Ngokusekelwe kulesi siqephu, yiziphi izinto ezimbili ezakha ingxenye enkulu yesimiso sethu sonozungezilanga?
Context:I-Solar System[c] uhlelo oluboshwe ngamandla adonsela phansi elanga kanye nezinto ezizungezayo. Yakhiwa eminyakeni eyizigidi eziyizinkulungwane ezingu - 4,6 edlule ngenxa yokuwohloka kwamandla adonsela phansi kwefu elikhulu lamangqamuzana eliphakathi kwezinkanyezi. Ingxenye enkulu (99.86%) yesisindo sohlelo iseLangeni, kanti iningi lesisindo esisele likhona kwiplanethi iJupiter. Isimiso samaplanethi esizungeza iLanga siqukethe amaplanethi ayisishiyagalombili. Amaplanethi amane angaphakathi esimisweni - iMercury, iVenus, uMhlaba noMars - angamaplanethi asemhlabeni, akhiwe ngokuyinhloko ngamadwala nezinsimbi. Amaplanethi amane amakhulu asesimisweni sangaphandle makhulu kakhulu futhi anamandla kakhulu kunalawo asemhlabeni. Ezimbili ezinkulu kunazo zonke, iJupiter neSaturn, ziyizinkanyezi ezinkulu zegesi, ezakhiwe ngokuyinhloko nge-hydrogen ne-helium; ezimbili ezilandelayo, i-Uranus neNeptune, ziyizinkanyezi ezinkulu zeqhwa, ezakhiwe ngokuyinhloko ngezinto ezincibilikayo ezinamaphuzu ancibilikayo aphakeme kakhulu uma kuqhathaniswa ne-hydrogen ne-helium, njengamanzi, i-ammonia, ne-methane. Wonke amaplanethi angu - 8 anezindlela ezicishe zibe yisiyingi eziseduze nendawo ezungeza umhlaba, ebizwa ngokuthi i - ecliptic. https://en.wikipedia.org/wiki/Solar_System
Ngokusho kwalesi sigaba, iLanga neJupiter yizinto ezimbili ezakha iningi lomthamo wohlelo lweSolar, neLanga elibhekele i-99.86% yenani eliphelele.
