Hanno (crater) : ウィキペディア英語版 | Hanno (crater)
Hanno is a lunar crater that lies near the southeastern limb of the Moon, along the western edge of the Mare Australe. About a crater diameter to the southwest is the prominent crater Pontécoulant. This is a heavily worn crater formation with an outer rim that has been battered and pock-marked by small impacts. A small crater attached to the north-northeastern rim forms a depression in the side. The inner walls are nearly featureless except for a few small craterlets, and the interior floor is likewise level and battered by tiny craters. ==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 Hanno.
