I-Jupiter
I-Jupiter (uphawu: .svg){kind=small}
) yiplanethi yesihlanu yesixokelelwano selanga ngokulandelelana komgama ukusuka eLangeni kunye neyona inkulu kuyo yonke inkqubo yeplanethi : ubunzima bayo buhambelana namaxesha amabini anesiqingatha inani lazo zonke ezinye iiplanethi ezidityanisiweyo. [1] Ihlelwa, njengeSaturn, i-Uranus kunye neNeptune, njenge-gas giant (ezimbini zokugqibela zihluke ekubeni zihlelwe kumaxesha amva nje njengeengxilimbela ezinomkhenkce).
I-Jupiter inokwakheka okufana neLanga : enyanisweni yenziwe kakhulu yi -hydrogen kunye ne-helium enemilinganiselo emincinci yezinye iigesi ezidibeneyo, ezifana ne-ammonia i-methane kunye namanzi. Kukholelwa ukuba iplanethi inesakhiwo esinemaleko amaninzi, kunye nesiseko esiqinileyo, ekucingelwa ukuba yindalo yamatye kwaye yenziwe nge -carbon kunye ne-silicates yentsimbi, apho i- mantle ye-metallic ye-hydrogen inobunzima kunye nesigqubuthelo esikhulu se-atmospheric bacinezela kakhulu kuyo.
Umoya wangaphandle ubonakaliswe ngamaqela amaninzi kunye neendawo ze-shades ezihluka ukusuka kwikhilimu ukuya kumdaka, ofakwe kwi-cyclonic kunye ne-anticyclonic formations, phakathi kwayo i- Great Red Spot ivelele. [2] Ukujikeleza okukhawulezileyo kweplanethi kuyinika inkangeleko yespheroid ethe tyaba ezipalini kwaye ivelise imagnethi emandla eyenza i- magnetosphere ebanzi; ngaphezu koko, ngenxa ye-Kelvin-Helmholtz mechanism, i-Jupiter (njengazo zonke ezinye izigebenga zerhasi) ikhupha isixa esikhulu samandla kunokuba iwafumana eLangeni
Ngenxa yobukhulu bayo kunye nokwakheka okufana noko kweLanga, iJupiter kudala ithathwa njenge " nkwenkwezi engaphumeleliyo ": eneneni kuphela ukuba ibinethuba lokunyusa ubunzima bayo ukuya kuma-75-80 amaxesha angoku [ 2 [3] undoqo wayo ngewube ubambe ubushushu kunye neemeko zoxinzelelo ezivumayo ukuqalisa ukuhlangana kwe-hydrogen kwi-helium, nto leyo ebiya kwenza inkqubo yelanga ibe yinkqubo yeenkwenkwezi zokubini. [4]
Ummandla onzulu womxhuzulane kaJupiter unempembelelo kwisakhiwo sesijikelezi-langa ngokuphazamisa imijikelo yezinye iiplanethi kwaye ngokuyinxenye “uyicoca” inkunkuma enokubetha kwezona planethi zingaphakathi. [5] Iisathelayithi ezininzi [6] kunye nenkqubo yamakhonkco angabonakaliyo ajikeleza iJupiter; isenzo esidibeneyo semimandla ye-gravitational ye-Jupiter kunye ne-Sun iphinda izinze ii-orbits zamaqela amabini e-Trojan asteroids. [7]
Isijikelezi-langa, esasisaziwa ukususela kumaxesha amandulo, siye sadlala indima enkulu kwiinkolelo zonqulo zezithethe ezininzi, kuquka amaBhabhiloni, amaGrike namaRoma, awawafanisa nomlawuli wezithixo. [8] Isimboli yeenkwenkwezi yesijikelezi-langa (♃) luphawu olunesitayile lombane, olona phawu luphambili lwesithixo.
