Nunn (crater)
Encyclopedia
Nunn is a lunar
impact crater
that is located just beyond the eastern limb of the Moon
, along the northern edge of Mare Smythii
. To the east of this crater is the much larger Babcock
, and to the northwest is Jansky
.
This is a circular, bowl-shaped crater with some impact wear along the northwestern rim and to a lesser degree along the southeastern edge. The remainder of the crater perimeter is relatively free of erosion, and the edge is well-defined. The darker-hued interior floor is about half the crater diameter, and is level and almost featureless.
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...

Mare Smythii
Mare Smythii is a lunar mare located along the equator on the easternmost edge of the lunar near side. The Smythii basin where the mare is located is of the Pre-Nectarian epoch, while the surrounding features are of the Nectarian system...

Babcock (crater)
Babcock is a lunar crater that is located on the far side of the Moon. It lies on the northeastern edge of Mare Smythii, to the southeast of Mare Marginis. To the south of Babcock is the crater Purkynĕ, and to the east-northeast lies Erro...

Jansky (crater)
Jansky is a lunar impact crater that lies along the eastern limb of the Moon. It lies due east of the larger walled plain Neper, along the southern edge of the Mare Marginis. Due to its location, this crater is viewed from the side from Earth, limiting the amount of detail that can be observed...
