Cracks form in the impact melt sheet on the floor of Necho Crater. Imaged by NASA's Lunar Reconnaissance Orbiter.

Necho is a lunar impact crater on the far side of the Moon, and therefore cannot be seen directly from the Earth. It lies to the northeast of the larger crater Langemak, and about a crater diameter to the south-southwest of Bečvář.

The most distinctive aspect of this crater is the prominent ray system that surrounds the outer rim. This higher-albedo skirt of ejecta extends in a nearly continuous fashion out for several crater diameters, but is more extensive to the north and northeast than elsewhere. Beyond this continuous skirt, occasional rays and wisps of light material extent outwards for many more crater diameters.

The outer rim of Necho is somewhat uneven in form, particularly along the western side where it possesses two inner sides that overlap in almost spiral-like fashion. The rim has a slight outward bulge to the east, and is more uneven along that edge. The inner wall and floor has a high albedo, giving the crater a bright appearance. The inner side is generally wider on the western side, and the interior floor is offset to the eastern half.

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 Necho.
