Cichus (Moon)

Named after Francesco Degli Stabili (Cecco D'Ascoli) Cichus - Italian astronomer (1257-1327).

Cichus is a lunar impact crater that lies in the southwestern part , at the eastern edge of Palus Epidemiarum. Just to the northeast and nearly contacting the rim is the lava-flooded crater remnant Weiss. The rim of this crater is only slightly worn, although the crater Cichus C lies across the southwestern rim. Sections of the inner wall are terraced, and the western side is somewhat wider than in the east. (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.
