Location of the lunar crater Mitchell

Mitchell is a lunar impact crater, which is attached to the eastern rim of the larger and more prominent crater Aristoteles. It was named after American astronomer Maria Mitchell.[1] The floor of Mitchell is rough and irregular, with a low central rise, being partially filled with the ejecta of the younger Aristoteles. There is a slight notch in the southern rim, and the western wall has been completely absorbed by the rim of Aristoteles.

Features

[edit]

It is characterised by an extremely high rockfall density by lunar standards.[2]: 2 

Satellite craters

[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint which is closest to Mitchell.
