lunar impact crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact crater ...

Jules Verne. Farther to the east of Seidel is the western edge of
Mare Ingenii
Mare Ingenii (Latin ''ingeniī'', the "Sea of Cleverness") is one of the few lunar mare features on the far side of the Moon. The mare sits in the Ingenii basin, which is of the Pre-Nectarian epoch, which lies in turn in the outer part of the ol ...
, and to the northeast lies the crater
O'Day.
This is an eroded crater with a small crater overlying the south-southeastern outer rim. The southern rim is overlain by material deposits, most likely ejecta from another impact. The remainder of the rim has survived fairly well, and is marked only by tiny craterlets and general wear. The interior floor is relatively level with a few tiny craterlets marking the surface.
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 Seidel.
