Abantu abathanda i-cosmos kwasekuqaleni mhlawumbi baye bazibuza ukuba Ilanga yiplanethi, inkwenkwezi okanye isathelayithi . Ngokufanayo, iLanga liye lahlulwa ngeendlela ezininzi kwaye libandakanyeka malunga nokuba yisathelayithi okanye iplanethi. Nangona kunjalo, le nto ayinakuba ngaphezulu kunenyani. I Sol yinkwenkwezi, kuba yona ikhanya ngokukhanya kwayo.
Ilanga yiplanethi, inkwenkwezi okanye isathelayithi
Yeyona nkwenkwezi ibalulekileyo emntwini, kwaye ngokwayo, zonke iintlobo zobomi kwiplanethi yethu, ngokuba yiyo yodwa ngaphakathi kwiplanethi yethu. ISistema Solar ngokukwazi ukwenza amandla ngokwawo kunye nokukhanya, okuyimfuneko ngokungenakulungiseka kwinkqubela phambili yobomi emhlabeni.
ILanga livakalisa izixa ezikhulu zamandla kunye nokukhanya ngokwalo, kwaye lelona qumrhu likhulu kwiSolar System. Ilungisa imini, ubusuku kunye namaxesha oNyaka, nkqu nombulelo kuyo i-solstices iyenzeka. Ngokunjalo, ngenxa yomthamo wayo omkhulu, inokugcina iiplanethi ezingaphezulu kwe-8, umhlaba omncinci, i-satellite nabanye.
Ngendlela efanayo, ngokubonelela ngokukhanya kunye namandla, iLanga likhuthaza izityalo ukuba zivelise ioksijini, enyanzelekileyo kubantu nezilwanyana, ukuba zihlale kunye, nge-photosynthesis, ukuguqula amandla elanga kumandla emichiza.
ukubunjwa kwelanga
Sele siphendulwe ukuba ilanga liyiplanethi, inkwenkwezi okanye isathelayithi, ngoku siza kuchaza indlela ilanga eladalwa ngayo, ngokutsho kobungqina beengcali, malunga ne-4600 yezigidi zeminyaka emva kokuwa. Umxhuzulane yomcimbi phakathi kwendawo yelifu elikhulu lemolekyuli.
Uninzi lweli lungu lidityanisiwe kugxininiso, ngelixa elinye lacandwa laphuma kwiringi kwi umjikelezo eyatshintshwa kwisixokelelwano sezijikelezi-langa. Ubunzima becentric bukhula buba ngqindilili kwaye bushushu, ekugqibeleni bunike indawo yokuqala yokudibanisa kwenyukliya kwi-axis yayo. Kufunyaniswa ukuba phantse zonke iinkwenkwezi zenziwe ngulo nobangela.
ILanga limalunga nobudala obuphakathi kwaye alikatshintshi kakhulu iminyaka engaphezulu kwe-4.000 yeebhiliyoni, kwaye liya kuhlala liqinile ngokwaneleyo eminye iminyaka eyi-5.000 yeebhiliyoni. Nangona kunjalo, emva kokunyibilika kwe-hydrogen kuyo eyona nto iphambili imile, iLanga liya kutshintsha ngokungqongqo kwaye lijike libe bomvu kakhulu. Kuyabonakala ukuba iLanga liya kuba likhulu ngokwaneleyo ukuba liginye ii-orbits zangoku zeMercury, iVenus kunye mhlawumbi noMhlaba. Umhlaba.
ilanga ngu inkanyezi ebekwe kwinqanaba elichongiweyo lokuqhubekeka okuphambili, kunye nohlobo olumnyama lwe-G2 kunye nohlobo lwe-V, ngoko ke, ngendlela efanayo ebizwa ngokuba ngumthubi, yadalwa phakathi kwe-4567,9 kunye ne-4570,1 yezigidi zeminyaka kwaye iya kuhlala kulandelelwano lwangaphambili. malunga neminyaka engama-5.000 yezigidi kamva.
Ngaphandle kokuba yinkwenkwezi ephakathi, yiyo yodwa ukumelwa kwayo kunokuqikelelwa ngeliso lenyama, nge-engile yedome eyi-32′ 35″ kwi-perihelion kunye ne-31′ 31″ kwi-aphelion, enika i-radius ephakathi kwe-32′ 03″ . Umxube wemilinganiselo kunye neendlela zeLanga kunye ne luna zinjalo kangangokuba zijongwa malunga nomthamo oqikelelwayo ofanayo esibhakabhakeni. Oku kufikelela kumlinganiselo omkhulu wokusithwa kwelanga yinyanga okwahlukileyo (iphelele, i-annular okanye inxenye).
Ngakolunye uhlangothi, umphumo obanzi weLanga eMhlabeni uye waqatshelwa ukususela kumaxesha e-paleolithic kwaye uye waxatyiswa ngamanye amasiko njengeqhawe. Ukuhamba koMhlaba ecaleni kweLanga sisihlalo sekhalenda yelanga, eyialmanac esetyenziswayo namhlanje.
ukwakheka kwelanga
El Sol Idityaniswe ngamanani ahlukeneyo kunye neeklasi zomphunga kunye nazo zonke iileya zayo, ngakumbi nge-25% ye-helium, i-74% ye-hydrogen kunye nezinye zithengiswa kwiiseti ezingalinganiyo zesulfure, i-oksijeni, i-magnesium, i-neon, i-nitrogen, i-silicon, phakathi kwabanye.
Lo mphunga utshintshwa kwiindawo zeLanga eziqala kwi-aura, indawo yoguqulo, emva koko ichromosphere, ifotosphere, indawo eqhagamshelayo yokuthumela ngaphandle, umda i-tachocline, ulwandiso lothutho lwemitha kunye ne-axis ekugqibeleni, apho isixa esikhulu segesi sikhoyo, ngakumbi i-hydrogen yokuphunyezwa kwempendulo yokudibanisa kwenyukliya ukudala i-helium.
Izigqibo malunga nokuba ilanga yiplanethi, inkwenkwezi okanye isathelayithi
Ngaphambi kokuba uchaze ukuba ilanga liplanethi, inkwenkwezi okanye isathelayithi, kubalulekile ukuchaza okokugqibela. Isathelayithi yinto ephilayo yasezulwini, ihlelwe njengelizwe elinamafu elihamba kwi-orbit ekufutshane neplanethi ethile, ekucingelwa ukuba isuka kungquzulwano lomnye umzimba kunye nenkwenkwezi ekuthethwa ngayo, izikhupha kuqweqwe lwe-astral, njengoko injalo. imeko yeNyanga, okanye banokuba njalo amatye, iimeteorite okanye iikhomethi ezingena kumjikelezo wendalo iphela zize zisilele ukumka.
Ngesi sizathu, iisathelayithi zincinci kuneplanethi yokuqala, nangona kunjalo, ezinye zinobukhulu obukhulu obunokufikelelwa ngendlela yokubini. ii-orbits, ekubeni zinokugqalwa njengezijikelezi-langa ezimbini.
Ngolu lungelelwaniso lwemibono, esele inombonakaliso ocacileyo wento eyiLanga kunye nokuba yintoni isathelayithi, sinokuqonda kakuhle ukuba iLanga isatellite, yaye impendulo nguhayi oqinisekileyo.
Kulula ukuqaphela ngeenkcukacha ezinikiweyo, ukuba iLanga alivumelani nayo nayiphi na kwezo satellite inazo, kuba ingeyonkwenkwezi enamafu, ayincinci kunezinye iiplanethi kwaye ngokuqinisekileyo ayijikelezi. iplanethi, nangona kunjalo thina ukuba sisondele kuyo.
Kulula ukuqikelela, singazi ngokuchanekileyo ukuba iLanga libekwe njani, ukuba ngokuzahlula kumthamo ofanayo noweNyanga, makhe sihlolisise ukuba yisathelayithi, kwaye abaninzi bade bakhusele le ngcamango kuba iLanga lijikeleza kufutshane neNyanga. Indlela yobisi okanye iGalaxy yeLanga, nangona kunjalo, nangona oku akuseyiyo i-satellite, kuba ukuze ihlolwe ngolo hlobo, kufuneka ijikeleze inkwenkwezi ethile.
Ke, sele siyayazi impendulo yokuba iLanga lisathelayithi, kodwa ngoku kuvela omnye umbuzo, ngakumbi ukuba Sol Kwaye siyayahlula njani loo nto?
ILanga luchungechunge oluphambili lwenkwenkwezi yodidi lwe-G, ekwabizwa ngokuba yintlupheko etyheli okanye etyheli yodidi lwe-G, oku kubonisa ukuba xa kuthelekiswa nabanye. iinkwenkwezi, i-Sun isenomlinganiselo omncinci kakhulu, nangona kunjalo, iya kunyuka ngaphezu kweminyaka, ngokudibanisa kunye nokutshintsha kwe-hue ibe bomvu. ILanga linokubangela ukukhanya kwalo, kunye namandla ngokwawo, uphawu olungenako ukwenza iisathelayithi.
Kumkani wethu weenkwenkwezi, akukho nto iphikisana neenkwenkwezi ngobusuku emva kobusuku siqaphela esibhakabhakeni, ngokuqhelekileyo xa kukho inyanga entsha, kwaye ikhanya kwaye ibengezela intsasa yonke. Into ethatha indawo yayo yindlela ezikuyo kwiSolar System kunye neenkwenkwezi, ngakumbi Umhlaba.
Okokugqibela, xa sisazi ukuba ilanga sisijikelezi-langa, inkwenkwezi okanye isathelayithi, sinokubona ukuba eyethu inkanyezi ibonakala inkulu esibhakabhakeni sethu, ngoxa ezinye zikhangeleka zincinane xa zithelekiswa. Mhlawumbi, ukusuka kwisijikelezi-langa esijikelezayo kwezo nkwenkwezi, iLanga likhangeleka ngendlela efanayo njengoko sahlula ngayo ezinye, zomlinganiselo ofana kakhulu nendawo eqaqambileyo.
