C. Mayer is a lunar impact crater that is located at the northern edge of the Mare Frigoris.[3] It is at the western end of the Montes Carpatus range,[4] and due north of the prominent crater Aristoteles. Also to the south, but only a third as distant, is the smaller crater Sheepshanks. Due east of C. Mayer is the flooded crater Kane.[5]

C. Mayer is a relatively young formation, with a sharp-edged and well-defined outer rim. The rim is not quite circular, and appears somewhat polygonal-shaped with outward bulges along the edge, most notably to the west. The inner walls have a terrace system and the interior is somewhat rough and irregular. The central peak lies just to the north of the midpoint, and extends in a northerly direction.

The lava-flooded formation C. Mayer D is attached to the southeastern rim of the crater, and a gap in the southeastern rim joins it to the Mare Frigoris. Thus the lunar mare extends up to the outer rampart of C. Mayer.[6]: 13 

This crater is named after the Moravian astronomer and teacher Christian Mayer (1719-1783).[1] His name was added to lunar nomenclature by German astronomer Johann H. Schröter in 1791.[7] Its designation was adopted by the International Astronomical Union in 1935.[1]

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 C. Mayer.[8] (See the C Mayer D crater that is very similar in shape to the map of Brazil). >> [(pt:C. Mayer D (Cratera) )]

C. Mayer[6]: 294  Latitude Longitude Diameter
B 60.2° N 15.6° E 36 km

The satellite features F and H include permanently shadowed regions where the sunlight never reaches.[9]
