Ziziphi iiNdandatho zeSaturn?

ISaturn yiplanethi yesithandathu ukusuka kwiLanga kunye neyesibini ngobukhulu kwiplanethi yethu yelanga. Iiplanethi ezininzi zinemisesane, kodwa izangqa zeSaturn ezinomkhenkce, ezintsonkothileyo ziyibango leplanethi yodumo. ISaturn sisigebenga segesi esenziwe ngehydrogen kunye nehelium.

ISaturn yaqala ukufunyanwa kumaxesha amandulo inamehlo angancediswa mntu. Iplanethi ithiywe ngothixo waseRoma wezolimo nobutyebi. USaturn naye wayenguyise wesithixo saseRoma uJupiter, ngoko ke izigebenga zerhasi zabelana ngomnombo wosapho ngokwamagama azo.

Imishini yeSaturn yeNASA

I-NASA ithumele iziphekepheke ezine zerobhothi, iPioneer 11, iVoyager 1, iVoyager 2, kunye neCassini ukuba zijonge uSaturn. Baqokelela idatha eninzi kwiindandatho zeSaturn. Izangqa ngokwenene zizibhanti zamasuntswana agcinwe kwindawo ekhawuleza kakhulu, imimoya enamandla ejikeleza iplanethi. Izangqa zimalunga neekhilomitha ezingama-400,000, okanye iimayile ezingama-240,000, ububanzi. Ukubeka imilinganiselo enjalo, ububanzi beendandatho zeSaturn bulingana nomgama phakathi koMhlaba nenyanga. ISaturn ijikelezwe ngamakhonkco angama-100 ukuya kuma-500.

Ukuqulunqwa kwezangqa

Izangqa zeSaturn ziziimitha ezili-100 kuphela, okanye iinyawo ezingama-330, ubukhulu. Amasuntswana abumba amakhonkco ahluka ngobukhulu ukusuka kwi-minuscule ukuya kubukhulu bebhasi. Izazinzulu zikholelwa ukuba amasuntswana amakhulu alingana nebhasi ziibhola zekhephu eziqinileyo okanye amatye avalelwe emkhenkceni. Izangqa zenziwe ngamasuntswana amancinane. Amasuntswana amaninzi ngumkhenkce namanzi anezixa ezithe kratya zamatye.

Cassini

Isiphekepheke saseCassini esithwele i-Huygens probe saphehlelelwa ngo-1997. Yayisiphekepheke sokuqala ukuba sifike ngenene kwi-orbit ye-Saturn, kwaye safika eSaturn ngoJulayi ka-2004. I-Cassini yajikeleza iSaturn iminyaka eyi-13, yaze yaqokelela iinkcukacha ezibanzi kwizangqa zeSaturn. I-Huygens probe yathunyelwa kwi-parashute kwi-atmosphere ye-Titan, inyanga enkulu ye-Saturn. I-Cassini yagqiba umsebenzi wayo ngoSeptemba ka-2017 ngokuntywila kwi-atmosfera ye-Saturn kwiseti enye yokugqibela yedatha.

ISaturn

ISaturn sisigebenga esikhulu segesi esikhulu ngokwaneleyo ukuba singaqulatha i-760 Earths. Ikwasesona sijikelezi-langa sixinene kancinci kwisixokelelwano sethu selanga. ISaturn incinci kakhulu kunamanzi, okuthetha ukuba iplanethi iya kudada kumzimba wamanzi amakhulu ngokwaneleyo. Ubuninzi obuphantsi bungumphumo wokubunjwa kweSaturn. Isijikelezi-langa senziwe ubukhulu becala zizinto ezimbini ezikhaphukhaphu, ihydrogen kunye nehelium. Iibhanti ezityheli negolide kwiatmosfera yeSaturn zivela kwimimoya ekhawuleza ngokumangalisayo kwiatmosfera ephezulu. Isantya somoya sinokufikelela kwi-1,100 yeemayile ngeyure malunga ne-ikhweyitha yeSaturn.

Ukujikeleza kukaSaturn

ISaturn ijikeleza ngokukhawuleza kunayo nayiphi na iplanethi ngaphandle kweJupiter. Ukujikeleza okukhawulezayo kubangela ukuba iSaturn ijikeleze i-ikhweyitha kwaye ijikeleze iipali. ISaturn ibanzi ngeemayile ezingama-8,000 kwi-ikhweyitha kuneepalini. ISaturn ithatha iminyaka engama-29 yoMhlaba ukugqiba omnye weminyaka yayo. Oku kubonakala kungaqhelekanga kuba iSaturn inomjikelezo okhawulezayo, kodwa ubukhulu beplanethi kufuneka buthathelwe ingqalelo. Ihexagon enkulu kwipali esemantla yeSaturn yafunyanwa okokuqala nguVoyager, kodwa uCassini waphinda wayiphinda. Imalunga neemayile ezingama-7,500 ukunqumla kwaye ibonakala ifikelela kwiimayile ezingama-60 ezantsi kwiplanethi. Izazinzulu aziqinisekanga ukuba yintoni na ihexagon.

Ulwakhiwo lweeNdandatho zeSaturn

Iindandatho zikaSaturn zifana ne-disc eneendawo ezahlukeneyo zokuxinana kunye nokukhanya. Izikhewu ezininzi apho ukuxinana kwamasuntswana kwehla kakhulu kuthe saa kuzo zonke iindandatho. Izikhewu zikwakhona kwiindawo ezaziwayo zokungcungcuthekisa ii-orbital resonances ezibangelwa ziinyanga zikaSaturn. I-resonances ezinzileyo, ekwabangelwa yinyanga, ibalulekile kwisigxina samakhonkco amaninzi, kuquka i-Titan Ringlet kunye ne-G Ring.

Ring Imvula

Isenzeko esibizwa ngokuba 'yimvula ejikelezayo' yenzeka ngoSaturn. Abaphandi bayazi ukuba imvula yeringi yimvula eyenziwe ngamanzi akhutshwe kwizangqa zeSaturn. Izazinzulu ziye zajonga imvula kangangeeyure ezimbalwa ukusuka eHawaii ngo-2011. Uhlobo olukhethekileyo lwehydrogen olukhanya kukukhanya kwe-infrared lukho kuyo yonke imvula yesangqa yeSaturn. Izazinzulu ziye zagweba umthamo kunye nendawo yemvula yesangqa ngokujonga ihydrogen.

Ukulahlekelwa iiNdandatho zeSaturn

Umthamo wemvula wendandatho ebonwayo ngexesha leeyure zabo zokujonga kwanele ukususa phakathi kwe-925 ukuya kwi-6,000 yeepounds zezinto ezivela kwiindandatho zeSaturn nganye yesibini. Izazinzulu zibale i-300 yezigidi zeminyaka yokuphila yeringi zisebenzisa ireyithi kunye nomthamo wemvula yeringi edityaniswe nobunzima bangoku bezangqa zeSaturn. UCassini ufumene olunye uhlobo lwemvula yeringi ebizwa ngokuba 'yi-infall' ngaphakathi kweSaturn. Xa umthamo we-infall wongezwa kwizibalo zangaphambili, izazinzulu zaqaphela ukuba iindandatho zeSaturn zinokuthi zihambe ngaphantsi kwe-100 yezigidi zeminyaka. Oko kubonakala ngathi lixesha elide kakhulu, kodwa alikho lide kwaphela ngokwenkqubo yelanga. Izazinzulu zikholelwa ukuba uJupiter, u-Uranus, kunye neNeptune babenemisesane efana kakhulu nekaSaturn ngaxeshanye, kodwa kukho iintsimbi ezicekethekileyo ezijikeleze ezo planethi ngoku.

Phoebe Ring

Izangqa ezisixhenxe ezinkulu ezijikeleze iSaturn zine-150,000 yeemayile ububanzi. Umsesane weFibhi ngowona mkhulu, njengokuba uFibhi uyenye yezona nyanga zinkulu zeSaturn. Ixesha elifutshane lokujikeleza likaPhoebe livumele uCassini ukuba afumane idatha ebanzi malunga nenyanga kunye neringi. Umsesane weFibhi wabelana ngentshukumo yayo ye-orbital phakathi kweFibe kunye neSaturn. Izazinzulu zikholelwa ukuba inyanga uFibhi yavela kwibhanti yeKepler kwaye yayinobushushu kunye namanzi angamanzi.

IiNyanga zikaSaturn

ISaturn ijikelezwe ziinyanga ezingama-150 kunye neenyanga. Zonke iinyanga zinomkhenkce kwaye zenziwe ngamanzi, umkhenkce kunye namatye. I-Titan kunye neRhea zezona nyanga zinkulu. I-Titan inomoya onzima, otyebileyo wenitrogen kunye namachibi e-methane engamanzi kunye nezakhiwo ezenziwe yinitrogen enomkhenkce. Ezinye izazinzulu zikholelwa ukuba i-Titan inokugcina ubomi, nangona iya kwahluka kakhulu kubomi basemhlabeni. Izazinzulu ezininzi zikholelwa ukuba iinyanga ezininzi zazo zonke iimilo kunye nobukhulu zidlala indima ekubunjweni kwezangqa zeSaturn.
