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.
