Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Coma Berenices kana Com is dwarf spheroidal galaxy iri muComa Berenices constellation uye yakawanikwa muna 2006 mu data yakawanikwa neSloan Digital Sky Survey. Gwara renyeredzi iri riri kure neZuva ne44 kpc uye riri kubva paZuva nekumhanya kweanenge 98 km/s. Inorondedzerwa segwara renzou duku (dSph) zvichireva kuti ine chimiro che elliptical (ratio of axes ~ 5:3) ine hafu-chiedza cheinenge 70 pc.Com ndeimwe yemasetelliti madiki uye asina kujeka eMilky Way<unk>kujeka kwayo kwakabatana kunenge ka3700 nguva iyo yeZuva (hukuru hunoonekwa hunenge -4.1), iyo yakaderera zvikuru kupfuura kupenya kwehuwandu hwemapoka emagetsi. Zvisinei, uremu hwaro hunenge mamiriyoni 1,2 ezuva, izvo zvinoreva kuti uwandu hwegwara renzou hunenge huchienzana nechiedza chinenge 450. Chiyero chakakwirira chechiedza chinoratidza kuti Com inodzorwa nezvinhu zvakasviba. Simbi dzenyeredzi idzi dzekare dzakadererawo zvikuru pa[Fe/H] ≈ -2.53±0.45, zvinoreva kuti dzine zvinhu zvinorema zvakapetwa ka350 pane zveZuva. Nyeredzi dzeCom dzingangova dzakanga dziri pakati penyeredzi dzokutanga kuumbwa muZvakasikwa uye pari zvino hapana kuumbwa kwenyeredzi muCom. Kusvika pari zvino kuyerwa kwacho hakuna kuratidza kuti kune hydrogen isina kwayakarerekera - muganhu wayo wepamusoro uri pa46 masimba ezuva. Kubatana uku kungaratidza kuti Com yaimbova imwe nyeredzi yeimwe nyeredzi yomurwi iwoyo wegwara renzou.  Mubvunzo: Chii chisati chagadzirwa muCom?
