Eponym | Leonid I. Mandelʹshtam |
The outer rim of this crater has been battered into near ruin, with sections forming only an irregular circular rise in the surface. Much of the rim consists of clefts, small craters, and ridges. The satellite crater Mandelʹshtam R breaks across the rim to the west-southwest, and Mandelʹshtam Y is attached to the northern edge.
The interior floor of the crater has not escaped bombardment, and the central portion is overlain by Mandelʹshtam A, a respectable crater in its own right. Mandelʹshtam N lies on the interior along the south-southwestern inner edge. The northwestern floor and to a lesser degree the southeast floor are relatively level, and have suffered less impact damage than elsewhere.
The crater was named after Dutch geophysicist and geodesist Leonid I. Mandelʹshtam by the IAU in 1970.[1] Mandelʹshtam was known as Crater 220 prior to naming.[2]
The small crater Mandelʹshtam F to the east has a small ray system with several faint, streaky rays overlaying the floor of Mandelʹshtam.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Mandelʹshtam.
