PROBLEM: Occlusion by this astronomical body of Saggitarius Tr-180 suggests that the rate of sublimation from its surface has doubled. That sublimation may have helped to create evaporite deposits such as the Akupara and Rem maculae, which cover a surface of beta-hexagonal ice surrounding the Plain of Abatus. Its changing albedo is believed to couple with gravitational diapirism to produce the cavi of its unique terrane of Bubeme. Perhaps the most interesting surface features occur in its equatorial region, which contains fault-block mountain ranges bounded by the Ho and Lo sulci, indicating a tectonic past, and the geyser plumes Hili and Mahilani, which contribute to its thin atmosphere. FTP, name this moon of Neptune best known for its cryovolcanic eruptions and its retrograde orbit.

SOLUTION: Science
