Lockyer (lunar crater)

Lockyer is a lunar impact crater that is located along the western wall of the large walled plain Janssen. It was named after British astrophysicist Norman Lockyer.[1] This crater is roughly circular with a slight outward bulge along the eastern side. The edge of the rim is only lightly eroded, with an indentation in the side to the north-northwest. The interior floor is relatively featureless, except for a small crater along the edge of the southern inner wall.
