Ashbrook (crater)

157.68

Ashbrook is a large impact crater near the south pole on the side of the moon and therefore can not be observed directly from Earth. Its eastern edge is superimposed by the same large crater Drygalski, and more than half of its interior is buried under the walls and ejecta of Drygalski. Northwest extends the Zeeman crater.

The remaining outer wall of Ashbrook is worn and eroded by subsequent impacts, but still the original lineup is still recognizable. Only a portion of the crater floor near the southwestern edge is flat and marked only by a few small divots. If the crater has possessed a central peak, this is now covered by ejecta from Drygalski.

Marriage Ashbrook in 1994 by the International Astronomical Union ( IAU) got its own name granted, he was known as " Drygalski Q".
