Kwemizimba yasezulwini ekuthiwa iiplanethi kwenkqubo solar?

Ukusuka kudaladala, abantu babebukele isibhakabhaka ebusuku waza waphawula ukuba ukongeza izinto zokubhala, kukho abo ukutshintsha indawo efanelekileyo lwabo kwabanye. Ngokuqhelekileyo sisithi oko iinkwenkwezi, kodwa ngaba? Zeziphi imizimba yasezulwini ibizwa ngokuba iiplanethi, yaye yintoni nkqubo kufuneka babe into ukuze oko kubizwa ngokuba iplanethi? Nguwuphi na kubo ziyinxalenye yenkqubo solar?

Planet. Inkcazo kunye neempawu

Nayiphi into into ayikhuphi ukukhanya, ubushushu kugqithisela ubukhulu a meters embalwa, yiplanethi ( "ebhadula" - liguqulelwe kwisiGrike). Kwisiqingatha sesibini senkulungwane lokugqibela ngcembe kungenisa iinkcazelo ngqo ngakumbi, kwaye ukuza kuthi ga ngoku, ukuze umzimba yasezulwini uvumile umhlaba, kufuneka ihlangabezane iimeko ezine ilandelayo:

• Le into akufuneki ibe inkwenkwezi.

• amanqaku ezikufuphi komzila musa ukususa ezinye imizimba enkulu yasezulwini.

• I into kufuneka imilo kufutshane ukulenza.

• I into kufuneka uphendule, ngeenxa zonke inkwenkwezi.

Langa neenkwenkwezi. Yintoni umahluko?

Umbuzo into ekuthiwa iiplanethi imizimba yasezulwini, siyakuqonda, kodwa yintoni umahluko yabo iinkwenkwezi? Planet phantsi amandla womxhuzulane yayo uyakwazi ukuthatha imilo ngeenxa kwaye ezixineneyo. Kodwa lo ubunzima akwanelanga ukuba ukuqala reactions fusion ngaphakathi emzimbeni. Star kwakhona umzimba ongowemvelo yasezulwini, ezinako ukubaleka yenyukliya reaction helium, hydrogen kunye nezinye iigesi, le nto ndiyibhalayo apho, obaneleyo kungena isithuba ngelixa isixa okukhulu amandla aguqulwe abe ukukhanya, ubushushu fluxes kagesi.

System Solar kwaye ifakiwe ngawo umhlaba

Ngokutsho amabango ezenzululwazi mihla, leyo ibizwa ngokuba "iastronomi", izijikelezi-langa kwenkqubo solar baqalisa ukwenza malunga 4.5 billion kwiminyaka eyadlulayo, ukuba isiphumo unamandla welo dubulo enye okanye eziliqela supernova ingxilimbela. Inkqubo solar ekuqaleni kwabakho ilifu igesi kunye amasuntswana nothuli eqalisiweyo intshukumo nangeendleko ubunzima disc yayo, iziko apho wazalwa inkwenkwezi entsha, nto leyo makwazeke kuni nonke kuthi njengoko ilanga.

Ngoko ke yintoni na imizimba yasezulwini ebizwa izijikelezi ngaphandle kwenkqubo nelanga? Kulo mbuzo impendulo ilula kakhulu; zonke izinto ube orbit zabo kwaye uphendule Afrika eqhelekileyo, iinkwenkwezi esembindini kunye neeplanethi ebizwa inkqubo elanga. Zahlula-hlulwe ngamaqela amabini amancinci izifundo ezine nganye:

• planethi ezisentlabathini - Mars, Venus ne Mercury. Bonke babe kwindawo Etsolweni lengxondorha, ubungakanani encinane, lo gama mgama kufutshane elangeni ngaphezu kwabanye.

• planethi - kwabanye, likaSaturn, uJupiter Uranus. Ezinkulu, ezibandakanya becala neplanethi nerhasi uphawu kuphela ezo emakhonkcweni, apho ukusekwa ezininzi kuThixo kobutyobo enamatye kunye ice uthuli.

Kude kube Agasti 25, 2006, kwakucingwa ukuba ukwakhiwa kwenkqubo solar kukho iiplanethi asithoba. Kodwa emva kokuba ukucacisa iinkcazelo apho kwagqitywa ukuba kunokwenzeka emhlabeni yesayensi kubiza iplanethi, iPluto, ngaphambili yinxalenye yenkqubo elanga njengoko yesithoba, into ezisemaphandleni ocande kudidi nenomlanga.

Yintoni isizathu sokuba sigqibo? Le nto ukuba ukuphuculwa ngeeteleskopu kunye nezinye izixhobo ngeenkwenkwezi, izazinzulu baye bafumanisa kufano iimpawu ku iPluto, izinto ezingcwele, inani leyo eza kwandisa kunye nexesha. Ukwenzela ukuthintela ukubhidana kwezinto okunokwenzeka kwixesha elizayo yaye yaqaliswa iimfuno ngqo ngakumbi ukuba imizimba yasezulwini, ebizwa langa.

isiphelo

Uphononongo-langa neenkwenkwezi ziya kuqhubeka ixesha elide kakhulu, yaye akukho namnye uzaziyo iimfihlelo ezininzi kuzimela ngokwabo kwisithuba esibonelelweyo zingaphi. Kwaye uya kuhlala iminyaka emininzi umbuzo njani ubomi kunjalo baqala iplanethi yethu kwinkqubo solar, kwaye ngokubanzi kuyo yonke iphela.
