiwa langa lethu langa: iiplanethi ezisentlabathini, wahlukana abaseleyo eli litye ibhanti isigebenga igesi Jupiter, singqongwe amakhonkco likaSaturn, i nguNeptune kude njalo njalo. abantu ngokuphawulekayo abambalwa, ukuba akukho umdla okhethekileyo kwesi sihloko, kuyaziwa ukuba bazisunduze iPluto ukusuka status emhlabeni. Inyaniso kukuba kwiminyaka emibini sewaka imizimba kwafunyanwa ngaphandle orbit, iPluto ayikho enasilela ubukhulu. Kuba ixesha lokuqala ukusukela kwimihla Greece yamandulo, lo mbuzo Wavuka phambi ngeenkwenkwezi: "Yaye, eneneni, ngokufanelekileyo ngokuba iplanethi?" Ngenxa Ngokwemvumelwano eyamkelekileyo ngokubanzi kunye nokwamkelwa eziliqela zokugweba, iPluto yakhethwa yiplanethi encinane, njengoko svezheotkrytye Eris, Sedna, kunye nabanye. Ezi zinto amehlo ezininzi kwaye evuliwe rhoqo of izazinzulu kunye nomzimba ngakumbi. ukuba bagxila ngamaxesha ezimbini akude iLanga ngaphezu komzila abanjengoNeptune, kwaye waziwa ngokuba Kuiper Belt. Noko ke, ukufunda ngakumbi uhlala lingena ezinomsila inkqubo solar waqiniseka ngeenkwenkwezi ukuba umthombo wabo - hayi Kuiper Belt. Ngokutsho concepts mihla, kusekho ngokuphindwe kaliwaka ngaphezulu, kumgama kunyaka ukukhanya omnye ngomnye disc ingqalelo okuqinileyo imizimba yasezulwini. Yaba inzondo yakhe kwaye bukhokelela abazali ngamaxesha kungena radius engaphakathi ezinomsila langa bombardment yokoqobo iiplanethi ezifana likaSaturn, iMars Earth. Kwakuyeyona izinto kwi Oort efini, kudala kwasekwa kufuphi iLanga, kodwa kamva saa nzulu emajukujukwini, kukujikeleza ngoku kwi komzila kude. Kodwa yintoni ebangela ukuphazamiseka ezi imizimba ebangela ukuba umane sibuyele kwelanga?
Nemesis
Kwaye apha umbuzo malunga iinkwenkwezi ezininzi njani iinzuzo kwinkqubo solar akaqhotyoshelwanga intlekisa, kodwa embi kakhulu. Ngeminyaka yee-80s yi paleontologists uJack Sepkoski noDavid Raup ubhengezwe ingcamango yokuba ubomi eMhlabeni efana kakhulu, yathotyelwa a ekutshabalaleni abaninzi kunye njalo umona - kule minyaka 26-30 eliwaka. Noko ke, izinto ezi ziphele nya, paleontologists azikwazanga ukufaka. Ngenxa yesi sizathu ukuba wazalwa ingcamango ngemvelaphi komhlaba ka - gxebe, emkhathini. Iqela izazinzulu ukuya kumhla zibonisa ukuba Sun unokuba inkwenkwezi-kabini, nto leyo, nenomlanga norhatyazo obomvu (kuba kusenjalo akukho namnye waqaphela), kwaye perturbs ilifu Oort ngamathuba axeliweyo, nto leyo ekhokelela ukuba bombardment cosmic boMhlaba ekutshabalaliseni bonke ubomi . nenomlanga ezingenzeka ebomvu ogama Nemesis. Kubulungisa kufanele kuqatshelwe ukuba Kwingcingane obomi nemesis le mihla ngakumbi elibuthathaka ngakumbi. Oku kunegalelo yokunqongophala impumelelo kwiphulo lakhe, kunye nokungaphumeleli ubungqina bombardment ngamaxesha athile, yaye ekugqibeleni ekungathembakalini malunga inguqulelo yale ukuphela rhoqo yezidalwa eziphilayo emhlabeni. Kwelinye icala, inkoliso iinkwenkwezi abadumile nje amaqabane. Umzekelo, yethu elikufutshane galactic ummelwane - inkqubo star kokubini lwe Alpha kunye Proxima Centauri. Nokuba bangaphi iminyaka iinkwenkwezi, njengoko ukujikeleza liziko eqhelekileyo womxhuzulane.
