The kuvapo mvura chando kunotsigirwa infrared spectroscopic observations, izvo zvakaratidza crystalline mvura pamusoro pemwedzi. mvura chando absorption zvisungo vane simba pamusoro Umbriel kuti kutungamirira hemisphere pane trailing hemisphere. chikonzero ichi sezvo symmetry haisi kuzivikanwa, asi zvingava zvachose chokuita bombardment kubudikidza charged particles kubva magnetosphere Uranus, izvo zvakasimba pamusoro mwedzi hemisphere, izvo zvinoratidza kuti zvikurukuru inoumbwa mvura chando, ane gobvu asiri chando chinoumba kumativi 40% yayo vakawanda. yokupedzisira aigona kuitwa dombo uye carbonateous zvinhu kusanganisira inorema makemikari anozivikanwa tholins. Kuvapo mvura chando kunotsigirwa ne infrared spectroscopic observations, izvo zvakaratidza crystalline mvura pamusoro mwedzi. mvura chando absorption zvisungo vane simba pamusoro Umbriel kuti kutungamirira hemisphere pane trailing hemisphere.
