Lippmann is Ridge Section 163 named after the large, 160 km-wide lunar impact crater in the southern part of the lunar Far Side.  Quite a bit of difference in the two views above due to the LRO angle in our chart verses the USGS with more libration. Just to the northeast is the walled plain Mendel (not well-delineated in the LRO shot), only slightly smaller than Lippmann. To the south-southeast lies the crater Petzval (out of frame). As with many lunar formations of this size, Lippmann has been eroded by subsequent impacts. The southeastern part of the rim has been overlain by the satellite crater Lippmann L, which in turn has become worn and eroded. The relatively fresh crater Lippmann Q lies across the southwest rim. The remaining rim has become worn and rounded, with a few surviving terrace-like features and the rim edge having lost their definition. The western and eastern sides of the crater in particular are nearly overlain by ejecta material. The interior floor is relatively level, at least in the western two-thirds, but is marked by several impacts. The most notable of these is Lippmann P, located just to the southwest of the midpoint. A short chain of small craterlets lies along the southern part of the floor. The remainder is marked by a few small craterlets and pitted by tiny craters. The terrain to the north and east of this crater are streaked with features that are radial to the huge Mare Imbrium impact basin to the northeast.
