Röntgen (crater)
Encyclopedia
Röntgen is a relatively large lunar
impact crater
that lies along the northwestern limb of the Moon
. Its northwestern outer rim is partly overlain by the crater Nernst
. Both Nernst and Röntgen overlie the eastern rim of the much larger walled plain Lorentz
. The smaller crater Aston
is separated from the eastern edge of Röntgen by only a few kilometers of terrain. To the south-southeast is Voskresenskiy
.
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.
Moon
The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...
impact crater
Impact crater
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Nernst (crater)
Nernst is a lunar impact crater that lies on the far side of the Moon, just beyond the northwestern limb. It lies across the northern part of the larger walled plain Lorentz, and intrudes slightly into the northwestern rim of the crater Röntgen....

Lorentz (crater)
Lorentz is a huge lunar crater that lies just beyond the northwest limb of the Moon, in a region that is brought into sight of the Earth during favorable librations. This formation is nearly as large as the Mare Nectaris on the near side of the Moon, although it has not been submerged by lava as...
. The smaller crater Aston
Aston (crater)
Aston is a lunar impact crater that is located along the northwest limb of the Moon. Because of its location the crater is seen nearly from on edge, and visibility is subject to libration. It lies to the east of the crater Röntgen, some distance due west of Ulugh Beigh on the edge of the Oceanus...

Voskresenskiy (crater)
Voskresenskiy is a lunar crater that is located near the western limb of the Moon. Due to its position, this crater is viewed edge-on, limiting the amount of detail that can be viewed...

Satellite craters
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.| Röntgen | Latitude | Longitude | Diameter |
