BRIEF DESCRIPTION
20.2_S_149.2_E
Gararin is a large, 265 km, lunar impact crater located in the southern hemisphere on the lunar Far Side.  A fantastic graphic representation of Gagarin can be observed in the Lunar Orbiter Laser Altimeter (LOLA images).  To the southwest is the crater Pavlov (out of frame) and to the northeast lies Keeler. Closer to the rim are the craters Levi-Civita to the southwest, and Beijerinck to the north-northeast, all out-of-frame. Isaev lies entirely within the northwest rim of Gagarin. In contrast with the floor of Gagarin, Isaev has a floor with a somewhat low albedo. Isaev steals the interest in the region with most of the links devoted to it and is the largest of six craters falling within the perimeter of Gagarin that have been named after pioneers of Russian aviation and astronautics. Gagarin has been heavily eroded by a long history of crater impacts. The worn rim forms a low, circular ridge around the somewhat bowl-shaped interior. The inner floor is covered by a multitude of crater impacts of various dimensions. Little if anything remains of a central ridge, if the crater ever possessed such a feature. (Credit: Some of the information used in the section feature descriptions was obtained from Wikipedia.org. Section 128 and this directory was created by Fran Ridge and Ned Haskin of The Lunascan Project).
