I-Los ama-meteoroids ziyimizimba emincane engaphakathi kwesimiso sonozungezilanga futhi cishe, phakathi kuka-0,1mm kuya ku-50m ububanzi, ubukhulu. Umkhawulo ongaphezulu ngokosayizi othintekayo, ungama-50m. Lona ubukhulu obusetshenziselwa ukukwazi ukuhlukanisa kusuka kuma-comet nama-asteroids. Ngakolunye uhlangothi, umkhawulo kasayizi ophansi ngu-100 µm. Ngale ndlela ihluke othulini lwe-cosmic.
Nokho, imikhawulo kasayizi ngokuvamile ayisetshenziswa ngokuqinile kakhulu. Njengoba ingaqondakali ukuqokwa kwezinto eziseduze nale mikhawulo. Empeleni, incazelo esetshenziswa kakhulu yileyo ethi i-meteoroid iyindikimba yasezulwini ephakathi kuka-0,1mm no-50m. Lokhu okukhulunywe ngakho ngenhla, empeleni kuvela encazelweni yeRoyal Astronomical Society.
Le ncazelo iphinde ihlanganiswe naleyo ye-Near-Earth meteoroid, edluliselwa kuma-meteoroids nawo angekho eduze noMhlaba. Incazelo izoba yileyo yezinto ezinemizila eseduze noMhlaba nge- ububanzi bungaphansi kwama-50 m. Ngaphezu kwalokho kunezincazelo ezintsha ze-International Astronomical Union (IAU) yomhlangano wangomhla zingama-22 kuNcwaba, 2006, ezihlukanisa iplanethi, iplanethi encane, isathelayithi kanye nomzimba omncane wesimiso sonozungezilanga.
Okwamanje incazelo esetshenziswa yi- I-IAU ngetemu le-meteoroid yileyo yento eqinile ehamba emkhathini ophakathi kwamaplanethi, enosayizi omncane kakhulu kune-asteroid futhi inkulu kakhulu kune-athomu noma i-molecule. Kodwa-ke, lokhu kucatshangelwa kwengqondo kusabhekwa njengokuyisidala, njengokunganembile futhi kunephutha elibanzi.
Umehluko phakathi kwe-meteor, i-meteor kanye ne-meteoroid
Ukwengeza kulokho okukhulunywe ngakho endimeni edlule, siyaqonda ukuthi kunamagama asetshenziswa kakhulu, njengalapho ama-meteor shower. Kuyinto yesayensi yezinkanyezi emangalisa ngempela, kodwa ivame kakhulu kunalokho esivame ukucabanga, nakuba cishe akekho owaziyo ukuthi iyini ngempela.
Ukuze wazi ukuthi i-meteor shower iyini, okokuqala kudingekile ukucabangela ukuthi yini umehluko phakathi kwe-meteorite, i-meteor kanye ne-meteoroid. Ngale ndlela, ngokucace ngokwanele mayelana ne umehluko phakathi kwalezi zinkanyezi, kuyoba lula kakhulu ukuyiqonda.
Ama-meteorites, ama-meteor nama-meteorites
Uma sibhekisela engqikithini noma engqikithini yendaba, singasho ukuthi lezi zinto ezintathu ziphenduka ziyefana noma zivela ngokufanayo. Ngalokhu sisho ukuthi kuzo zontathu lezi zimo ziyizingcezu zamatshe eziye zahlukaniswa kulandela a Ikhayithi. Nokho, ngayinye inomehluko futhi ngokuyinhloko umehluko onjalo usendaweni yawo.
Noma iyiphi into esemkhathini ibizwa ngokuthi i- meteoroid, okuyindikimba yasezulwini okuxoxwa ngayo kulesi sihloko. Ngemva kwalokhu, lapho i- meteoroid ingena emkhathini weplanethi enguMhlaba, ibizwa ngokuthi i- meteor. Ekugcineni, uma ikwazi ukufinyelela phansi, ngaleso sikhathi kuyoba njalo ebizwa ngokuthi yi-meteorite.
Kuyathakazelisa kakhulu ukulihlukanisa ngale ndlela, njengoba imizimba ivame ukuhlukaniswa ngokuma kwayo noma ezinye izici ezihlukile ezingacatshangelwa kulokhu. Nokho, kulapha lapho amaphutha ngokuvamile enziwa mayelana amagama asetshenzisiwe. Siphinde sikhulume ngegama elithi "meteor shower" njengoba ingekho indlela lokhu okwenzeka ngayo.
Isizathu sokungabi khona okunjalo ukuthi ama-meteorite yilawo afika phansi. Nokho, okungase kubonakale esibhakabhakeni ama- meteor. Yize kungekho muntu oke wafaka unswinyo ngesikhathi esibiza nge-meteor shower. Into ehlakaniphe kakhulu wukuqhubeka ukubiza kanjalo, ngale ndlela wonke umuntu uzokwazi ukuthi yisiphi isigameko okhuluma ngaso. Noma ungaphinda uyibize ishawa ye-meteor futhi usebenzise ithuba lokuchaza lokho okufundile kulesi sihloko.
izingcezu zenkanyezi enomsila
I-Meteoroids ikakhulukazi imayelana izingcezu zenkanyezi enomsila kanye nama-asteroids. Kodwa-ke, kungenzeka futhi kube amatshe avela kumasathelayithi noma amaplanethi akhishwe emithelela emikhulu. Ngakolunye uhlangothi, zingase zibe izinsalela ekubunjweni kwesimiso sonozungezilanga. Lapho ingena emkhathini weplanethi ethile, i-meteoroid iyashisa futhi ihwamuke kancane kancane.
Ngemva kokuwela i-meteoroid umgoqo womkhathi, igesi ehlala endleleni elandelwa i-meteoroid, i-ionized futhi ngenxa yalokho iyakhanya. Lokhu kukhiqiza umzila womhwamuko ocwebezelayo obizwa ngobuchwepheshe ngokuthi i-meteor. Nokho, igama layo elivamile inkanyezi yokudubula. Ngakolunye uhlangothi, amabhola omlilo yilawo ma meteor ubukhulu bawo obubonakalayo bungaphansi kuka -4. Lokhu kusho ukuthi uma liphansi inani lobukhulu obubonakalayo, ukukhanya kwalo kukhulu.
Lobu bukhulu ngokusobala ubukhulu obunabo iplanethi venus. Njengoba le planethi yiyona, phakathi kwazo zonke izinkanyezi namaplanethi, ekhanya kakhulu evela eMhlabeni. Ngokusekelwe kulawo mabhola anomlilo anobukhulu obubonakalayo obungaphansi kobeNyanga egcwele (-12,6), kungase kushiwo ukuthi ama-superbolide angasinda ezingcezuni ezifika phansi. Izingcezu ezinjalo ziyilokho okubizwa ngokuthi ama-meteorite futhi iningi lama-meteorite asemhlabeni, ngaphandle kwezinkulu zensimbi, zivela kuma-meteoroids.
Imininingwane mayelana nama-meteoroids
Isimiso sonozungezilanga asinawo amaplanethi namaplanethi ama-asteroid, kodwa futhi igcwele izindikimba ezingenakubalwa zobukhulu obuncane. Ezinye zezinkanyezi zingaphansi kwamamitha angama-50 ububanzi ukulungisa imibono, ikakhulukazi lezi zibizwa ngokuthi ama-meteoroid. Manje, uma usayizi mkhulu, ubizwa ngokuthi i-asteroid futhi noma yini encane ibhekwa njengothuli lwe-interplanetary.
Le mizimba ayibonakali eMhlabeni, ngenxa yobukhulu bayo obuphansi. Ubukhona babo abugqanyisiwe kuze kube yilapho omunye wabo engena umkhathi yasemhlabeni, ishisa kakhulu ngenxa yokungqubuzana nayo, endaweni ephakeme ngamakhilomitha ayikhulu, futhi igcine idliwe. Lesi isenzakalo esibangela umzila okhanyayo obizwa ngokuthi i-meteor noma inkanyezi edubulayo, okungenye yezinto ezihlaba umxhwele kakhulu esibhakabhakeni ebusuku.
Kukhona nezikhathi lapho i-meteoroid ingadliwa ngokuphelele ukuhamba kwayo emkhathini. Uma lokhu kwenzeka, insalela ebizwa ngokuthi i-meteorite iyona engafinyelela phezulu. umhlabathi. Uma lensalela inosayizi omkhulu, okuyinto ngenhlanhla eyivelakancane, umthelela ongaphezulu ungaba nodlame kakhulu futhi kungaleso sikhathi lapho kungase kubangele umgodi.
Emizimbeni yasemkhathini njengeplanethi iMercury noma isathelayithi yethu, iNyanga, ama-meteorite craters abonakala kakhulu kunaseplanethi yethu enguMhlaba. I-crater ayivamisile ukubonakala futhi lokhu kungenxa yokuguguleka komhlabathi kanye ne-plate tectonics. Isibonelo esaziwa kakhulu kungenzeka Barringer Meteor Crater e-Arizona, ngaphezu kwekhilomitha ububanzi, eyadalwa eminyakeni engaba ngu-49.000 edlule nge-meteoroid engamamitha angamashumi amahlanu ububanzi.
Aqanjwa kanjani?
Iningi lama-meteoroids eyenziwe ngamatshe. Nakuba ezinye zenziwe ngensimbi noma ngisho, okungajwayelekile, ingxube yazo zombili. Phakathi nokuphila kwazo, zivame ukungqubuzana futhi zixubane okushintsha ukwakheka kwazo kanye nokwakheka kwamakhemikhali. Phakathi kwama-meteorite angavamile atholakale ebusweni bomhlaba, abizwa ngokuthi ama-carbonaceous chondrites, nokho, akukho mkhondo wanoma yikuphi ukuguqulwa okwenzekile.
I-meteoroid eyaziwa kakhulu ngokuphathelene nalesi sici yile Konke ku-meteoroid. Le meteoroid yaqhuma phezu kweMexico ngo-1969 futhi yasakaza cishe amathani ama-5 amatshe endaweni engamakhulu ambalwa amakhilomitha-skwele. Lolu hlobo lwe-meteorite lumelela umthombo wolwazi olubaluleke kakhulu ukwazi ukwakheka kwesimiso sonozungezilanga ekubunjweni kwayo.
Ngokwezilinganiso, unyaka ngamunye cishe amathani angama-40 kanye ne-80 ezinhlayiya eziqinile afika eMhlabeni. Lezi zinhlayiya yizo ezibizwa ngokuthi ama-meteoroid. Lezi izingcezu eziphukile zama-asteroids kanye nenkanyezi enomsila zungeza ilanga nokuthi, lapho uphambana nomjikelezo woMhlaba. Lapho zithinta umkhathi wethu, zifinyelela isivinini esiphakathi kuka-20 no-72 km/s.
Kulesi sici izimo ziphathwa lapho ukungqubuzana okwenzeka emoyeni yikho okuphakamisa kungazelelwe izinga lokushisa le-meteoroid. Ngale ndlela, kokubili ama-molecule ayingxenye yokuqinile nama-molecule omoya angqubuzana nawo, akhipha amandla lapho kubukwa umzila okhanyayo, obizwa ngokuthi i-meteor.
Ama-meteorites nama-meteorite
Amacala aye aqashelwa lapho i-meteoroid inkulu ngokwanele futhi ithola khona phila ekuvukeni kwayo emkhathini. Nokho, ishaya eMhlabeni ngesimo se-meteorite. Ku-20% walokho okuzungezile la ma-meteoroids kukhona uquqaba oluzungeza phakathi kuka-10-5 no-10-6 amagremu. Ngakolunye uhlangothi, ama-80% asele aphakathi kuka-10-6 no-1015 amagremu.
Kodwa-ke, ngisho nezinhlayiya ezincane kunazo zonke, yi-velocities yokungena esheshayo ebangela ukuthi bangene imithelela nomkhathi abe nodlame kakhulu. Ngale ndlela, ukungqubuzana komoya kubangela ukuba kufinyelelwe amazinga okushisa ayizinkulungwane ezimbalwa zama-degree Celsius. Yilokhu okucupha lonke uchungechunge lwezinqubo zomzimba nezamakhemikhali ezindaweni ezingaphandle kakhulu zomkhathi, ngokuvamile phakathi kuka-80 no-100 km ukuphakama.
Uphenyo lwemikhakha eminingi kanye nokuhlaziywa kwalezi zinqubo kubaluleke kakhulu kokubili ezingeni lezobuchwepheshe kanye nombono wesayensi. Yilokho okwenza indawo esebenza kakhulu ngaphakathi kwe isayensi yesikhala. Isibonelo salokhu yizinhlayiya ezidlala indima ebalulekile ekuphepheni kohambo lwasemkhathini kanye nokusebenza kwamasathelayithi okwenziwa.
Ngakolunye uhlangothi, ngaphezu kwalokhu banikeza izinkomba ezibalulekile mayelana nezinqubo zamakhemikhali ngokusobala eziholele ekubonakaleni kwe ukuphila emhlabeni wethu. Lokhu kungenxa yokuthi kucatshangwa ukuthi ama- meteoroid yiwo anikeza ingxenye yama- molecule adingekayo ukuze avele. Kodwa-ke, ukuhlaziya ama-meteoroids yikho futhi okusivumela ukuthi sithole ukuthi yiziphi izimo ze-physicochemical ezazikhona efwini lezinto okwakhiwe ngazo iSolar System.
Ukuqonda inqubo
Ukuhlaziywa kwama-meteoroid yikho okusiza ukuqonda izinqubo ezenzeka ekuqaleni izigaba zokuvela kwayo. Ngakolunye uhlangothi, esinye sezizathu eziyinhloko zocwaningo lwama- meteoroids ukuthi lezi zinhlayiya yizo kanye ezinikeza ulwazi oluqondile mayelana nokwakheka kanye nemvelo yemizimba evela kuyo.
Ezimweni eziningi, ukuhlaziya i-meteoroid kungenziwa ngamasistimu asekelwe phansi. Lokhu kugwema isidingo sokuqasha imishini ebiza kakhulu kuma-probe emkhathini. Kungashiwo ukuthi yiwona mqondo owaholela ekuthuthukisweni kwe Iphrojekthi ye-SMART (Spectroscopy of Meteoroids in the Atmosphere by Robotic Technologies).
I-meteoroid engabonwa isuka eVenezuela
Ngonyaka odlule i-2016, emadolobheni amaningana aseVenezuela, into evamile yezinkanyezi ebizwa ngokuthi I-Sporadic Meteoroid. Ikakhulukazi, kwenzeka ngobusuku bukaZibandlela ngoLwesihlanu mhla ziyi-16, lapho indikimba ye-incandescent inqamula esibhakabhakeni saseVenezuela, isuka ngaseColombia. Lokhu kwamangaza amakhulu abantu ezindaweni ezihlukahlukene.
Esifundeni saseMiranda, kubikwe ukuthi ukukhanya okunamandla kakhulu kubonakala kuphuma eCharallave. Njengoba kuchazwe ku-a ukukhanya okumhlophe okuyindilinga esibhakabhakeni, ikakhulukazi phakathi kuka-06:30 no-07:00 ebusuku cishe. Ngokuyinhloko, ofakazi babika ukuthi kwakucatshangwa ukuthi iyindiza evamile, njengoba kunesikhumulo sezindiza eduze kwaleyo ndawo.
Kodwa-ke, umbono wokuthi kwakuyizindiza noma izindiza ezinophephela emhlane awuzange utholakale, ngoba okwatholwa ukuthi inkundla ishiye uhlobo oluthile ilangabi elivuthayo okwavela futhi kwanyamalala ngezinye izikhathi. Ukusabela okuvamile yilokho kofakazi balesi senzakalo, okwakuwukulandela indlela yokukhanya, eyathatha imizuzwana embalwa yabe isinyamalala esibhakabhakeni, kungashiyi lutho.
Ngakolunye uhlangothi, ngokuhamba kwesikhathi, phakathi kuka-07:40 no-08:00 ntambama, omunye ufakazi wathi wayebone ukukhanya okunamandla kakhulu eyayinqamula esibhakabhakeni saseSabana de Mendoza, esifundazweni saseTrujillo. Njengoba kuchaziwe, umzimba okhanyayo wawunomumo omude futhi wawubonakala ushintsha umbala phakathi kokuluhlaza okwesibhakabhaka nokuluhlaza. Uphinde wagqamisa ukuthi ngemva kwemizuzwana emi-5, yanqamula isuka kwesokudla iye kwesobunxele yabe isinyamalala ngokushesha esibhakabhakeni ngaphambi kokubuka ngokumangala kwababekhona.
ukubonwa okuphelele
Kusukela endaweni yesithathu eVenezuela lapho lesi sigameko esimangalisayo singabonwa khona, ikakhulukazi eLoma del Viento yedolobha laseSan Cristóbal eTachirá, sabonwa cishe imizuzwana engama-40, into engavamile. Babonisa ngokunembile ukuthi kwakuwukukhanya okumhlophe okuqine kakhulu, okukhanyayo okuluhlaza okwesibhakabhaka, nephoyinti elicijile. Ziphinde ziveze ukuthi ibinombala obomvu nophuzi.
Njengoba kubonakala esifundeni saseTachira, i indawo ekhanyayo, kulandele indlela ewumugqa endaweni yomoya. Nokho, kwaba khona umzuzwana, ngaphambi kokungawuboni, lapho kwabonakala kuwa ngokuzumayo. Ukulandisa okunjalo kwavela kuPedro Zambrano, owakhonza iminyaka ethile emkhakheni wezempi, onolwazi oluncane mayelana nama-vector asemoyeni, futhi ubonisa ukuthi ngenxa yokuma kanye nephethini yendiza kuye kwabonakala sengathi lokhu kwakungokunye.
Esifundeni saseCojedes, lesi sigameko esishaqisayo sabikwa nasedolobheni laseSan Carlos, sinikeza indaba ngesenzakalo esinezici ezifanayo nalokho okwenzeka kwezinye izifundazwe zezwe. Lo mcimbi ubungabhekwa ngqo ku-trunk road 05, obekungabonwa wu-a ukukhanya okuluhlaza nomsila.
Ngaphezu kwalokho, kuchazwe eziningana izinto ezingavamile: umbala oluhlaza, nokuthi ubusendleleni evundlile, ungehli, njengoba kuvamise ukwenzeka.
izimpikiswano zesayensi
Ngokwalokho okushiwo yi-Larense Association of Astronomy (ALDA), lesi senzakalo sasiyisenzakalo esivamile sesayensi yezinkanyezi. I-ALDA ikhombisa ukuthi kwakuyi-meteoroid, lokhu kucwebezela kuneplanethi i-Venus futhi kungaphansi kokukhanya kunesathelayithi yethu yasemhlabeni, iNyanga. Lesi simo sangena emkhathini, sihamba umugqa oqondile futhi sishiya umkhondo wawo usesimweni se-meteor.
Umcimbi wenzeke cishe ngo-07:30 pm (HLV). Nokho, i-meteoroid ayizange ibonakale, kodwa umkhondo. Lo mkhondo ubizwa ngokuthi i-meteor futhi uma kukhona okuwele phezulu, bekungabizwa ngokuthi i-meteorite. Ngivumelana nawe ongotiKuze kube manje akukaze kube nemibiko yama-meteorite awe kunoma iyiphi indawo yezwe.
Ngaphezu kwalokho, umbala womzimba we-incandescent nawo waphenduka phakathi kwe-shades eluhlaza okwesibhakabhaka nokuhlaza. Ngakolunye uhlangothi, lesi simo silandela a eningizimu-ntshonalanga kuya eningizimu-mpumalanga trajectory. Ukubonwa okuhle kakhulu bekusedolobheni laseColombia iVillavicencio. Kodwa-ke, bayaqaphela ukuthi ingabonakala ngasikhathi sinye emadolobheni ahlukene aseVenezuela. Lokhu kungenxa yokuthi ukufuduka kwenzeka phezulu emkhathini.
Ngakolunye uhlangothi, kwezinye zezithombe ezisabalele ezinkundleni zokuxhumana, kubonakala sengathi umzimba okhazimulayo ukhula. Ososayensi bayakuqinisekisa ukuthi leli qiniso liwumbono olula, njengoba liwumkhiqizo we-latitude abantu ababekuyo kanye nombono onikezwa isibhakabhaka sendawo. Ngakho-ke, i- isiqondiso sohlangothi yale meteoroid ayihambisani naleyo yemisebe futhi ihlukaniswa njengengavamile.
Izindaba ze-Meteoroid
Imoto yenyanga ye-NASA, 'yaqhunyiswa' ama-meteoroids
Into yasezulwini ishaye i imishini ye-orbital I-NASA moonshot (LRO). Nokho asikho isidingo sokwesaba njengoba i-lunar rover iphume ingenamyocu ekuhlaseleni. Okuwukuphela kwemiphumela 'ekuqhunyisweni kwebhomu' kube izithombe ezingacacile ezinomphumela wokuzamazama kwekhamera, kubika i-Phys.org. Ku-NASA kunezinkanyezi ezinhlanu ezikhathazayo ngempela zoMhlaba.
El Imishini ye-LRO kuvele ukuthi iyisistimu yamakhamera amathathu efakwe kumkhumbi-mkhathi. Amakhamera amabili ane-engeli ewumngcingo futhi athwebula izithombe ezimnyama nezimhlophe ezinokulungiswa okuphezulu. Ikhamera yesithathu ine-engeli ebanzi futhi ithwebula izithombe zokucaca okulingene, futhi isebenzisa izihlungi ezinikeza ulwazi mayelana nezakhiwo nemibala yendawo yenyanga.
Ngokolwazi olwaqoqwa mhla ziyi-13 kuMfumfu wezi-2014, kwenzeka isigameko esisanda kwaziswa ngemva kophenyo olude nolucocise olwenziwa osolwazi kanye nocwaningo. ochwepheshe be-NASA. Izithombe ezaqoqwa yizona ezabasiza ukuba baphethe ngokuthi ikhamera kumelwe ukuba ishaywe i-meteoroid, into encane yasemkhathini echazwe kulesi sihloko. Ngisho nokuba mkhulu kunothuli lwe-cosmic.
Izazi ze Isikole Somkhathi Nokuhlola Umhlaba, bonisa ukuthi i-meteoroid yayihamba ngokushesha kakhulu kunenhlamvu. Nokho, i-LRO ayizange iyivimbe inhlamvu, kunalokho yasinda kuyo.
Ukufunda ngeplanethi i-Mars
Ithimba elibonisiwe lalilinganisele ukufunda iplanethi i-Mars. Le divayisi ibizwa nangokuthi I-Batmobile futhi isiphetho sakhe sasiwukuba ahambe aye eMars. Ngokwalokho ochwepheshe abakubonisayo, i-meteoroid yayicishe ibe ngamamilimitha angu-0,8 ngosayizi. Nokho, ibihamba ngesivinini esingamakhilomitha ayisikhombisa ngomzuzwana. Yilokhu obekungaveza umthelela oqinile nge-LRO.
I-Batmobile izalwa kuphrojekthi ye-NASA ephethwe yi-Goddard Space Flight Centre eGreenbelt (eMaryland, e-USA). Iphinde ifakwe kuhlaka ohlelweni lwe-Discovery. Futhi yethulwa ngoJuni 18, 2008, ngakho kusukela lapho isiqoqe idatha encane kakhulu ngezinsimbi zayo eziyisikhombisa ezinamandla. Lokhu kwenza umnikelo obalulekile futhi kulokho okumayelana nathi ulwazi lwenyanga.
Isiteleka esinonya
Ikhamera yaseNyangeni yashaywa yi-meteoroid ngo-Okthoba 2014. Lo mcimbi umangaze ososayensi i-united states space agency, NASA. Ikakhulukazi ikhamera esemkhathini werobhothi ozungeza iNyanga, yiyona eshaywe yi-meteoroid encane. Yikho lokhu okwamlaxaza kwaveza ukumangala okukhulu kochwepheshe.
Iphethini engazelelwe nengajwayelekile etholwe ososayensi, ibhale umcimbi njengononya futhi wethukile. Ngesikhathi sokujikeleza kwayo, i- I-LRO ngokuvamile kuvame ukukhiqiza izithombe ezinhle ezicace kakhulu ebusweni beNyanga, kodwa kulokhu akwenzekanga, ngakho kucatshangwa ukuthi ishaywe yi-meteoroid encane, into encane yemvelo emkhathini.
Babona i-meteoroid esibhakabhakeni sase-Asturian
NgoJanuwari walo nyaka, i-meteoroid yabonwa esibhakabhakeni sasebusuku empumalanga ye-Asturias, ngaphambi nje kokuhlakazeka lapho ithintana nomkhathi woMhlaba. Sazi kahle ukuthi ama-meteoroid amaningi ayizingcezu zenkanyezi enomsila nama-asteroids, nakuba angase futhi abe amatshe avela kumasathelayithi noma amaplanethi akhishwe emithelela emikhulu noma imfucumfucu evela ekwakhiweni kwesimiso sonozungezilanga.
Ngokwalokho okubonisiwe, i-meteoroid yayiwuhlobo olubizwa ngokuthi "i-bolide" ngokubona okuqoshwe ngo-21.48:XNUMX p.m. Yikuphi weqa isibhakabhaka elibangise entshonalanga. Njengoba kuboniswe ngofakazi bokuzibonela, i-fireball yahlakazeka ngemva kwemizuzu embalwa.
Noma kunjalo, lesi akusona ukuphela kwesehlakalo lapho kutholwe khona ukuphahlazeka kwe-meteoroid. Lezi zinhlayiya ezincane aziyona ingozi ngenxa yobukhulu bazo, kodwa ngenxa yejubane ezihamba ngalo emkhathini. Kungenxa yalesi sizathu ukuthi ngesikhathi sokuthinta nomunye umzimba wendawo, ikhiqiza a Umthelela onamandla. Kunjalo ke okwenzeka ezindabeni ezedlule: ukushayisana kwe-meteoroid nekhamera yesikhala
Kusukela manje kuqhubeke singakwazi ukunquma amagama afanelekile okufanele asetshenziswe, lapho sibona ngeso lengqondo sisemhlabeni umzimba wesikhala okuxoxwa ngakho kulesi sihloko. Kubonakala kungakholeki ukuthi inhlayiya efanayo evela kuma-comets noma i-asteroid ingaba imizimba emithathu efanayo kodwa ngezigaba ezahlukene. Ngokwezibalo, ingafaniswa nomuntu: ingane, ingane, intsha, umuntu omdala nasebekhulile. Ngumuntu ofanayo, kodwa ngezigaba ezahlukene.
Kulokhu, izinhlayiya noma ucezu inkanyezi enomsila noma i-asteroid extracts nayo ithatha amagama ahlukene ngezigaba: i-meteor, i-meteor kanye ne-meteorite. Kuya ngokuthi ukusiphi isigaba. I-meteoroid yiyona esikhuluma ngayo phakathi nalesi sihloko, kanti i-meteor uma idlula umkhathi womhlaba, wona angama- meteor. Ngokwami, igama elifanele lomcimbi esenzeka eVenezuela kwakuyi-meteor.
kakhulu nakuba ngokobuntatheli nangokwesayensi, lendikimba yasezulwini iye yaphathwa njenge-meteoroid e-Venezuela. Esinye sezici ezivezwa yi-meteor, ngaphezu kwalokho, umsila noma umzila owushiya ngemuva lapho uhamba. Ekugcineni, isigaba sokugcina sale zinhlayiya yilapho iba yi-meteorite. Lesi yisigaba esiyingozi kakhulu, njengoba inhlayiyana encane kangaka ingaba isiphithiphithi sangempela.
Ama-meteorite angabeka engcupheni zonke izinhlobo zempilo anomthelela kuzo. Njengoba lesi sigaba sedwala siqala ukusebenza futhi sibizwa kanjalo, uma sifika eMhlabeni. Ngenhlanhla, lezi zimo azenzeki njalo. Ngakho okwamanje, masithembe ukuthi idwala elihamba emkhathini lisaqhubeka linegama le- meteoroid, njengoba i- meteor nayo iwuphawu oluyisixwayiso lokuthi kungenzeka futhi umthelela olandelayo.
