English: Concentric crater Archytas G (bigger one) and a smaller unnamed crater, also with signs of concentricity, on the Moon, in Mare Frigoris, on an intrusive dome (look Wöhler & Lena, 2009). Diameter of Archytas G is 7.3 km. It is number 1 in the list of concentric craters by Wood, 1978 (the smaller one is not included). Photo by Lunar Reconnaissance Orbiter, made with Narrow Angle Camera on 3 January 2013 from altitude 156 km. Sun elevation is 11.0°. Width of the photo is 16×13.5 km, north is approximately up (to make it precisely on the top, the image must be rotated 2.4° cw, but if so, good cropping would be impossible).
