Koch is a 95 km crater on the far side of the Moon and located in the center of our chart Section 150. It lies in the southern hemisphere, to the south-southeast of the walled plain Jules Verne (143 km wide and on the NW edge of the section). Attached to the northeastern rim of Koch by a neck of uneven terrain is the crater Lundmark. Less than one crater diameter to the south of Koch is Crocco. This crater has a worn and eroded outer rim. Several small craters lie along the outer rim, particularly along the northern edge. Attached to the western side is the satellite crater Koch U. The interior floor is also marked by some small craters, with a pair located just to the north of the midpoint and another along the southern inner wall.  Jules Verne is named after the French author and is straddling four sections (139, 140, 149, 150). Most of the interior floor of this crater has been flooded with basaltic lava, leaving a dark, low-albedo surface that is relatively level and flat. It is somewhat unusual for a crater feature on the far side to be flooded with lava, as the crust is generally thicker than on the near side. However this crater is located entirely within the South Pole-Aitken-basin. The outer rim of Jules Verne is worn and eroded, with several craters lying across the edge.
