Kulik is a lunar impact crater that lies on the northern hemisphere 's far side. The outer rim of this crater has been heavily impacted, particularly along the northern side which is almost entirely overlain by a pair of smaller craters. The southern inner wall is also marked by a cluster of small impacts, and there are small craters across the western rim and notching the eastern inner wall. The interior floor is nearly featureless, but a small central peak rises near the midpoint. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
