Abantu abathanda i-cosmos kusukela ekuqaleni mhlawumbe baye bazibuza ukuthi ilanga liyiplanethi, inkanyezi noma isathelayithi. Ngokufanayo, iLanga lihlukaniswe ngezindlela eziningi futhi lihileleke ukuthi liyisathelayithi noma iplanethi. Nokho, lokhu kwakungeke kube ngaphezu kweqiniso. I Sol iyinkanyezi, ngoba ikhanya ngokukhanya kwayo.
Ilanga liyiplanethi, inkanyezi noma isathelayithi
Iyinkanyezi ebaluleke kakhulu kumuntu, futhi ngokwayo, zonke izinhlobo zezinto eziphilayo emhlabeni wethu, ngokuba yiyona yodwa ngaphakathi Uhlelo lomkhathi ngekhono lokudala amandla nokukhanya ngokwakho, okudingeka ngokungenakulungiseka ukuze impilo iqhubeke emhlabeni. Ukuze uqonde kangcono ukubaluleka kweLanga, ungafunda kabanzi mayelana ILanga liluhlobo luni lwenkanyezi?.
ILanga, lizwakalisa inqwaba yamandla nokukhanya ngokwalo, liyinhlangano enkulu kunazo zonke eSolar System. Ibeka usuku, ubusuku nezinkathi zonyaka, futhi ngisho nezinsuku zezinsuku zenzeke ngenxa yalo. Ngokunjalo, ngenxa yomthamo wayo omkhulu, ingagcina amaplanethi angaphezu kuka-8, umhlaba omncane, emzileni, iziphuphutheki kanye nabanye.
Ngokufanayo, ngokunikeza ukukhanya namandla, iLanga likhuthaza izitshalo ukuba zikhiqize umoya-mpilo, obalulekile ukuze abantu nezilwane zihlalisane, ngokusebenzisa i-photosynthesis, ukuguqula amandla elanga abe amandla amakhemikhali. Ukuze uhlole kabanzi ngale nqubo, vakashela isihloko sethu ku ukuthi iLanga lenziwe ngani.
ukwakheka kwelanga
Isiphendulwe kakade uma ilanga liyiplanethi, inkanyezi noma i-satellite, manje sizochaza indlela ilanga eladalwa ngayo, ngokusho kobufakazi bochwepheshe, cishe eminyakeni eyizigidi ezingu-4600 ngemva kokuwa. amandla adonsela phansi yendaba ngaphakathi kwendawo yefu elikhulu lamangqamuzana.
Iningi lale ngxenye linqwabelene lapho kugxilwe khona, kwathi enye yayisicaba yaba yiringi ku i-orbit lokho kwashintshwa esimisweni sonozungezilanga. Isisindo esimaphakathi saya ngokuya sijiya futhi savutha, sagcina sesivumela ukuqhuma kokuqala kokuhlangana kwe-nuclear eksisi yayo. Kukholakala ukuthi cishe zonke izinkanyezi zakhiwe ngenxa yalesi sizathu. Funda kabanzi mayelana nale nqubo esihlokweni sethu esithi izinhlobo zezinkanyezi.
ILanga cishe lineminyaka ephakathi futhi alikashintshi kakhulu iminyaka engaphezu kwezigidi eziyizinkulungwane ezine, futhi lizohlala liqine ngokwanele eminye iminyaka eyizigidi eziyizinkulungwane ezinhlanu. Nokho, ngemva kokuncibilika kwe-hydrogen kuyo umnyombo imile, iLanga lizoba nezinguquko eziqinile futhi libe bomvu kakhulu. Kuyabonakala ukuthi iLanga lizokhula ngokwanele ukuba ligwinye izindlela ezikhona manje zeMercury, Venus futhi mhlawumbe noMhlaba. Umhlaba.
ilanga a inkanyezi etholakala esiteji esinqunyelwe ukuqhubeka okuyinhloko, enohlobo olumnyama lwe-G2 nohlobo olucwebezelayo V, ngakho-ke, ngendlela efanayo ebizwa ngokuthi i-yellow dwarf, yadalwa phakathi kweminyaka eyizigidi ezingu-4567,9 kanye ne-4570,1 futhi izohlala ngokulandelana kokuqala. eminyakeni engaba yizigidi ezingu-5.000 kamuva.
Naphezu kokuba inkanyezi emaphakathi, iyona kuphela ukumelwa kwayo okungalinganiselwa ngeso lenyama, nge-engeli yedome engu-32′ 35″ ku-perihelion kanye no-31′ 31″ e-aphelion, enikeza i-radius eyisilinganiso esingu-32′ 03″ . Inhlanganisela yobukhulu kanye nemizila yeLanga kanye ne Luna Zinjalo kangangokuthi zibhekwa, cishe, ngevolumu efanayo esibhakabhakeni. Lokhu kufinyelela ububanzi obubanzi bokufiphala kwelanga (ingqikithi, i-annular noma ingxenye). Uma ufuna ukwazi okwengeziwe ngalezi zenzakalo, bheka isihloko sethu izihlambi zezinkanyezi.
Ngakolunye uhlangothi, umphumela omkhulu weLanga Emhlabeni uye waqashelwa kusukela ezikhathini ze-paleolithic futhi amasiko athile aye ahlonishwa njengeqhawe. Ukuhamba koMhlaba eduze neLanga kuyindawo yekhalenda yelanga, okuyi-almanaka esetshenziswa kakhulu namuhla.
ukwakheka kwelanga
El Sol Ihlanganiswe ngamanani ahlukahlukene kanye nezinhlobo zomhwamuko kanye nazo zonke izendlalelo zayo, ikakhulukazi nge-25% ye-helium, i-74% ye-Hydrogen kanti enye ithengiswa ngamaqembu angalingani esibabule, umoya-mpilo, i-magnesium, i-neon, i-nitrogen, i-silicon, phakathi kokunye. Ukuze ujule ezakhini eziyiqambayo, ungafunda ngakho kuzokwenzekani uma iLanga liphuma.
Le miphunga ishintshaniswa ezingxenyeni zeLanga eziqala ukusuka ku-aura, indawo eguquguqukayo, bese kuba i-chromosphere, i-photosphere, indawo yokuthekelisa exhumanisayo, indawo i-tachocline, ukunwetshwa kwezinto zokuthutha ezikhipha imisebe futhi ekugcineni kube i-eksisi, lapho kukhona isamba esikhulu samagesi, ikakhulukazi i-hydrogen ukuze kwenziwe ukusabela kokuhlangana kwe-nuclear ukuze kwakhiwe i-helium.
Iziphetho mayelana nokuthi ilanga liyiplanethi, inkanyezi noma isathelayithi
Ngaphambi kokuchaza ukuthi ilanga liyiplanethi, inkanyezi noma isiphuphutheki, kubalulekile ukuchaza lokhu kwakamuva. Isathelayithi yinto ephilayo yasezulwini ehlangene, ihlukaniswe njengezwe eliguqubele elihamba emzileni oseduze neplanethi ethile, okucatshangwa ukuthi ishayisana nomunye umzimba nenkanyezi okukhulunywa ngayo, izikhipha ku-astral cortex, njengoba kunjalo. icala leNyanga, noma zingaba amadwala, ama-meteorite noma izinkanyezi ezinomsila ezingena emzileni wendawo yonke bese zihluleka ukuhamba.
Ngalesi sizathu, amasathelayithi mancane kuneplanethi yokuqala, nokho, amanye anobukhulu obukhulu obungafinyelelwa ngisho nangendlela kanambambili. imizila, njengoba zingase zibhekwe njengamaplanethi amabili.
Ngalolu hlelo lwemibono, esivele sinesithombe esicacile sokuthi iLanga liyini nokuthi iyini isathelayithi, singabona kahle uma iLanga liyinkanyezi. satellite, futhi impendulo ingucha.
Kulula ukuqaphela ngemininingwane enikeziwe, ukuthi iLanga alihambisani nanoma iyiphi yalezo satellite enazo, njengoba ingeyona inkanyezi eguquguqukayo, ayincane kunamanye amaplanethi futhi vele ayizungezi ezinye. iplanethi, nokho sisondele kuyo.
Kulula ukuqagela, singazi kahle ukuthi iLanga limi kanjani, ukuthi ngokuzihlukanisa nomthamo ofanayo noweNyanga, ake sibuyekeze ukuthi iyisathelayithi, futhi abaningi baze bawuvikele lo mbono ngoba iLanga lizungeza eduze neNyanga. IMilky Way noma i-Galaxy of the Sun, noma kunjalo, ngisho nalokhu akusona isathelayithi, ngoba ukuze ihlolwe kanjalo, kufanele ijikeleze inkanyezi ethile.
Ngakho-ke, sesivele siyayazi impendulo yokuthi iLanga liyisathelayithi, kodwa manje kuza omunye umbuzo, ikakhulukazi ukuthi yini Sol Futhi sikuhlukanisa kanjani lokho?
I-Sun iwuchungechunge oluyinhloko inkanyezi yesigaba se-G, eyaziwa nangokuthi i-yellow dwarf noma i-yellow G-class dwarf, lokhu kufanekisa lokho uma kuqhathaniswa nezinye. izinkanyezi, iLanga lisenobukhulu obuncane kakhulu, nokho, lizokhula ngokuhamba kweminyaka, ngokuhlangana nokushintsha kwephimbo libe bomvu kakhulu. ILanga lingakwazi ukukhiqiza ukukhanya kwalo namandla, isici amasathelayithi angeke akwazi ukusiveza.
INkosi yethu iLanga ayihlukile ezinkanyezini esizibona esibhakabhakeni ubusuku nemini, ngokuvamile lapho kunenyanga entsha, futhi ekhanya futhi ibenyeze ubusuku bonke. Into ethatha indawo yayo yindlela atholakala kuyo iSolar System kanye nezinkanyezi, ikakhulukazi Umhlaba.
Okokugcina, uma sesazi ukuthi ilanga liyiplanethi, inkanyezi noma isathelayithi, singakwazi ukubona ukuthi elethu inkanyezi ibukeka inkulu esibhakabhakeni sethu, kuyilapho ezinye zibukeka zincane uma ziqhathaniswa. Mhlawumbe, kwenye iplanethi ezungeza lezo zinkanyezi, iLanga libukeka lifana ncamashi njengoba sihlukanisa ezinye, lobukhulu obufana kakhulu nendawo ekhanyayo.
