Iyini isimiso 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.  Kunenani elingaziwa lamaplanethi amancane angama-dwarf kanye nemizimba emincane engenakubalwa ye-Solar System ezungeza iLanga. Amaplanethi ayisithupha amakhulu, amaplanethi ayisithupha amakhulu kunawo wonke ama-dwarf, nemizimba eminingi emincane izungezwa iziphuphutheki zemvelo, ezivame ukubizwa ngokuthi "izinyanga" ngemuva kweNyanga yoMhlaba. Amaplanethi amabili emvelo, inyanga kaJupiter uGanymede nenyanga kaSaturn iTitan, makhulu kuneMercury, iplanethi encane kunazo zonke emhlabeni, nakuba ingeyona inkulu kangako, kanti inyanga kaJupiter iCallisto icishe ibe nkulu. Iplanethi ngayinye enkulu neminye imizimba emincane izungezwe izindandatho zeplanethi zeqhwa, uthuli nezinyanga ezincane. Ibhande lezinkanyezi ezincane, eliphakathi kwemijikelezo kaMars noJupiter, liqukethe izinto ezenziwe ngetshe, insimbi neqhwa. Ngaphandle komjikelezo kaNeptune kunebhande likaKuiper nediski ehlakazekile, okuyizixuku zezinto ezakhiwe ikakhulukazi yiqhwa namadwala.
Igama elithi solar lisho ukuthi "eliphathelene neLanga", elivela egameni lesiLatini elithi sol, elisho iLanga. Ilanga yilona elilawula amandla adonsela phansi esimisweni sonozungezilanga, futhi isimiso salo samaplanethi sigcinwa esimweni esizinzile, esishintsha kancane ngokulandela imijikelezo ehlukanisiwe, eboshwe amandla adonsela phansi ezungeze iLanga
