Yintoni Meteor? Meteora: photo. Asteroids, ezinomsila, eziwa, awe

Asteroids, ezinomsila, eziwa, awe - izinto ngeenkwenkwezi ukuba kubonakala ukuba okufanayo uninitiated kwi eziseko nenzululwazi imizimba yasezulwini. Enyanisweni ke bahluka ngeendlela ezininzi. Izinto zobumnini ezenzeka izijikelezi-langa ezincinane, ezinomsila, eziwa, awe, khumbula nje ngokwaneleyo. Kwakhona zifana ezithile: izinto kunjeya zichongwe imizimba ezincinane, ngokufuthi ezithathwa nje eziwa emajukujukwini. Eso Meteor, eyahluke ngayo Ibhanti okanye enomsila, ziziphi iimpawu zabo kunye nemvelaphi, kwaye kuya kuxoxwa ngezantsi.

ngabelusi tailed

Ezinomsila - izinto space, ebandakanya ngeegesi kunye namatye zibambene. Zisekelwe kwiingingqi ezikude kwinkqubo elanga. Abaphengululi baye bacebisa ukuba mithombo iphambili ezinomsila - na oqhagamshelwano phakathi Kuiper ibhanti kunye disc saa, kwaye ezikhoyo ngombandela ilifu Oort.

Ezinomsila zijikeleza evuthelweyo kakhulu. Ekusondeleni ukuya Sun, bakha isiqaqa nomsila. Ezi zinto ziquka kwezinto aziphethe sukube (umphunga wamanzi, ammonia, methane), uthuli namatye. Intloko enomsila noma isiqaqa, - i Iqokobhe amasuntswana ngomzuzu, apho ukukhanya nokubonakala. It has a imilo ungqukuva yaye ifikelela ubukhulu bayo ubuninzi kwi indlela ukuya ilanga phezu kumgama 1.5-2 unit ngeenkwenkwezi.

Xa phambi coma ngumongo enomsila kuthiwa ibekwe. It idla ubungakanani omncinane kunye side. Kude kakhulu ukusuka undoqo kwelanga - oko kukuthi zonke egqithiseleyo enomsila. Liphethe ngeegesi kunye namatye zibambene.

iintlobo nethala

Ulwahlulo ezi imizimba yasezulwini wabeka rhoqo kwabo unyango ehlabathini lonke. Ezinomsila ukubhabha emhlabeni kweLanga kwiminyaka engaphantsi kwama-200 ubudala, zibizwa ngokuba mfutshane-xesha. Amaninzi, baya kuwa kwimimandla yangaphakathi inkqubo iiplanethi ukusuka ibhanti Kuiper okanye saa idiskhi. Long-ithuba ezinomsila babuyelayo kwixesha kwiminyaka engaphezu kwama-200. "Iphandle" Lwabo - ilifu Oort.

"Small Planet"

Asteroids luqulathe oluqinile. Ngobukhulu ukuba izijikelezi-langa ngaphantsi kakhulu, nangona amanye amalungu zezi zinto isithuba babe satellites. Uninzi iiplanethi ezincinane, njengoko zazibizwa ngaphambili, buzinze engundoqo ibhanti ke, ilitye, ephakathi umzila iMars Jupiter.

Inani elipheleleyo imizimba enjalo yasezulwini, eyaziwa ngokuba 2015 kwagqithiswa 670.000. Nangona inani onocwangco ngolu hlobo, igalelo lalowo izijikelezi kwi ubunzima zonke izinto kule nkqubo solar ayinamsebenzi - kuphela 3-3.6 x 10 ²¹ kg. Kuyinto%-4 kuphela ye parameter efanayo eNyangeni.

Ukubandakanya izijikelezi-langa ezincinane, asingabo bonke umzimba encinane. Umbandela yokukhetha ke ubukhulu. Ukuba udlula-30 m, injongosenzi uthathwa ukuba Ibhanti. Umzimba ne imilinganiselo emincinane kuthiwa avela.

ngezigaba izijikelezi

Isiseko liQela eliCebisayo yezi imizimba yasezulwini nto ezimbalwa parameters. Asteroids iimpawu idibene ezindleleni zazo kunye spectrum yokukhanya ebonakalayo yabonakala ukusuka kumphezulu zabo.

Ngokutsho kwiimpawu yesibini iiklasi ezintathu eziphambili:

• carbon (C);
• silicate (S);
• metal (M).

Udidi lokuqala luquka nama-75% kuzo zonke izijikelezi-langa ezincinane ezaziwayo namhlanje. Kunye nokuphuculwa kwezixhobo kunye Bole nzulu bezinto ezinjalo zokuhlela uyakhula.

emkhathini

Meteoroid - olunye uhlobo imizimba yesiqalo. Asiyiyo izijikelezi-langa ezincinane, ezinomsila, eziwa okanye awe esibhakabhakeni. Le peculiarity ezi zinto - ubukhulu encinane. Avela kwi imilinganiselo zibekwe phakathi izijikelezi kunye nothuli emajukujukwini. Ngenxa yoko, ukuba ithwalwe umzimba enobubanzi engaphantsi kwe-30 m. Ezinye izazinzulu sele uqinisekile ukuba meteoroid njengequmrhu ngesandla ububanzi of 100 m ukuya kwi-10 m. Ngokutsho imvelaphi yazo, ukuba lokuqala okanye ezenqanaba lesibini, ezikhandelwa emva kokuba kutshatyalaliswe izinto ezinkulu.

Athe engena umoya meteoroid umhlaba uba. Kwaye apha sele esondela impendulo yombuzo, yintoni a Meteor.

sokudubula star

Maxa wambi iinkwenkwezi kwelihlo esibhakabhakeni ebusuku omnye ngequbuliso uyajika, ichaza arc encinane ekho. Ngubani na okhe wabona izinto ezinjalo, uyazi yintoni a Meteor. Oku "ziinkwenkwezi ezibinzayo" nongenawo buhlobo iinkwenkwezi ngokwenene. Meteor - phenomenon phantse esesibhakabhakeni eyenzeka xa umoya engena iqokobhe iplanethi yethu ezincinane izinto ubungakanani (ezo avela). Aqaqambileyo bokugcinwa le flash kuxhomekeke kubungakanani umzimba original yesiqalo. Ukuba Meteor kukhanye ngaphezu sesihlanu ubukhulu, ibizwa ngokuba fireball.

ukubukela

La nga bahlonelwe kuphela langa zibe umoya. Emkhathini kwi Moon okanye Mercury ngeke babonwe kuba kuswela ingxowa yomoya.

Ukuba 'iinkwenkwezi eziwayo "iimeko ezifanelekileyo kunokubonwa yonke ebusuku. Kungcono ukonwabela eziwa ngemini elungileyo kwaye kude kakhulu ukusuka kumthombo ngaphezulu okanye enamandla ngaphantsi yokukhanya zedolophu. Kwakhona esibhakabhakeni kufuneka inyanga. Kulo mzekelo, oku kungabonakala ngeliso lenyama phantsi 5 ngeyure nganye. Izinto, ekhokelela imbonakalo single "Ukuwa Iinkwenkwezi" zisenokusekelwa kwelanga ezahlukeneyo wezijikelezi. Ngoko ke, indawo kunye nexesha ukuvela kwazo esibhakabhakeni ayikwazi ukuqikelelwa ngokuchanekileyo.

imifula

Meteora, iifoto apho nazo thaca kweli nqaku, njengoko umthetho, abe imvelaphi into eyahlukileyo. Bayinxalenye omnye izibawu ezininzi lwemizimba ezincinane yasezulwini olujikelezayo ehlabathini lonke kukho indlela ethile. Kwimeko yabo, ixesha elifanelekileyo ukulungiselela-up (ixesha, ekhangele esibhakabhakeni, nabani na ngokukhawuleza ukuqonda ukuba yintoni Meteor) uchazwa kahle.

Roy ezi zinto indawo ubizwa ngokuba ishawa Meteor. Kwiimeko ezininzi, ukuba akhiwa ekutshatyalalisweni ngumongo enomsila. imijelo yamasuntswana ngamnye ezihambayo ngaxeshanye omnye komnye. Noko ke, phezu komhlaba kubonakala ukuba ophuma kwindawo ethile encinane esibhakabhakeni. Le nxalenye kuthiwa ukubhobhoza unyulu. Igama ninyakazele Meteor, njengoko umthetho, banikwe lekroza apho ngumbindi obonakalayo (unyulu) okanye igama enomsila, kwawa nto leyo eyakhokelela ekubeni imbonakalo yakhe.

Meteora, leyo kulula ukufumana ifoto kunye iintsimbi ezikhethekileyo zinxulumene nokuphuma ezinkulu ezifana Perseids, Quadrantids le -Aquarids, Lyrids, i Geminids. Iyonke ukuza kuthi ga ngoku, ykuba ubukho kwimisinga 64 yaye malunga 300 zilindele engqinisekweni.

amatye zasezulwini

Ayevela, izijikelezi-langa ezincinane, eziwa kunye nethala - ezinxulumene ngendlela enye okanye omnye ingqikelelo zokugweba. Eyokuqala into isithuba owawa eMhlabeni. Kakhulu, bona umthombo izijikelezi-langa ezincinane, ubuncinane - enomsila. Ayevela idatha nanto kumalungu ezahlukeneyo kwinkqubo elanga ngaphaya Earth.

Uninzi kula maqumrhu ziwele kwiplanethi yethu, ukuba abe ubungakanani elincinane kakhulu. Eziphawulekayo bangadluli dimensions awe yayo ashiye ngasemva imizila mpembelelo, oko buqapheleke yaye emva kwizigidi zeminyaka eyadlulayo. yaziwa kakuhle umngxuma kufutshane nedolophu Winslow, Arizona. Kokuwa zimpahla ngo-1908, kuthiwa wabangela isiganeko Tunguska.

izinto ezinkulu ezifana "tyelela" Umhlaba zonke embalwa kweminyaka million. ayevela abaninzi bafumana ezi kunokuba nokuthozama ubukhulu, kodwa ube ngaphantsi esibalulekileyo kweyobunzululwazi.

Ngokutsho izazinzulu, ezi zinto na onokumxelela lukhulu ngexesha lokusekwa kwenkqubo elanga. Wavele, ukuba ngamasuntswana zenkqunto owenza loo mhlaba abatsha. Amanye ayevela ukufika kuthi evela Mars okanye inyanga. abathululi ezinjalo yesiqalo ukuvumela ukuba bafunde izinto ezintsha malunga izinto ezikufuphi ngaphandle iindleko elikhulu matutu ezikude.

Ukuze ngentloko umahluko ezichazwe kweli nqaku liphindaphindwe izinto ukuze anikele inguqu lwemizimba esithubeni. Lo ke, ilitye, equka amatye ngamatye nzima okanye enomsila, nto leyo ibhloko ngumkhenkce, intshabalalo ukujikelezisa avela ukuba reentry iplanethi umsi Meteor, zivutha, okanye bawe, yalitshintsha awe esibhakabhakeni. Zakutshanje kuphucula ulwazi lwethu zonke engaphambili.

Ayevela, ezinomsila, eziwa, kunye izijikelezi kunye avela - nxaxheba rhoqo izithuthi isithuba. Isifundo kwezi zinto kuzisa igalelo elikhulu kwindlela ebesikade siqonda ngayo indalo. Kunye nokuphuculwa izixhobo Astrophysics ufumane inkcazelo engakumbi malunga nezi zinto. Kugqitywe kutshanje, "Rosetta" mission probe wabonisa ngokucacileyo njani inkcazelo eninzi zingafumaneka yi isifundo eneenkcukacha zezi imizimba yesiqalo.
