King is a prominent lunar impact crater that is located on the far side of the Moon, and can not be viewed directly from Earth. It forms a crater pair with Ibn Firnas, which is only slightly larger and is attached to the northeast rim of King.
The outer rim of King is roughly circular but with a slightly irregular appearance, particularly at the northern end. The inner wall is multiply terraced, and is not heavily worn. The interior is irregular and ridged, particularly in the western half. The central peak is part of a ridge formation that runs to the southern rim.
Satellite craters
By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to King crater.
Complex craters have a raised central peak surrounded by a trough and a fractured rim.
Craters that have been obliterated by erosion over thousands of years, leaving only a circular scar on the earth’s surface, are called astroblemes.
Craters are also commonly formed at the surface opening, or vent, of erupting volcanoes, particularly of the type called cinder cones, where the lava is extruded rather explosively.
