Kinau is a small, eroded lunar crater that is located in the low southern latitudes. It lies to the southeast of the crater Jacobi, and about equally far to the north-northwest of Pentland. It is 42 kilometers in diameter and two kilometers deep. It may be from the Pre-Nectarian period, 4.55 to 3.85 billion years ago. (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.
