Eponym Sea of Clouds

Mare Nubium ("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[edit]

The basin containing Mare Nubium is believed to have been part of the Pre-Nectarian system, with the surrounding basin material being of the Lower Imbrian epoch. The mare material is of the Upper Imbrian epoch.[citation needed]

The crater to the west of the mare is Bullialdus,[3] which is of the Eratosthenian Epoch. This means the crater is younger than the mare it sits in.[citation needed] The crater that sits on the southern rim of the mare is Pitatus.

Names[edit]

Like most of the other maria on the Moon, Mare Nubium was named by Giovanni Riccioli, whose 1651 nomenclature system has become standardized.[4] Previously, William Gilbert had included it among the Continens Meridionalis ("Southern Continent") in his map of c.1600,[5] and Michael Van Langren had labelled it the Mare Borbonicum (after the House of Bourbon) in his 1645 map.[6]

Exploration[edit]

The first released images from the Lunar Reconnaissance Orbiter in 2009 were of the Mare Nubium.[citation needed]

News[edit]

In September of 2013, Spanish astronomers observed and recorded an impact event when a large rock hit the lunar surface in Mare Nubium[7]
