BRIEF DESCRIPTION
13.8_S_179.8_W
Racah is Ridge Section 131 and titled after the 63 km lunar impact crater on the Far Side of the Moon. It lies almost due south of the larger crater Daedalus (Section 120), and lies across lunar longitude 180W, i.e. the longitude that is diametrically opposite to the Earth. To the west-southwest of Racah is the crater Aitken, which straddles Sections 130-131, and to the southeast lies De Vries (Section 142). The rim of Racah is eroded and is not quite circular, having a prominent outward bulge along the west-northwest side. The edge is somewhat damaged along the southern rim, but no significant craters lie along the side. The interior floor is uneven in places with some small impacts. This feature is named after the Israeli physicist Giulio Racah. There were a large number of "hits" for images of this area, both by Lunar Orbiter and by the Apollo missions, probably due to the already high interest paid to Daedalus (Section120)  (Credit: Some of the information used in the section feature descriptions was obtained from wikipedia.org. Section 131 and this directory was created by Fran Ridge and Ned Haskin of The Lunascan Project).
