Ubume yenkqubo elanga

Izazinzulu zikholelwa ukuba ukuyilwa kwenkqubo solar malunga billion kwiminyaka emihlanu edlulileyo. Ngokutsho ibhanile thiyori ekhoyo Umhlaba-langa eziyingqongileyo kwasekwa kummandla uthuli cosmic iLanga. Ngokutsho imibono, amasuntswana uthuli zenziwa nickel nentsimbi atom, kwakunye silicates. Baye phantsi amafu nothuli langoku kufutshane iigesi leyo ibe carbon ulungelelwaniso. Kamva, kwakukho iikhompawundi nitrogen kunye hydrocarbon.

Ubume yenkqubo solar: hypothesis

Eyaziwa hypothesis ye ukuvela kwisixokelelwano sethu langa ingcamango magnetic, leyo usekwe kwingcinga yokuba izazinzulu ukuba ilanga kanye baba olunzulu Imagnethi intsimi kunye sokukhanya okukufutshane nebula ubunjwe athom neutrally ityala. Ngenxa yoko, imitha kunye ionization yangqubana yenzekile ngamasuntswana awela kumgibe imigca otsalayo inguwo emva inkwenkwezi. Emva baqala kweminyaka emininzi kwelanga ukuphulukana le torque ngokugqithisa ilifu kwegesi, leyo kwasekwa le planethi.

Noko ke, le mfundiso kwenzeke. Enyanisweni, i-atom izinto ukukhanya zaye insimbi kufutshane ilanga, kunye nesinyithi enzima - on. Yaye umphumo uya kuba ukuba inkwenkwezi elikufutshane umhlaba kwakuza kufuneka wakhiwe izinto kunenye chemical - hydrogen kunye helium, kunye kude - nickel kunye nesinyithi. Noko ke, namhlanje sibona umfanekiso esahlukileyo.

Ukuze bahlukane ephikisanayo, Cingela omtsha sele lusekiwe, ebonisa ukuba ilanga seliya ukwenza kwi enzulwini fu. Of ezijikelezayo ngokukhawuleza kakhulu, yaye ngokuthe ngcembe lo nebula baba ngakumbi kwaye iflethi ngakumbi de yaba diski. Emva kwexesha elithile, uye wazuza ukukhawulezisa kunye Sun - phezu koko, baye uyekile ukusebenza. Emva koko, lo disk lafika iinkqubo, nto leyo ekhokelele ekuqaleni lokusekwa kwenkqubo elanga.

Eyaziwa Cingela ngemvelaphi iiplanethi na ingcamango ukuvela kwenkqubo solar ukusuka igesi kunye namafu nothuli nengqele olubiyele ilanga.

Ubume kwenkqubo elanga: iiplanethi

Namhlanje, kukholelwa ukuba System Solar ibandakanya ilanga neenkwenkwezi langa ezisibhozo. Ngokutsho iimpawu ezibonakalayo bezinto zasezulwini zinakho ihlelwa iintlobo ezimbini. Elinye iqela ibandakanya Umhlaba-langa ezo zifana naye - Mars, Venus, Mercury. Elesibini iquka planets ezinjalo Esikhulu Solar System nguNeptune, Uranus, likaSaturn, Jupiter.

Ukwahlulwa iiplanethi ezenziwe iimpawu ezintathu: ubunzima, mninzi kunye nobukhulu. I-avareji lexinene-langa akwi eziyintlabathi, ngaphezu izihlandlo ezihlanu ngaphezu inani elifanayo iiplanethi ezinkulu. Ubume yenkqubo solar lubonisa ukuba ecaleni ilanga izinto eziphila iqanjwa oxides, kunye khompawundi elinzima imichiza: aluminiyam, nemagnesium, intsimbi, lesilicon, kwaye non-zesinyithi. Edreyi konga eliphantsi ngenxa ubume babo. Bona zikwimeko elulwelo okanye sukube, yaye hydrogen isambuku okanye helium.

Nangona kunjalo, ubume inkqubo elanga lubonisa ukuba naziphi na ezinye iiplanethi ezinkulu ngokomthamo awazo zonke izinto ezidibeneyo yasezulwini kukodwa. Zonke Edreyi ziye eyandisiweyo umoya onamandla eliquka hydrogen lwalusanda, yaye equlathe ammonia, methane, helium, kunye namanzi. Ezi izinto ezisele Akukho ekhulwini ngaphezu kwesinye ngemithwalo yabo. nokubunjwa kwayo planethi efanayo kwezinye iinkwenkwezi kwindawo yokuqala - ilanga.

hydrogen uwabonisa zinokudluliselwa ukusuka sukube kwifom engamanzi, nkqu okuqinileyo. Ucinezelo wathandwa elikhulu ngenxa ujikelezo ejikeleza esqwini.

Iiplanethi ezinkulu kufuneka ukuthwasa ezininzi: kaZeyus engaphezu kwama-60, Uranus - 27, uSaturn - 62, nguNeptune - 13, kwakunye namakhonkco Orbital, equka, yi vekeleke, izazinzulu ukusuka material-Hewana kutshatyalaliswa.

Kuba iiplanethi ezinkulu kukho into isithuba encinci - iPluto. Ke wavula ngo 1930 kwaye nangoku ayiqondwa kakuhle. De kwango-2006, kwakucingwa ukuba inkqubo yethu elanga iiplanethi ezilithoba, kwaye iPluto waye abokugqibela babo. Ngelo xesha langoku ukuba ibalwe phakathi yiplanethi encinane.
