Indlela ukufumanisa i-Sun - yinto iplanethi okanye inkwenkwezi?

Abantu abaninzi bakholelwa ukuba ilanga iplanethi. Le ukungaqondi mhlawumbi kungenxa yobukhulu enkulu nto.

Overview

Sun - ilanga. Around kuye ezigxile ezinye izinto nkqubo. Ngenxa umsebenzi solar, zixhaswa eziphilayo emhlabeni, umiselwa kwemozulu. Ilanga - i nkwenkwezi yakudala. Kulindeleke ukuba kwiminyaka emine ukuya billion amahlanu eyadlulayo, ingxilimbela nebula gas-uthuli kwasekwa emajukujukwini. Kuye kwasekwa eLangeni kunye nezinye iiplanethi le nkqubo. Noko ke, wendele ukukhanya inkoliso ubunzima. Ukukhanya kufikwa Earth ngemizuzu nje esibhozo.

isakhiwo yangaphakathi

Ukuqonda Sun - inkwenkwezi okanye umhlaba unako, ingqalelo isakhiwo nkwenkwezi. Kukho iimpawu eziliqela yeyiphi into eyahlukileyo kwabanye. Ilanga kunye nezinye iinkwenkwezi zeebhola omkhulu ngokubanzi yigesi. Ayekholelwa ngokwabo ngenxa imikhosi womxhuzulane.

Umbindi isakhiwo lwangaphakathi kwelanga yindlela amile ngayo ngumongo. Apha, ukuguqulwa eyenziwa kwindawo helium hydrogen. Ngexesha ngeeatom kwenzeka xa kuphuma amandla, nto leyo iboniswa kwiindawo spectrum elanga ebonakalayo. Kumgama omalunga 0.2 ukuya 0.7 kwirediyasi yento ibekwe ngasentla kummandla engundoqo transfer radiative. Apha, amandla shintsho lwenzeka kukhethwa ngokusebenzisa nokufunxwa kunye ukuphuma ziluhlaza.

Ummandla පිළිතුරු iimpendulo, le nkqubo lwenziwa yi umbandela, ngenxa ngongqameko Ukupholisa ngokukhawuleza ibekwe phezulu. Kwenzeka ntoni efana abilayo engamanzi, leyo itshiswa ukusuka ngezantsi. maleko ebonakalayo zibizwa ngokuba "umoya". ngokuyinxenye radiation efikelela ngqo-mkhanyo.

Le umphezulu into

Stars, ngokuchaseneyo iiplanethi, ubuchule nokuvelisa ukukhanya. Lo maleko eyenza isakhiwo ezi zinto, abasabela esihambelanayo zenzeke. Ngeempawu kweemaleko, kunokwenzeka ukuba uphendule lo mbuzo: "Ilanga - yinto iplanethi okanye inkwenkwezi?"

A umphezulu Ukukhanya photosphere - umaleko ukukhanya-esikhupha. balo babulingana nesandla - ukusuka km ezilikhulu ukuya engamakhulu amane. Njengoko sisiya ekupheleni kumphandle ubushushu lifinyele ukususela 6600 ukuya 4400 K. Sun iqokobhe zangaphandle chromosphere. balo babulingana nesandla -. 2 amawaka Km. Imvelaphi yegama kwale maleko lu dityanisiwe ngombala obomvu. Ekubeni chromosphere ukuphakama lobushushu kunyuka ukusuka-4 ukuya ku-20 tysyach Kelvin.

Crown ke lokugqibela yeqokobhe kwelanga. Ngokomthetho liphethe kwentaba ehlokomayo prominences. Okokuqala uze kubanike amakhulu amawaka, kwaye kwezinye iimeko, kumgama ngaphezu kwesigidi kweekhilomitha. Ngenxa yoko, umoya elanga senziwa isithuba. Iqondo lobushushu umndilili corona isusela ukusuka ku-1 ukuya 2 Mill. K. Kwiindawo ezithile ngayo ukufikelela ukuya amabini ezigidi. Noko ke, nangona eli lobushushu okwandileyo, isithsaba ingabonwa kuphela ngexesha umnyama. ukukhanya kakhulu umaleko ephantsi-mninzi kubangelwa impahla yayo.

iimpawu

Uphononongo lwe Sun, izazinzulu ababandakanyekayo kunye maxesha amandulo. Uphando kuyaqhubeka unanamhla. Noko ke, izazinzulu bezisoloko akukho mbuzo: "Ilanga - yinto iplanethi okanye inkwenkwezi?"

Ekupheleni banesifo ze yamachiza kwinkulungwane yama-20 Hans Bethe uye wacebisa ukuba njengomthombo ukukhanya wamandla kunye nezinye izinto ezifana na indlela yenyukliya yokuqaphela. Bona kwenzeka ngaphakathi zeenkwenkwezi. Kwiqondo apho izigidi izidanga ukuba kuhlelwe nuclei helium of nuclei hydrogen.

Sun - inkwenkwezi ekhuthele kakhulu. Ngexesha kwelanga, uyakwazi ukubona ziintlantsi kunye prominences - ukukhutshwa kwezinto ezahlukeneyo ngobukhulu. Flash kwisiqalo yezinye kumphezulu kungabonwa ngoncedo nezixhobo ezizodwa. lobushushu yabo ingaphezulu ubushushu avareji komhlaba. Livela ukubaneka izazinzulu ezinxulumene igqwethwe (Izitenxo) lo mhlaba otsalayo.

umlambo insimbi

Ukuphendula umbuzo malunga ilanga - yinto iplanethi okanye inkwenkwezi, siya kuthi ngakumbi na umsinga amasuntswana insimbi evela kumphezulu olungaphandle isithsaba. Ngokomthetho liphethe amasuntswana alpha, electron kunye protons. Ehanjisiweyo "umoya solar" kunye ukuhla kancinane mninzi.

Yahlula ukuhamba ibe amacandelo amabini: ecothayo fast. I wokuqala ngesantya malunga 400 km / s kunye lobushushu 106 K. 1,4-1,6 • Ukwakhiwa olucothayo kufutshane umoya nolo isithsaba. flow okukhawulezileyo uba lobushushu 105 K • 8 isantya 750 km / s. ukwakheka balo likufutshane kweziyobisi photosphere. umoya Fast elanga rhoqo ngaphezu kade. Le yokugqibela luphawulwa kabini lexinene. Xa umlambo olucothayo kakhulu insimbi isakhiwo anzima ngakumbi kunobo lulophu ukuzila elanga. Ukongeza, iqulethe kwimimandla-gingxi.
