Necho ( Latin: Necho ) is a large impact crater in the equatorial region of the far side of the moon . The name was given in honor of the ancient Egyptian pharaoh Necho II (610-593 BC), who sent the Phoenician expedition around Africa , and approved by the International Astronomical Union in 1976. Crater formation refers to the Copernican period [1] .

Crater Description
The nearest neighbors of the crater are the Vesalius crater in the west-north-west; Bechwarzh Crater in the northeast; Love Crater in the east; Perepelkin crater in the east-southeast; Danjon Crater in the south and Langemak Crater in the southwest [2] . Selenographic coordinates of the center of the crater , diameter 36.9 km [3] , depth 2.0 km [1] .
The Necho crater has a polygonal shape with a small protrusion in the southeastern part and practically has not been destroyed, located on the southwestern part of the rampart of a large nameless crater with a diameter of about 200 km. A shaft with a clearly defined edge, double in the western part. The inner shaft is smooth, with a high albedo , in the western part it has a terrace-like structure and is much wider. The shaft height above the surrounding area reaches 920 m [1] , the volume of the crater is approximately 610 km³ [1] . The bottom of the bowl with a high albedo, crossed with the exception of small sections in the eastern and northern parts, due to the uneven width of the inner slope, the center of the bowl is shifted to the east. In the western part of the bowl there are several ridges, concentric with respect to the western part of the shaft. A little north of the center of the bowl is a group of central peaks and individual hills. The lava melt in the crater bowl formed during the formation of the crater, with further solidification, became covered by a network with a crack 10–15 m wide.
The crater is surrounded by an area of rocks with a high albedo ejected during its formation, with a diameter of several diameters of the crater itself, individual rays stretch to a greater distance.
