Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Umbriel ita ce ta uku mafi girma kuma ta huɗu mafi yawan taurari na Uranus. Yawan wata shine 1.39 g / cm3, wanda ke nuna cewa yafi kunshe da ruwan kankara, tare da ɓangaren da ba kankara ba wanda ya kai kusan kashi 40% na nauyinsa. Ana iya yin waɗannan daga dutsen da kayan carbonate ciki har da mahaɗan ƙwayoyin halitta masu nauyi da aka sani da tholins. Ana tallafawa kasancewar ruwan kankara ta hanyar lura da infrared spectroscopic, wanda ya bayyana ruwan kankara mai haske a saman wata. Rukunin shan ruwan kankara sun fi karfi a kan gabashin duniya na Umbriel fiye da na baya. Ba a san dalilin wannan asymmetry ba, amma yana iya danganta shi da harin da ake yi da barbashi daga magnetosphere na Uranus, wanda ya fi karfi a kan hemisphere na baya (saboda haɗin gwiwar plasma). Kwayoyin da ke da kuzari suna da saurin zubar da ruwan kankara, suna lalata methane da aka kama a cikin kankara a matsayin clathrate hydrate kuma suna baƙar fata sauran kwayoyin, suna barin duhu, mai wadataccen carbon. Ban da ruwa, kawai sauran mahaɗan da aka gano a farfajiyar Umbriel ta hanyar infrared spectroscopy shine carbon dioxide, wanda aka mai da hankali musamman a ƙarshen ƙarshen duniya. Ba a san ainihin inda iskar carbon dioxide take fitowa ba. Ana iya samar da shi a cikin gida daga carbonates ko kayan ƙwayoyin halitta a ƙarƙashin tasirin kuzari mai kuzari da ke fitowa daga magnetosphere na Uranus ko hasken ultraviolet na hasken rana. Wannan hasashen zai bayyana rashin daidaituwa a cikin rarrabawar sa, kamar yadda ɓangaren ɓangaren baya ke ƙarƙashin tasirin magnetospheric mai ƙarfi fiye da ɓangaren da ke gaba.

Tserewa na CO2 daga ciki na iya zama sakamakon ayyukan ilimin ƙasa na baya a wannan wata.Umbriel na iya bambanta cikin tsakiya mai dutse wanda ke kewaye da mayafin kankara. Idan haka ne, radius na tsakiya (317 km) shine kimanin 54% na radius na wata, kuma nauyinsa yana kusa da 40% na moon's mass<unk>parameters an tsara...  Tambaya: Uranus ya buge watanninsa da wane irin barbashi?
