Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Io inotenderera Jupiter iri kure nemakiromita 421,700 kubva pakati paJupiter uye makiromita 350,000 kubva kumusoro kwemakore ayo. Iyo ndiyo iri mukati-kati memasataiti eGalealeylian aJupiter, kutenderera kwayo kuri pakati peaya eThebe neEuropa. Kubatanidza mwedzi yomukati yeJupiter, Io mwedzi wechishanu kubva kuJupiter. Zvinotora Io maawa anenge 42,5 kuti apedze kutenderera Jupiter kamwe chete (anokurumidza zvakakwana kuti kufamba kwaro kuonekwe usiku humwe hwokucherechedza). Io iri mu 2:1 mean-motion orbital resonance neEurope uye 4:1 mean-motion orbital resonance neGanymedes, ichipedza maorbit maviri aJupiter nokuda kweimwe orbit yakapedzwa neEurope, uye maorbit mana nokuda kweimwe yakapedzwa neGanymedes. Kuwirirana uku kunobetsera kuchengeta eccentricity yomugwagwa yaIo (0.0041), iyo nenzira yayo inopa manyuko okutanga okupisa nokuda kwebasa rayo rezvokuita zvepasi. Pasina iyi eccentricity yakamanikidzwa, nharaunda yeIo yaizotenderera kupfurikidza nokuparara kwemvura, kuchitungamirira kunyika isingashandi zvikuru mune zveji.  Mubvunzo: Mwedzi wechishanu waJupiter unotora nguva yakareba sei kuti udzokere panzvimbo yayo?
