Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mercury inoratidzika kuva ine solid silicate crust and mantle inovhara solid, iron sulfide outer core layer, a deeper liquid core layer, uye solid inner core.Mercury ndeimwe yemapuraneti mana epasi muSolar System, uye ibwe rakafanana nePasi. Ndiyo nyika duku pane dzose muSolar System, ine equatorial radius ye 2,439.7 kilometres (1,516.0 mi). Mercury idukuwo - kunyange zvazvo yakakura zvikuru - kupfuura masatellite makuru omuzvarirwo muSolar System, Ganymede naTitan. Mercury inoumbwa neanenge 70% simbi uye 30% silicate zvinhu. Kuwanda kweMercury ndiko kwechipiri pakukura muSystem yeZuva pa5.427 g/cm3, zvishoma chete pane kuwanda kwePasi kwe5.515 g/cm3. Kana simba rokumanikidzira rinokonzerwa negiravhiti raizobviswa kubva kumapuraneti ose ari maviri, zvinhu zvinogadzirwa naMercury zvaizova zvakasimba kudarika zvePasi, zvine huremu husina kumanikidza hwe5.3 g/cm3 zvichienzaniswa ne4.4 g/cm3 yePasi. Huremu hwaMercury hunogona kushandiswa kutsanangura zvakadzama nezvechimiro chayo chemukati. Kunyange zvazvo kuwanda kwepasi kuchikonzerwa zvikuru nokumanikidzwa kwaro negiravhiti, zvikurukuru pakati paro, Mercury iduku zvikuru uye nharaunda dzaro dzomukati hadzina kumanikidzwa zvikuru. Naizvozvo, kuti ive noukuru hwakadaro, mwoyo wayo unofanira kuva mukuru uye une simbi yakawanda. Nyanzvi dzezvokuchera matongo dzinofungidzira kuti mwoyo waMercury unotora inenge 55% yeuwandu hwayo; nokuda kwaPasi uyu mwero ndi17%. Kutsvakurudza kwakabudiswa muna 2007 kunoratidza kuti Mercury ine nyanga yakanyunguduka. Munharaunda yepakati pane 500<unk>700 km (310<unk>430 mi) yechivharo chinoumbwa nema silicates. Zvichibva pamashoko anobva kuMariner 10 mission uye kuongorora kwepasi, makorari eMercury anofungidzirwa kuva makiromita 35 (22 mi) gobvu. Chimwe chinhu chinosiyanisa pamusoro peMercury kuvapo kwemakomo akawanda akatetepa, anotambanuka kusvika kumakiromita mazana anoverengeka. Kunofungidzirwa kuti izvi zvakaumbwa sezvo nyanga yaMercury nemapfekero zvakatonhora uye zvakabatana panguva apo ganda rakanga ratosimba. Nyanga yaMercury ine huwandu hweiron hwakakwirira kupfuura hweimwe nyika huru muSolar System, uye dzidziso dzinoverengeka dzave...  Mubvunzo: Mercury yakakura sei kana ichienzaniswa nemasatellite ayo anonzi Ganymede naTitan?
