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

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...

. It lies less than a crater diameter to the east-southeast of the larger crater Langemak

Langemak (crater)

Langemak is a prominent impact crater on the far side of the Moon. It is located less than one crater diameter west-northwest of Danjon, and nearly due east of Meitner. To the southwest of Langemak is Kondratyuk. Langemak partly overlies the larger and older crater Langemak N...

. To the east-northeast of Danjon is the crater Perepelkin

Perepelkin (lunar crater)

Perepelkin is a lunar impact crater that is located just to the south of the similar crater Love. Attached to the exterior of its southern rim is the smaller Shirakatsi...

, and due south lies the walled plain Fermi

Fermi (crater)

Fermi is a large lunar crater of the category named a walled plain. It lies on the far side of the Moon and can not be viewed from the Earth. Thus this feature must be viewed from an orbiting spacecraft....

.

The northeastern rim of Danjon is overlain by the smaller crater D'Arsonval

D'Arsonval (crater)

D'Arsonval is a small lunar impact crater on the far side of the Moon. It is situated across the northeastern rim of the older and larger crater Danjon. To the west of D'Arsonval is Perepelkin....

. Danjon overlies the southeastern corner of the slightly smaller satellite crater Danjon X. The outer rim of this crater is worn and eroded, particularly at the southern end, and the interior floor is irregular and marked by several small craterlets.

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 Danjon.
