Marth (lunar crater) : ウィキペディア英語版 | Marth (lunar crater)
Marth is a small lunar crater located in the northwest part of the Palus Epidemiarum. To the northwest is the crater Dunthorne, and to the southwest lies Ramsden. This feature lies in a system of rilles named the Rimae Ramsden, and an interrupted branch passes only a few kilometers to the south of the rim. Marth is unusual for having a double rim, with a smaller inner crater concentric to the outer rim. The smaller crater is located near the center of the larger rim, giving the feature a bullseye appearance. ==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 Marth.
