Kiess is a lunar crater next to the southern border of the Mare Smythii, near the eastern limb. It is located to the east of the crater Kästner, and to the north of Dale and Kreiken. The interior floor of this crater has been flooded by lava, leaving only a narrow rim above the surface. This surface has a low albedo, and is as dark as the neighboring mare. (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.
