Mare Nubium (Latin nūbium, the "sea of clouds") is a lunar mare in the Nubium basin on the Moon's near side. The mare is located just to the southeast of Oceanus Procellarum.
Formation
The basin containing Mare Nubium is believed to have been part of the Pre-Nectarian system. The mare material is of the Imbrian and Eratosthenian age.
Bullialdus crater, a prominent feature on the west side of the mare, is of Eratosthenian age.{{cite web |archive-date=2012-04-08 |archive-url=https://web.archive.org/web/20120408211024/http://www.oarval.org/MoonMapen.htm |url-status=dead
Names
Like most of the other maria on the Moon, Mare Nubium was named by Giovanni Riccioli, whose 1651 nomenclature system has become standardized. Previously, William Gilbert had included it among the Continens Meridionalis ("Southern Continent") in his map of c.1600, and Michael van Langren had labelled it the Mare Borbonicum (after the House of Bourbon) in his 1645 map.
Exploration
The first released images from the Lunar Reconnaissance Orbiter in 2009 were of the lunar highlands 200 km south of Mare Nubium.{{Cite web | archive-date=August 8, 2009 | archive-url=https://web.archive.org/web/20090808163647/http://www.nasa.gov/mission_pages/LRO/multimedia/lroimages/lroc_20090702_a.html | url-status=dead
