WARNING: the LPI's list of orbital Apollo photographs of Mare Nubium shows a series of Apollo 17 photographs. Impossible because Apollo 17's belt of orbits was way too north to make detailed photographs of Mare Nubium! (which was behind or very near the curved southern horizon).- DannyCaes DannyCaes Jul 30, 2010

Description

The pre-Nectarian Mare Nubium covers geographically nearly two-thirds of the area under study, centred at 21.3 S 16.6 W. Its official name since 1935, Mare Nubium, or “Sea of Clouds”, derives from early telescopic observations. The mare’s numerous ghost features, and various higher-albedo crater ejecta criss-crossing the basin, conjured up the idea of lunar clouds.

Mare Nubium has a diameter of 750 km, and it is one of the most ancient circular basins on the Moon (Stuart-Alexander and Howard, 1970). Nevertheless, there is clear evidence that the basin did not form by a single large impact. Its present morphology appears to be a consequence of a number of major collisions. Morphological evidence of at least four major basin rings is still clearly identifiable (i.e. De Hon, 1977).

Additional Information

On September the 11th of 2013, a bright impact flash was observed at Mare Nubium. See LPOD Forming a New Crater.

Nomenclature

The IAU feature name means "Sea of Clouds".
  • Named Continens Meridionalis (Southern Continent) in pre-telescopic sketch map by William Gilbert in ~1600. Name also included Cognitum, Insular and Humorum! [Whitaker: Mapping and Naming the Moon, p 15]
  • The impact basin is named after the mare.
