Yini izindikimba zasezulwini ngokuthi amaplanethi yesimiso sonozungezilanga?

Kusukela esikhathini eside esidlule, abantu ababukile esibhakabhakeni ebusuku futhi ngaphawula ukuthi ngaphezu izinto umile, nanso are labo ushintshe indawo zawo ezilinganiselwe kwabanye. Ngokuvamile sithi kuba izinkanyezi, kodwa ingabe? Yikuphi zasemkhathini abizwa ngokuthi amaplanethi, futhi yini okufanele abe into ukuze lungase lubizwe ngokuthi iplanethi? Ngumuphi kubo ziyingxenye yesimiso sonozungezilanga?

Planet. Incazelo nezici

Iyiphi into okungahambisani ihlaba umkhosi ukukhanya, ukushisa kanye idlule ngobukhulu a amamitha ambalwa, iyona iplanethi ( "ezidukayo" - lihunyushwe kwelesiHeberu ngesiGreki). Engxenyeni kwekhulu elidlule yesibili kancane kancane ukwethula izincazelo eqonde kakhulu, futhi kuze kube manje, ukuze nendikimba ethile esemkhathini usevumile planethi, kumele ukwazi ukuhlangabezana izimo ezine ezilandelayo:

• Into akumele ibe inkanyezi.

• amaphuzu Eduze komzila wokuzungeza musa ukuthutha neminye imigwamanda enkulu yasezulwini.

• Into kumele kube ukuma eduze eyindilinga.

• Into kumele uphendukisa emhlabeni inkanyezi.

Amaplanethi nezinkanyezi. Uyini umehluko?

Umbuzo lokho izindikimba zasezulwini ngokuthi amaplanethi, siyaqonda, kodwa siyini umehluko zabo kusukela izinkanyezi? Planet ngaphansi amandla adonsela phansi yayo siqu uyakwazi ukuthatha round ukuma lunesibalo okusezingeni eliphezulu. Kodwa lokhu mass akwanele ukuqala Fusion ukusabela ngaphakathi emzimbeni. Inkanyezi futhi umzimba wemvelo yasezulwini, uyakwazi ukusebenzisa iArmagedoni yokusabela-helium, i-hydrogen nezinye amagesi, okuvela kulo yakhiwa, imbuthuma esikhaleni ngenkathi Kusaphazwa amandla ibe ukukhanya, ukufudumala kanye fluxes kagesi.

Solar System kanye azifaka kuwo iplanethi

Ngokusho yesimanje izimangalo isayensi, okuthiwa "astronomy", amaplanethi yesimiso sonozungezilanga waqala ukwakha eminyakeni engaba yizigidi eziyizinkulungwane 4.5 edlule, ekubeni umphumela onamandla kunayo ukuqhuma eyodwa noma ezimbalwa supernova giant. Uhlelo elanga ekuqaleni kwakukhona ifu igesi nge uthuli ukuthi kwakheka ukunyakaza futhi ngezithukuthuku disc yayo mass, maphakathi okuyinto wazalwa inkanyezi entsha, okuyinto sonke eyaziwa ngokuthi ilanga.

Ngakho lokho izindikimba zasezulwini ngokuthi amaplanethi ngaphandle komthala? On lo mbuzo impendulo silula: zonke izinto kufanele orbit zabo siqu futhi lapho uphendukisa azungeze ovamile, izinkanyezi emaphakathi namaplanethi ngokuthi zesimiso sonozungezilanga. Basuke ngamaqembu amabili elincane lezikhonzi ezine ngamunye:

• amaplanethi eliwumhlaba - Mars, Venus futhi Mercury. Bonke babe surface enamadwala kanye nosayizi esincane, kanti kude eduze kwelanga kunabanye.

• giant amaplanethi - Neptune, Saturn, i-Jupiter ne-Uranus. Elikhulu, ehlanganisa igesi ngokuyinhloko iplanethi nge isici kuphela lezi amasongo, okuyinto akhiwa a sebuningini doti enamadwala nothuli ice.

Kuze kube ngo-August 25, 2006 kukholakala ukuthi ukwakheka sonozungezilanga kukhona amaplanethi ayisishiyagalolunye. Kodwa ngemva hlandla izincazelo lapho kwanqunywa ukuthi kungenzeka emhlabeni yesayensi shayela iplanethi, Pluto, ngaphambili ingxenye isimiso sonozungezilanga eyesishiyagalolunye, into akude kakhulu lidlule ku isigaba yemifino.

Sasiyini isizathu leso sinqumo? Into wukuthi nge ngcono izibonakude kanye namanye amathuluzi yezinkanyezi, ososayensi baye bathola ezifuze izici ukuze Pluto, izinto ezingcwele, inani okuzokwenza ukwandisa nge sikhathi. Ukuze ugweme ukudideka kungenzeka esikhathini esizayo futhi kwangena nezimfuneko eqonde kakhulu kuwo izinto ezisemkhathini, ngokuthi amaplanethi.

isiphetho

Ucwaningo amaplanethi nezinkanyezi uzoqhubeka isikhathi eside kakhulu, futhi akukho muntu ongathi ukwazi ukuthi zingaki izimfihlakalo ngaphezulu ngicashe ngokwabo lesiniketiwe. Futhi sizohlala iminyaka eminingi umbuzo kanjani impilo namanje waqala eplanethini yethu esimisweni sonozungezilanga, futhi bebonke kuyo yonke indawo.
