Colongitude	241° at sunrise
Eponym	Arthur S. King Edward S. King

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 pair with Ibn Firnas, which is only slightly larger and is attached to the northeast rim of King. To the northwest is the crater Lobachevskiy, and Guyot is located an equal distance to the north-northwest.

The outer rim of King is roughly circular but with a slightly irregular appearance, particularly at the northern end. The crater displays little appearance of wear. The inner walls are terraced, particularly along the eastern side. Within the walls is a somewhat uneven interior floor. The interior is irregular and ridged, particularly in the eastern half. The elongated, Y-shaped central rise is part of a ridge that runs to the southern rim.

A tiny crater near the east-southeastern inner wall has been officially given the Indian feminine name Sita by the IAU. It is located at selenographic coordinates 4.6° N, 120.8° E, and has a diameter of 2 kilometres.

Due to its prominent rays, King is mapped as part of the Copernican System.

Prior to naming in 1970 by the IAU, this crater was known as Crater 211.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to King.

King	Latitude	Longitude	Diameter
J	3.2° N	121.8° E	14 km
Y	6.5° N	119.8° E	48 km

King Y is to the north of King, and it is now a "pool" of impact melt, filled at the time of the King impact. The name "Al-Tusi" had been suggested for King Y, but this was not approved by the IAU. King J is a small crater to the southeast of King, and it is covered by King's ejecta blanket.

Mountain Peaks

Several mountain peaks (Montes) within King crater have been named. The names were approved by the IAU in 1976.

Mons	Latitude	Longitude	Approximate Altitude
Andre	5.18° N	120.56° E	7000 m
Ardeshir	5.03° N	121.04° E	5900 m
Dieter	5.00° N	120.30° E	8000 m
Dilip	5.58° N	120.87° E	5500 m
Ganau	4.79° N	120.59° E	7900 m
