Mare Nectaris

Montes Pyrenaeus borders the mare to the east and Sinus Asperitatis fuses to its northwestern edge.

A prominent trio of 100-km craters Theophilus, Cyrillus and Catharina is located near northwestern coast.

Other notable feature is a "ghost crater" Daguerre, almost entirely covered with lava, in the northern part of Mare Nectaris.

[3] Mare Nectaris is located in the central part of 860-km-diameter impact basin, which was formed 3.8–3.9 billion years ago.

[6] A mass concentration (mascon), or gravitational high, was identified in the center of Mare Nectaris from Doppler tracking of the five Lunar Orbiter spacecraft in 1968.
