Kubva pamharadzano yakapiwa, bvisa chinhambwe chiri pakati peMercury neZuva muAU apo iri pedyo zvikuru nezuva mumugwagwa wayo.
Context:Mercury (0.307<unk>0.588 AU (45.9<unk>88.0 miriyoni km; 28.5<unk>54.7 miriyoni mi) kubva kuZuva) ndiyo nyika yepedyo kuZuva. Nyika duku zvikurusa muSystem yeZuva (0.055 MEarth), Mercury haina masatellite omuzvarirwo. Zvimiro zvikuru zve geological zvine impact craters kana mabheseni ane ejecta magumbeze, zvisaririra zvebasa rekutanga remakomo anoputika kusanganisira magma kuyerera, uye lobed ridges kana rupes izvo zvingangove zvakagadzirwa nenguva yekudzikira pakutanga munhoroondo yepasi. Mamiriro okunze eMercury asina kusimba zvikuru anoumbwa nezvikamu zvinobva kumhepo yezuva zvinobatwa nemagineti eMercury, uyewo maatomu anobviswa pamusoro payo nemhepo yezuva. Musimboti wayo wesimbi wakakura uye jira rayo rakapfava hazvisati zvanyatsotsanangurwa. Zvimwe zvinofungidzirwa ndezvokuti matanda aro okunze akaparadzwa nokubonderana kukuru, kana kuti akadziviswa kuwanda zvizere nesimba reZuva rakanga richiri duku. Kwave kune kutsvaka "Vulcanoids", mapuraneti ari mumakwara akatsiga ari pakati peMercury neZuva, asi hapana akawanwa.
Mercury ine nzvimbo yakaita sezai. Daro riri pakati peZuva neMercury apo Mercury inenge iri pedyo zvikuru nezuva iri munharaunda yayo iri 0.307 AU.
