Ngikuphi okuhlukileko kuneGreyidini netshe elisemkhathini we meteorite. Indaba ngalezi eziningi nezinye izakhamuzi zaseMpumalanga yonke

On ehlobo nobusuku obufudumele kuyinjabulo ukungcebeleka ngaphansi izinkanyezi, kubhekwe nemilaza ngokuyisimangaliso ke, yenza isifiso lapho inkanyezi sokudubula. Noma indiza le inkanyezi enomsila? Noma kungenzeka meteorite? Mhlawumbe phakathi romantics kanye abathandi Okuningi Astronomy ochwepheshe kuka phakathi izivakashi izinkanyezi.

isikhala ongaqondakali

kuphakama njalo Imibuzo e nokucabanga isikhala izinto, funa izimpendulo, futhi izimfihlakalo wasezulwini - kanye imikhondo izincazelo ngokwesayensi. Lapha, ngokwesibonelo, + iyahluka kwenye netshe elisemkhathini we meteorite? Akuwona wonke umfundi (ngisho abadala) ngokushesha bakwazi ukuphendula lo mbuzo. Kodwa ake ngiqale indaba ekuqaleni.

asteroyidi

Ukuze siqonde umahluko phakathi netshe elisemkhathini we kwemvula yezinkanyezi ezinomsila, kubalulekile ukuba sichaze amazwi athi "netshe elisemkhathini". Igama ivela ngolimi lwesiGreki kusho "like inkanyezi", ngoba lezi zindikimba zasemkhathini lapho ayebheka ngokusebenzisa isibonakude wakhumbuza yezinkanyezi ezingaphezu kwezigidi amaplanethi. Asteroids phambi 2006 ngokuvamile okuthiwa amaplanethi ezincane. Ngempela, ukujikeleza asteroyidi ngokuvamile akahlukile kusukela mayelana nokuhamba kwamaplanethi, ngoba liphinde kwenzeka njengoba uzungeza ilanga. Kusukela asteroyidi ezivamile kwamaplanethi zinezikhathi usayizi encane. Ngokwesibonelo, ngobukhulu elisemkhathini Ceres has a ububanzi km 770 kuphela.

Ukuphi abakhileyo inkanyezi-isikhala? asteroyidi Iningi udlulele isikhathi eside wafunda uzungeza isikhala phakathi Jupiter ne-Mars. Kodwa ezinye amaplanethi ezincane kodwa ewela emzileni Mars (njengoba, ngokwesibonelo, le nguzunga Icarus), kanye namanye amaplanethi, futhi ngezinye izikhathi ngisho oza Sun eduze kuka Mercury.

emkhathini

Ngokungafani asteroyidi, emkhathini - akusiyo abakhileyo yonke, futhi izithunywa zakhe. Ngamunye the Earthlings ungabona meteorite ngamehlo ami wamthinta ngezandla zabo. Esikhathini iminyuziyamu namaqoqo yangasese egcinwe inani elikhulu lazo, kodwa mangisho ukuthi emkhathini ibukeke kahle shabby. Iningi lawo abantu izigaxa grey noma sinombala-black lamatshe yensimbi.

Ngakho, kungenzeka ukuba baqonde umahluko phakathi netshe elisemkhathini we meteorite. Kodwa lokho kungaba ukuhlanganisa? Kukholakala ukuthi emkhathini izinsalela elincane asteroyidi. Amatshe, sithwele emkhathini, nqwamana nomunye, futhi ngezinye izikhathi izingcezwana yabo ifinyelela surface eMhlabeni.

Isenzakalo esidume kunazo zonke eRussia Tunguska meteorite is, wayewile ehlathini 30 Juni 1908. Esikhathini esidlule yamuva, okungukuthi ngo-February 2013, idonse emhlabeni wonke ukunakwa Chelyabinsk kwemvula yezinkanyezi ezinomsila, babutha izingcezwana eziyizinsalela kabani eminingi etholakale endaweni echibini Chebarkul ku Chelyabinsk esifundeni.

Ngenxa emkhathini, uhlobo izivakashi kuvela emkhathini, kanti ososayensi, futhi nabo, futhi bonke abakhileyo Umhlaba, nethuba elihle kakhulu ukuze ufunde mayelana nokwakheka kwe ezisemkhathini uthole umqondo mayelana ngemvelaphi yezulu nomhlaba.

emkhathini

Igama elithi "Meteor" futhi "meteorite" livela lesiGreki impande nenjongo ukuhunyushwa 'sasezulwini'. Siyazi ukuthi kwemvula yezinkanyezi ezinomsila, futhi uhluke kanjani kusuka Meteor, ngeke kube nzima ukuqonda.

Meteor - lokhu akukona into ethize esibhakabhakeni kanye mkhuba asemkhathini ukuthi ifana kuthi bani ukukhanya. Kwenzeka lapho lowo doti ashisiwe lezinkanyezi ezinomsila kanye asteroyidi e emkhathini woMhlaba.

Meteor - lena inkanyezi sokudubula. Kungaba ivele kwababukele ukundiza emkhathini noma emkhathini woMhlaba ukuba ashise.

Qonda ngaphandle emkhathini ababonakali ngezikhundla kusukela asteroyidi futhi emkhathini, futhi kulula. I last bezinto ezimbili yasezulwini acace eziphathekayo (siqala kwakuthiwa endabeni le nguzunga) kanye Meteor - ziyavutha ezivela doti omlilo isikhala.

lezinkanyezi ezinomsila

Akukho mgwamanda awangaphansi yasezulwini, ungakwazi ukujabulela ingqapheli eliwumhlaba, kuyinto inkanyezi enomsila. I lezinkanyezi ezinomsila ezahlukene kanye emkhathini kusuka asteroyidi?

Igama elithi "inkanyezi enomsila" njengoba umsuka yamaGreki asendulo futhi ngokwezwi nezwi lisho "enoboya", "shaggy". Comet sifike kusukela yangaphandle sonozungezilanga futhi, ngokufanelekile, babe yenziwe ngohlobo oluhlukile kuka asteroyidi kwakhiwa eduze kwelanga.

Ngaphandle umehluko ukwakheka, kunomehluko sobala ngaphezulu isakhiwo lezi zindikimba zasemkhathini. Comet esondela ilanga, ngokungafani elisemkhathini libonisa ikhoma futhi nenkungu igobolondo umsila, ehlanganisa igesi nothuli. Volatiles enomsila njengoba Ukushisa ngenkuthalo egqanyisiwe futhi vaporize, waliguqula ku lekhethelo elikhanyayo liyindikimba yasezulwini.

Ngaphezu kwalokho, asteroyidi lihamba omise, futhi ukunyakaza kwabo emkhathini ufana ukunyakaza abushelelezi futhi elinganisiwe amaplanethi abavamile. Ngokungafani asteroyidi, inkanyezi enomsila kakhulu ngaphezulu ukunyakaza kwabo. orbit kakhulu side. Comet eduze osondela Sun, ke asuka yona amabanga amade uma liya.

Inkanyezi enomsila ahlukene meteorite ukuthi siyahamba. Meteorite efanayo - kuwumphumela ukungqubuzana ka nendikimba ethile esemkhathini komhlaba.

Izwe wasezulwini nezwe yasemhlabeni

Mangisho ukuthi ukubukela esibhakabhakeni ebusuku isibili uyajabula lapho izakhamuzi zakhe ekuseni ujwayelene futhi kuyaqondakala. Futhi ngijabula kakhulu ukutshela interlocutor yakhe mayelana nezwe izinkanyezi izenzakalo engavamile emkhathini!

Futhi akusiwona ngisho umbuzo umehluko phakathi netshe elisemkhathini we kwemvula yezinkanyezi ezinomsila, futhi nokuqaphela ubuhlobo obuseduze kanye nokuxhumana ezijulile phakathi lasemhlabeni cosmic, okuyinto edingekayo ukusungula njengoba ngenkuthalo njengomdala phakathi kwendoda eyodwa kwenye.
