Los iimeteoroids zizinto ezincinci ezingaphakathi kwisixokelelwano sezijikelezi-langa kwaye ezinomlinganiselo, phakathi kwe-0,1mm ukuya kwi-50m ububanzi, ubukhulu. Umda ophezulu ngokubhekiselele kubukhulu buchaphazelekayo, yi-50m. Lo bukhulu obusetyenziselwa ukukwazi ukuhlula kwii-comets kunye ne-asteroids. Kwelinye icala, umda wesayizi osezantsi yi-100 µm. Ngale ndlela yahlukile kuthuli lwecosmic.
Nangona kunjalo, imida yobungakanani ayidli ngokusetyenziswa ngokungqongqo kakhulu. Kuba ayicacanga ukutyunjwa kwezinto ezikufutshane kule mida. Enyanisweni, eyona nkcazo isetyenziswa kakhulu yileyo ithi i-meteoroid ngumzimba wesibhakabhaka phakathi kwe-0,1mm kunye ne-50m. Oku kukhankanywe ngasentla, ngokwenene kuphuma kwinkcazo yeRoyal Astronomical Society.
Le nkcazelo ikwadityaniswe naleyo ye-meteoroid ekufutshane-noMhlaba, ethe yadluliselwa kwimeteoroids nayo engekho kufutshane noMhlaba. Inkcazo iya kuba yinto enezinto ezijikelezayo kwindawo yoMhlaba ene- ububanzi bungaphantsi kwama-50 m. Ukongeza kukho iinkcazo ezintsha zeManyano yeNzululwazi yeHlabathi (i-IAU) yendibano ka-Agasti 22, 2006, eyahlula iplanethi, iplanethi encinci, isatellite kunye nomzimba omncinci wesixokelelwano selanga.
Okwangoku inkcazo esetyenziswa yi NDIYATHATHA kunye nemeko yemeteoroid yileyo yento eyomeleleyo ehamba kwisithuba esiphakathi kweeplanethi, enobungakanani obuncinci kakhulu kuneasteroid kwaye inkulu kakhulu kuneathom okanye imolekyuli. Nangona kunjalo, le ngqikelelo isajongwa njengephelelwe lixesha, ayichanekanga kwaye iyimpazamo enkulu.
Umahluko phakathi kwemeteor, imeteor kunye nemeteoroid
Ukongeza koku sele kukhankanyiwe kumhlathi odlulileyo, siyaqonda ukuba kukho izigama ezisetyenziswa ngokuqhelekileyo, njengaxa iishawa zeemeteor. Yinto eyenzeka kwi astronomical emangalisa ngokwenene, nangona kunjalo ixhaphake kakhulu kunokuba siqhele ukucinga, nangona phantse kungekho mntu uyaziyo ukuba yintoni kanye kanye.
Ukwazi ukuba yintoni i-meteor shower, okokuqala kuyimfuneko ukuqwalasela ukuba yintoni umehluko phakathi kwe-meteorite, i-meteor kunye ne-meteoroid. Ngale ndlela, ngokucace ngokwaneleyo malunga ne umahluko phakathi kwezi nkwenkwezi, kuya kuba lula ukuyiqonda.
Iimeteoroids, iimeteors kunye neemeteorites
Ukuba sibhekisa kumongo okanye undoqo womxholo, sinokuthi ezi zinto zintathu zijika zibe yinto enye okanye ziphuma kwinto enye. Ngale nto sithetha ukuba kuzo zontathu iimeko ziziingceba zamatye eziye zaqhawuka emva koku Ikhayithi. Nangona kunjalo, nganye inomahluko kwaye ubukhulu becala umahluko onjalo ukwindawo ekuyo.
Nayiphi na into esemajukujukwini ibizwa ngokuba yi<em>meteoroid, engumzimba wasezulwini ekuxutyushwa ngawo kweli nqaku. Emva koku, xa i<em>meteoroid ingena kwiatmosfera yesijikelezi-langa esinguMhlaba, ibizwa ngokuba yi<em>meteor. Ekugqibeleni, ukuba ikwazi ukufikelela emhlabeni, ngoko kuya kuba njalo ebizwa ngokuba yimeteorite.
Kunika umdla kakhulu ukwahlula ngale ndlela, kuba imizimba idla ngokwahlulwa ngokwemilo yayo okanye ezinye iimpawu ezahlukileyo ezingaqwalaselwanga kule meko. Nangona kunjalo, kulapha xa iimpazamo ezenziwa rhoqo malunga ne isigama esisetyenzisiweyo. Sithetha ngegama elithi "meteor shower" kwakhona, kuba akukho ndlela enokwenzeka ngayo.
Isizathu sokungabikho okunjalo kukuba iimeteorite zezo zifikelela emhlabeni. Nangona kunjalo, into esenokubonwa esibhakabhakeni zii<em>meteors. Nangona kungekho mntu ubeke isohlwayo ngexesha lokuyibiza ngokuba yi-meteor shower. Eyona nto ilumkileyo kukuqhubeka uyibiza ngolo hlobo, ngale ndlela wonke umntu uya kuyazi ukuba yeyiphi isenzeko obhekisa kuso. Okanye ungaphinda uyibize ishawari yeemeteor kwaye usebenzise ithuba lokuchaza oko ukufundileyo kweli nqaku.
iziqwenga zecomet
Iimeteoroids ubukhulu becala malunga iziqwenga zecomet kunye ne-asteroids. Nangona kunjalo, zinokuba ngamatye avela kwiisathelayithi okanye iiplanethi ezikhutshiweyo kwiimpembelelo ezinkulu. Kwelinye icala, zisenokuba ziintsalela ekusekweni kwesixokelelwano sezijikelezi-langa. Xa ingena kwiatmosfera yesijikelezi-langa esithile, i<em>meteoroid iyatshisa ize ijike ngokupheleleyo.
Emva kokuba imeteoroid iwela umqobo womoya, igesi ehlala kwindlela elandelwa yi-meteoroid, i-ionized kwaye ngenxa yoko iyakhanya. Oku kuvelisa umzila womphunga ovuthayo obizwa ngokuba yi-meteor. Nangona kunjalo, igama layo eliqhelekileyo yinkwenkwezi yokudubula. Kwelinye icala, iibhola zomlilo zezo meteors ezinobukhulu obubonakalayo bungaphantsi kwe -4. Oku kuthetha ukuba okukhona lisezantsi ixabiso lobukhulu obubonakalayo, kokukhona kuqaqamba ngakumbi.
Lo bukhulu ngokubonakalayo ubukhulu obunayo iplanethi venus. Ukuba le planethi yeyona, phakathi kwazo zonke iinkwenkwezi kunye neeplanethi, yeyona iqaqambileyo evela eMhlabeni. Ngokusekelwe kwezo bhola zomlilo ezinobukhulu obubonakalayo obungaphantsi kweNyanga epheleleyo (-12,6), kunokuthiwa i-superbolides inokusinda kumaqhekeza afikelela emhlabeni. Amaqhekeza anjalo abizwa ngokuba ziimeteorites kwaye uninzi lweemeteorite ezisemhlabeni, ngaphandle kwezo zinkulu zesinyithi, ziphuma kwiimeteoroids.
Iinkcukacha malunga neemeteoroids
Inkqubo yelanga ayinayo kuphela iiplanethi kunye iiasteroids, kodwa ikwahlaliswa ngamaqumrhu angenakubalwa anomlinganiselo omncinci. Ezinye zeenkwenkwezi zingaphantsi kweemitha ezingama-50 ububanzi ukulungisa iingcamango, ngokukodwa ezi zibizwa ngokuba ziimeteoroids. Ngoku, ukuba ubungakanani bukhulu, bubizwa ngokuba yi-asteroid kwaye nantoni na encinci ithathwa njengothuli lwe-interplanetary.
Le mizimba ayibonakali ukusuka eMhlabeni, ngenxa yobukhulu bayo obuphantsi. Ubukho babo abugxininisi de enye yazo ingene iatmosfera emhlabeni, ishushu kakhulu ngenxa yokungqubana nayo, kumphakamo weekhilomitha ezilikhulu, ize iphele idliwe. Lo ngumbono obangela umzila oqaqambileyo obizwa ngokuba yimeteor okanye inkwenkwezi edubulayo, enye yezona zinto zinomtsalane esibhakabhakeni ebusuku.
Kukwakho namaxesha apho i-meteoroid ingasetyenziswa ngokupheleleyo kukudlula kwiatmosfera. Xa oku kusenzeka, intsalela ebizwa ngokuba yimeteorite yiyo enokufikelela kumphezulu. umphezulu womhlaba. Ukuba le ntsalela inobungakanani obuninzi, nto leyo enethamsanqa enqabileyo, impembelelo kumphezulu inokuba nobundlobongela kakhulu kwaye kungoko inokuvelisa icrater.
Kwimizila yasemajukujukwini efana neplanethi iMercury okanye isathelayithi yethu, iNyanga, iimeteorite craters ziphawuleka ngakumbi kuneplanethi yethu enguMhlaba. I-crater ayifane ibonwe kwaye oku kungenxa yokhukuliseko kunye ne-plate tectonics. Umzekelo owaziwa kakhulu mhlawumbi Barringer Meteor Crater e-Arizona, ngaphezu kwekhilomitha ububanzi, eyadalwa malunga ne-49.000 kwiminyaka eyadlulayo nge-meteoroid emashumi amahlanu eemitha ububanzi.
Ziqanjwa njani?
Iimeteoroids ubukhulu becala yenziwe ngamatye. Nangona ezinye zenziwe ngentsimbi okanye, ngokunqabileyo, umxube wezo zimbini. Ngexesha lokuphila kwabo, ngokuqhelekileyo bafumana ukungqubana kunye nokuxutywa okutshintsha ukwakheka kunye nokwakheka kweekhemikhali. Phakathi kweemeteorite ezinqabileyo ezifunyenwe kumhlaba womhlaba, ezibizwa ngokuba yi-carbonaceous chondrites, nangona kunjalo, akukho mkhondo walo naluphi na ukuguqulwa okwenzekile.
Eyona meteoroid eyaziwa kakhulu malunga nalo mba yi Yonke le meteoroid. Le meteoroid yagqabhuka phezu kweMexico ngo-1969 yaza yasasaza malunga neetoni ezi-5 zamatye kumakhulu aliqela eskweri seekhilomitha. Olu hlobo lwe-meteorite lubonisa umthombo wolwazi olubaluleke kakhulu ukwazi ukubunjwa kwenkqubo yelanga ekubunjweni kwayo.
Ngokoqikelelo, nyaka ngamnye malunga ne-40 kunye ne-80 yeetoni zamasuntswana aqinileyo afika eMhlabeni. La masuntswana abizwa ngokuba ziimeteoroids. Ezi ubukhulu becala ngamaqhekeza e-asteroids kunye ne-comets ukujikeleza ilanga kwaye, xa udibana ne-orbit yomhlaba. Ekuchaphazelekeni kwiatmosfera yethu, bafikelela kwisantya esiphakathi kwama-20 nama-72 km/s.
Kulo mba iimeko ziphathwa apho ukukhuhlana okwenzeka emoyeni oko kuphakamisa ngokukhawuleza ubushushu bemeteoroid. Ngale ndlela, zombini iimolekyuli eziyinxalenye yesiqina kunye neemolekyuli zomoya ezingqubana nawo, zikhupha amandla xa kubonwa umzila oqaqambileyo, obizwa ngokuba yimeteor.
Iimeteoroids kunye neemeteorites
Amatyala aye abonwa apho imeteoroid inkulu ngokwaneleyo kwaye ifumana phila ekuvukeni kwayo emoyeni. Nangona kunjalo, ibetha uMhlaba ngendlela yemeteorite. Kwi-20% yezinto ezijikeleze ezi meteoroids zizininzi ezijikeleza phakathi kwe-10-5 kunye ne-10-6 yeegram. Ngakolunye uhlangothi, i-80% eseleyo iphakathi kwe-10-6 kunye ne-1015 grams.
Nangona kunjalo, kwanawona mancinci amancinci, kukungena ngokukhawuleza kwezantya ezibangela iimpembelelo kunye nomoya yiba nobundlobongela kakhulu. Ngale ndlela, ukungqubana nomoya kubangela ukuba kufikelelwe amaqondo obushushu angamawaka aliqela ngokukaCelsius. Oku koko kubangela uthotho lweenkqubo zomzimba kunye neekhemikhali kwiindawo ezingaphandle zomoya, ngokubanzi phakathi kwe-80 kunye ne-100 km ukuphakama.
Uphando lwezifundo ezininzi kunye nohlalutyo lwezi nkqubo lubaluleke kakhulu kwinqanaba lethekhinoloji nakwimbono yesayensi. Yinto eyenza indawo esebenzayo kakhulu ngaphakathi inzululwazi yendawo. Umzekelo wale nto ngamasuntswana adlala indima ebalulekileyo kukhuseleko lwemishini yendawo kunye nokusebenza kweesathelayithi ezenziweyo.
Kwelinye icala, ukongeza koku babonelela ngemikhondo exabisekileyo malunga neendlela zeekhemikhali ekubonakala ukuba zikhokelele ekuveleni kombane. ubomi kwisijikelezi-langa sethu. Oku kungenxa yokuba kucingelwa ukuba ii<em>meteoroids yayizezo zazinika inxalenye yeemolekyuli eziyimfuneko ukuze zivele. Nangona kunjalo, uhlalutyo lweemeteoroids lukwasivumela ukuba siqonde ukuba zeziphi iimeko ze-physicochemical ezikhoyo kwilifu lezinto ezivela kuyo iSolar System.
Ukuqonda inkqubo
Uhlalutyo lweemeteoroids lulo oluququzelela ukuqonda iinkqubo ezenzeka ekuqaleni izigaba zokuzivelela kwayo. Kwelinye icala, esinye sezizathu ezisisiseko zokufundwa kweemeteoroids kukuba la masuntswana kanye anika ulwazi oluthe ngqo malunga nokwakheka kunye nobume bemizimba evela kuyo.
Kwiimeko ezininzi, uhlalutyo lwe-meteoroid lunokwenziwa ngeenkqubo ezisekelwe emhlabeni. Oku kuthintela imfuneko yokuqesha izixhobo ezibiza kakhulu kwiiprobe zasemajukujukwini. Kunokuthiwa ngokuchanekileyo ingcamango eyakhokelela ekuphuhlisweni kwe Iprojekthi ye-SMART (I-Spectroscopy ye-Meteoroids kwi-Atmosphere ngokusebenzisa i-Robotic Technologies).
Imeteoroid eyayinokubonwa eVenezuela
Kunyaka ophelileyo i-2016, kwizixeko ezininzi zaseVenezuela, into eqhelekileyo ebizwa ngokuba yi-astronomical I-Sporadic Meteoroid. Ngokukodwa, kwenzeka ngobusuku bukaDisemba ngoLwesihlanu i-16, xa umzimba we-incandescent wawela isibhakabhaka saseVenezuela, ukusuka kwicala laseColombia. Oku kothusa amakhulu abantu kwiindawo ezahlukahlukeneyo.
Kwimeko yaseMiranda, kwaxelwa ukuba ukukhanya okunamandla kakhulu kubonakala kuphuma eCharallave. Njengoko kuchaziwe ku-a ukukhanya okumhlophe okungqukuva esibhakabhakeni, ngokukodwa phakathi kwe-06:30 kunye ne-07:00 ebusuku malunga. Ubukhulu becala, amangqina anikela ingxelo yokuba kwakucingwa ukuba yinqwelo-moya eqhelekileyo, ekubeni kukho isikhululo seenqwelo-moya kufutshane naloo ndawo.
Nangona kunjalo, ingqikelelo yokuba yayizinqwelomoya okanye iihelikopta ayizange ivunywe, kuba okwafunyaniswayo yayikukuba ingqukuva ishiye ngasemva uhlobo oluthile lwenqwelomoya. idangatye elivuthayo eyavela yaze yanyamalala ngamanye amaxesha. Intsabelo eqhelekileyo yileyo yamangqina ale nto, eyayiza kulandela indlela yokukhanya, eyathabatha imizuzwana embalwa yaza yanyamalala esibhakabhakeni, ingashiyi mkhondo.
Kwelinye icala, emva kwentsimbi ye-07:40 ukuya kweye-08:00 ebusuku, elinye ingqina lathi liye labona isihlwele. ukukhanya okunamandla kakhulu eyayinqumla isibhakabhaka saseSabana de Mendoza, kwiphondo laseTrujillo. Njengoko kuchaziwe, umzimba okhanyayo wawunemilo emide kwaye ubonakala utshintsha umbala phakathi koluhlaza okwesibhakabhaka noluhlaza. Waphinda wabalaselisa ukuba emva kwemizuzwana emi-5, yawela ukusuka ekunene ukuya ekhohlo kwaye yakhawuleza yathi shwaka esibhakabhakeni phambi kombono omangalisayo wabo babekho.
umfanekiso ogqibeleleyo
Ukusuka kwindawo yesithathu eVenezuela apho le nto imangalisayo inokubonwa khona, ngakumbi kwiLoma del Viento yesixeko saseSan Cristóbal eTachirá, yabonwa malunga nemizuzwana engama-40, into engaqhelekanga. Babonisa ngokuthe ngqo ukuba yayikukukhanya okumhlophe okugqame kakhulu, okunokukhanya okuluhlaza, kunye nencam etsolo. Zikwabonisa ukuba ibinombala obomvu notyheli.
Njengoko kubonwa kwiphondo laseTachira, i inqanaba elikhanyayo, ilandele indlela emgceni kumphezulu womoya. Nangona kunjalo, kukho umzuzwana, ngaphambi kokuphulukana nokuwubona, apho kwakubonakala ngathi kuwa ngequbuliso. Ibali elinjalo livela kuPedro Zambrano, osebenze iminyaka ethile kwintsimi yomkhosi, onolwazi oluncinci malunga ne-air vectors, kwaye ubonisa ukuba ngenxa yobume kunye nepateni yokubhabha kwakubonakala kuye ukuba le yinto enye.
Kwilizwe laseCojedes, le nto yothusayo nayo yaxelwa kwisixeko saseSan Carlos, inika ingxelo ngesiganeko esineempawu ezifanayo nezo zenzeka kwamanye amazwe elizwe. Esi siganeko sinokujongwa ngokuthe ngqo kwi-trunk road 05, into enokubonwa yaba ukukhanya okuluhlaza ngomsila.
Ukongeza, ezininzi zichazwe izinto ezingaqhelekanga: umbala oluhlaza, kunye nokuba wawukwindlela ethe tye, ungehli, njengesiqhelo.
iingxoxo zenzululwazi
Ngokwento eboniswa yiLarense Association of Astronomy (ALDA), esi siganeko sasiyinto eqhelekileyo kwinzululwazi ngeenkwenkwezi. I-ALDA ibonisa ukuba yayiyimeteoroid, oku kuqaqamba ngakumbi kuneplanethi iVenus kwaye kungaphantsi kokuqaqamba kunesathelayithi yethu yomhlaba, iNyanga. Esi siganeko sangena kwi-atmosfera, ihamba ngendlela ethe tye kwaye ishiya umkhondo wayo ukwimo yemeteor.
Isiganeko senzeka malunga ne-07:30 pm (HLV). Nangona kunjalo, i-meteoroid ayizange ibonwe, kodwa umkhondo. Lo mkhondo ubizwa ngokuba yimeteor kwaye ukuba kukho into eye yawa phezu komhlaba, ibiya kubizwa ngokuba yimeteorite. Ndiyavumelana nawe iingcaliUkuza kuthi ga ngoku akukabikho iingxelo zeemeteorite eziye zawa kuyo nayiphi na indawo yelizwe.
Ukongeza, umbala womzimba we-incandescent nawo ujike phakathi kwe-shades eluhlaza okwesibhakabhaka kunye nohlaza. Kwelinye icala, esi siganeko silandele a umzantsi-ntshona ukuya kumzantsi-mpuma wendlela. Owona mbono ubalaseleyo wawukwidolophu yaseColombia iVillavicencio. Nangona kunjalo, baqaphela ukuba inokubonwa ngaxeshanye kwizixeko ezahlukeneyo zaseVenezuela. Oku kungenxa yokuba ukufuduka kwenzeka phezulu kwi-atmosfera.
Kwelinye icala, kwezinye zeefoto ezisasazwa kwiintanethi zentlalo, kubonwa ukuba umzimba oqaqambileyo uyanda. Izazinzulu ziyaqinisekisa ukuba esi sibakala yimbono elula, ekubeni iyimveliso yesibanzi ababekuso abantu kunye nembono enikelwa sisibhakabhaka sasekuhlaleni. Ngoko ke, i ulwalathiso lwestroke Le meteoroid ayihambelani naleyo yeemitha kwaye ihlelwa njengemanqaphanqapha.
Iindaba zeMeteoroid
Imoto yenyanga yeNASA, 'yaqhunyiswa' ziimeteoroids
Kwabakho into yasezulwini izixhobo ze-orbital Ukudubula kwenyanga kweNASA (LRO). Nangona kunjalo, akukho mfuneko yokoyika njengoko i-lunar rover iphume kuhlaselo ingenawo umkrwelo. Ekuphela kwento eyehlayo evela 'kuqhushumbo' ibe yimifanekiso engacacanga enefuthe lokushukuma kwekhamera, ibike iPhys.org. KwiNASA kukho iiasteroids ezintlanu ezikhathazayo ngokwenene kuMhlaba.
El izixhobo ze-LRO kwacaca ukuba yinkqubo yeekhamera ezintathu ezifakwe kwisiphekepheke. Iikhamera ezimbini zineengile emxinwa kwaye zithatha imifanekiso emnyama nemhlophe. Ikhamera yesithathu i-angle ebanzi kwaye ithatha imifanekiso yesisombululo esiphakathi, ikwasebenzisa izihluzi ezibonelela ngolwazi malunga neempawu kunye nemibala yendawo yenyanga.
Ngokolwazi oluqokelelwe ngo-Okthobha we-13, 2014, kwenzeka isiganeko esandula ukwaziswa emva kophando olude nolucokisekileyo ngabaphengululi kunye. Iingcali zeNASA. Imifanekiso eyaqokelelwayo yiyo eyabanceda bagqiba kwelokuba ikhamera imele ukuba ibethwe sisithuthuthu, esisisithuba esincinane esichazwe kweli nqaku. Nokuba mkhulu kancinci kunothuli lwecosmic.
Abaphengululi be Isikolo seSithuba kunye nokuJonga umhlaba, ibonisa ukuba imeteoroid yayihamba ngokukhawuleza kunembumbulu. Noko ke, iLRO ayizange iyiphephe imbumbulu, kunoko yasinda kuyo.
Ukufunda ngeplanethi iMars
Iqela elibonisiweyo liqikelele ukufunda iplanethi iMars. Esi sixhobo sikwabizwa ngokuba yi Ukuhamba kwebhendi kwaye ikamva lakhe yayikukuhamba aye kuMars. Ngokutsho kweengcali ezibonisa ukuba i-meteoroid yayimalunga ne-0,8 millimeters ngobukhulu. Noko ke, yayihamba ngesantya seekhilomitha ezisixhenxe ngomzuzwana. Le yeyona nto inokuba nefuthe elimandla kwiLRO.
I-Batmobile izalwa kwiprojekthi ye-NASA elawulwa yi-Goddard Space Flight Centre e-Greenbelt (eMaryland, e-USA). Ikwaqulunqwe kwinkqubo yoFundo. Kwaye yaziswa nge-18 kaJuni ngo-2008, ngoko ke ukusukela ngoko iqokelele isuntswana ledatha ngezixhobo zayo ezisixhenxe ezinamandla. Oku kwenza igalelo elixabisekileyo nakwinto emalunga nathi ulwazi lwenyanga.
Isitrayikhi esikhohlakeleyo
Ikhamera eseNyangeni yabethwa yimeteoroid ngo-Okthobha 2014. Esi siganeko sothusa izazinzulu i-arhente yasemajukujukwini yaseMelika, NASA. Ngokukodwa ikhamera ebekwe kwisiphekepheke serobhothi esijikeleza iNyanga, yileyo yabethwa simeteoroid encinci. Yiyo le nto yamphosayo kwaye yavelisa ukumangala okukhulu kwiingcali.
Ipateni yequbuliso nengaqhelekanga efunyenwe zizazinzulu, idwelise isiganeko njengesendle kunye novalo. Ngexesha lokujikeleza kwayo, i I-LRO ikholisa ukuvelisa imifanekiso entle ecacileyo kumphezulu weNyanga, kodwa ngeli xesha ayizange yenzeke, ngoko ke kucingelwa ukuba ibethwe simeteoroid encinci, into encinci yendalo esithubeni.
Babona i-meteoroid kwisibhakabhaka sase-Asturian
NgoJanuwari walo nyaka, i-meteoroid yabonwa esibhakabhakeni sasebusuku kwimpuma ye-Asturias, ngaphambi nje kokuba yahlukane xa idibana nomoya woMhlaba. Siyazi kakuhle ukuba i-meteoroids ezininzi ziziqwenga ze-comets kunye ne-asteroids, nangona zinokuthi zibe ngamatye avela kwiisathelayithi okanye iiplanethi eziye zakhutshwa kwiimpembelelo ezinkulu okanye i-debris ekubunjweni kwenkqubo yelanga.
Ngokutsho koko kubonisiwe, i-meteoroid yayiluhlobo olubizwa ngokuba yi-"bolide" kunye nokubonwa okurekhodiweyo nge-21.48: XNUMX p.m. Yiyiphi wanqumla isibhakabhaka singise entshona. Njengoko kubonisiwe ngamangqina okuzibonela, i-fireball yaphela emva kwemizuzu embalwa.
Nakuba kunjalo, esi asikuphela kwesiganeko apho kuye kwafunyaniswa ukuba kukho ingozi yemeteoroid. La masuntswana mancinane awayongozi ngenxa yobukhulu bawo, kodwa ngenxa yesantya ahamba ngaso emajukujukwini. Kungenxa yesi sizathu ukuba ngexesha lokuchaphazela kunye nomnye umzimba wendawo, uvelisa a Impembelelo enamandla. Injalo ke imeko yento eyenzekileyo kwiindaba zangaphambili: ukungqubana kwemeteoroid nekhamera yesithuba
Ukusukela ngoku ukuya phambili sinokumisela amagama afanelekileyo okusetyenziswa, xa sijonga emhlabeni umzimba wendawo elixutyushwa kweli nqaku. Kubonakala kungakholelekiyo ukuba intwana enye evela kwi-comets okanye i-asteroid inokuba yimizimba emithathu efanayo kodwa kumanqanaba ahlukeneyo. Ngokwengqiqo inokuthelekiswa nomntu: usana, umntwana, umntu ofikisayo, umntu omdala nosele ekhulile. Ngumntu omnye, kodwa ngokwamanqanaba ahlukeneyo.
Kule meko, iqhekeza okanye iqhekeza i-comet okanye i-asteroid extracts nayo ithatha amagama ahlukeneyo ngezigaba: imeteoroid, imeteor kunye nemeteorite. Kuxhomekeke ekubeni ukweliphi inqanaba. I<em>meteoroid yile sijongana nayo ekuhambeni kweli nqaku, ngoxa i<em>meteor isekubeni idlula kwiatmosfera yomhlaba, zona zi<em>meteors. Kwelam icala, ixesha elifanelekileyo lesiganeko esenzeka eVenezuela yayisisimeteor.
kakhulu nangona ngokwentatheli nangokwenzululwazi, lo mzimba wasezulwini uye waphathwa eVenezuela njenge meteoroid. Enye yeempawu ezivezwa yimeteor, ukongezelela, ngumsila okanye umzila oyishiya ngasemva xa ihamba. Ekugqibeleni, inqanaba lokugqibela lale ntwana kuxa iba yimeteorite. Eli lelona nqanaba liyingozi kakhulu, ekubeni i-particle encinci enjalo ingaba yi-chaos yangempela.
Iimeteorite zinokubeka emngciphekweni zonke iintlobo zobomi ezichaphazela zona. Ekubeni eli nqanaba lelitye liqala ukusebenza kwaye libizwa ngokuba, xa lithe lafika eMhlabeni. Ngethamsanqa, ezi meko azenzeki rhoqo. Ke okwangoku, masithembe ukuba ilitye elihamba emajukujukwini lisaqhubeka linegama le meteoroid, ekubeni i meteor ikwasisilumkiso sento enokwenzeka kwaye impembelelo elandelayo.
