Back (crater)

Back is a lunar impact crater that lies on the far side of the Moon. It is located to the northeast of the prominent crater Tsiolkovskiy, and west of the Mare Moscoviense.

The rim of Back is somewhat eroded, with smaller craters lying across the eastern and southern edges. The interior floor is relatively level, but it is marked by several small craterlets. The most notable of these is a small crater located just to the northeast of the crater's midpoint.

Back is named after Ernst Emil Alexander Back, a German physicist.

Adjacent to the southwest rim of Back is the slightly smaller crater Wyld. Farther to the southeast lies the crater Neujmin.
