Eponym	Wilhelm C. Röntgen

Röntgen is a relatively large lunar impact crater that lies along the northwestern limb of the Moon. The northwestern outer rim is partly overlaid by Nernst crater. Both Nernst and Röntgen overlay the eastern rim of the much larger Lorentz walled plain. The smaller crater Aston is only separated from the eastern edge of Röntgen by a few kilometers of terrain. To the south-southeast is Voskresenskiy crater.

The outer rim of Röntgen has been heavily eroded by subsequent impacts, and it now forms an uneven, jumbled ring of ridges in the surface. There is a relatively fresh, cup-shaped crater along the common rim between Röntgen and Nernst. The interior floor of Röntgen is nearly level, with only a few patches of uneven terrain near the edges and a low ridge near the mid-point. The surface of the floor is marked by a few small and several tiny craterlets.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Röntgen crater.
