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 lokuzidalela amandla ngokwawo kanye nokukhanya, okudingeka ngokungenakulungiseka ukuze impilo iqhubeke emhlabeni.
ILanga liveza izindodla zamandla nokukhanya ngokwalo, futhi liyibhizinisi elikhulu kunawo wonke ku-Solar System. Ilungisa imini, ubusuku nezinkathi zonyaka, ngisho ngenxa yayo ama-solstices ayenzeka. Ngokunjalo, ngenxa yomthamo wayo omkhulu, ingagcina amaplanethi angaphezu kuka-8, imihlaba emincane, iziphuphutheki kanye nabanye.
Ngokufanayo, ngokunikeza ukukhanya namandla, iLanga likhuthaza izitshalo ukuba zikhiqize umoya-mpilo, okuyisibopho kubantu nasezilwaneni, ukuze zihlalisane, nge-photosynthesis, ziguqule amandla elanga abe amandla amakhemikhali.
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 eyashintshwa esimisweni sonozungezilanga. I-centric mass yakhula kakhulu futhi yashisa kakhulu, yagcina inikeze indawo yokuqala yokuhlangana kwe-nuclear ku-axis yayo. Kutholakala ukuthi cishe zonke izinkanyezi zakhiwe ngenxa yalesi sizathu.
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 ngomthamo ofanayo ocatshangwayo esibhakabhakeni. Lokhu kufinyelela esikalini esikhulu sokufiphala kwelanga okuhlukene (ingqikithi, i-annular noma ingxenye).
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 nezigaba zomhwamuko kanye nazo zonke izendlalelo zayo, ikakhulukazi nge-25% ye-helium, i-74% ye-hydrogen futhi enye ithengiswa ngamasethi angalingani esibabule, i-oxygen, i-magnesium, i-neon, i-nitrogen, i-silicon, phakathi kokunye.
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.
Kulolu hlelo lwemibono, esivele sinesithombe esicacile sokuthi iLanga liyini nokuthi liyini isathelayithi, singabona kahle uma iLanga liyi-satellite. 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 thina uma sisondele kuso.
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 liyi-satellite, kodwa manje kuphakama omunye umbuzo, ikakhulukazi ukuthi 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 phakathi neminyaka, ngokuhlangana nokushintsha kwe-hue libe bomvu kakhulu. ILanga lingazibangela ukukhanya kwalo, namandla ngokwalo, okuyisici amasathelayithi angakwazi ukuwenza.
Inkanyezi yethu iNkosi, ayinakho ukuphambana nezinkanyezi ngalobo busuku nobusuku esikubona esibhakabhakeni, imvamisa lapho kuba nenyanga entsha, futhi ezikhanya futhi zibenyeze ekuseni yonke. Into ethatha indawo yayo umzila atholakala kuwo ku-Solar 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.
