EponymJoseph Ashbrook

Ashbrook is a largelunarimpact crater that is located in the vicinity of the south pole on thefar side of theMoon, and so cannot be viewed directly from theEarth. The eastern face of the crater has been overlain by the similar-sizedDrygalski, and more than half the interior floor of Ashbrook is covered by the outerramparts and ejecta of Drygalski. To the northwest is the walled plainZeeman.

The surviving outer rim of Ashbrook is worn and eroded by subsequent impacts, although much of the original formation is still visible. If the crater once possessed a central peak, it is now buried by the ejecta from Drygalski. Only a section of the interior floor near the southwest rim is flat, being marked only by tiny craterlets.

This crater was previously designated Drygalski Q before being assigned a name by theIAU.
