Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Vakawanda vanopokana kuti misiyano iri pakati pemapuraneti makuru echando nemapuraneti makuru egasi inowedzera kukuumbwa kwawo. Zvinofungidzirwa kuti Gadziriro yeZuva yakaumbwa nebhola guru rinotenderera remagasi neguruva rinozivikanwa sepresolar nebula. Zvizhinji zvegasi reNebula, zvikurukuru hydrogen nehelium, zvakaumba Zuva, uye tsanga dzeguruva dzakaungana pamwe chete kuti dziumbe mapuraneti okutanga. Sezvo mapuraneti akakura, mamwe awo pakupedzisira akaunganidza zvinhu zvakakwana zvokuti simba rawo rinokweva rakabata gasi rakasara rebhuruu. Magasi akawanda zvaaibata, zvaiwedzera kukura; zvaiwedzera kukura, magasi akawanda zvaaibata kusvikira panguva inokosha yasvika, uye ukuru hwawo hwakatanga kuwedzera zvikuru. Zvikara zveaizi, zvine uwandu hwepasi hushomanene bedzi hwegesi yebhuruu, hazvina kutongosvika papfundo rakakomba iroro. Kufananidzira kuchangobva kuitwa kwekutama kwemapuraneti kwakaratidza kuti mapuraneti makuru maviri echando akaumbwa ari pedyo neZuva kupfuura zvaari iye zvino, uye akabuda kunze mushure mekuumbwa (muenzaniso weNice).  Mubvunzo: Kufananidzira kuchangobva kuitwa kwekutama kwemapuraneti kwakaratidzei?
hofori dzeaizi dzakaumbwa dziri pedyo neZuva kudarika nzvimbo dzadzo dzazvino
