Tags: Crater.
Oken is a lunar crater near the southeastern limb of the Moon. It is normally visible from the Earth but is foreshortened and within the region of the surface that is subject to libration. To the south and east of this feature is the broad uneven Mare Australe which extends to the far side of the Moon.The interior of this crater has become flooded by basaltic lava producing a nearly level featureless surface with a low albedo.
