to the south-southeast. Both valleys radiate away from the impact basin to the north.
The outer wall of Baade remains sharp-edged, with little appearance of erosion due to subsequent impacts. The rim is generally circular, with some terracing of the inner wall. The crater interior is rough and irregular, with a generally bowl-shaped appearance that lacks a sharply defined floor. There is no central peak at the midpoint of the interior, and no craterlets of note mark the surface.
This crater lies within the
Nectarian
The Nectarian Period of the lunar geologic timescale was from 3.920 billion years ago to 3.850 billion years ago. It is the period during which the Nectaris Basin and other major basins were formed by large impact events. Ejecta from Nectaris for ...
