Mariotte is an elongated 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...

 that is located on the far side of the Moon

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...

. This formation is located about one crater diameter to the southwest of the smaller Das

Das (crater)

Das is a lunar impact crater on the far side of the Moon. It is located to the northwest of the walled plain Chebyshev. To the southwest of Das is the irregular crater Mariotte, and Von der Pahlen lies to the east-northeast....

. This crater is longer to the southeast by about an extra 5 km, giving this feature an egg-shaped outline. The outer rim is sharp-edged and little eroded. The interior floor is uneven, particularly toward the southeastern end. To the southeast of Mariotte is the large crater Chebyshev

Chebyshev (crater)

Chebyshev is a large lunar crater that lies in the southern hemisphere on the far side of the Moon. The somewhat smaller crater Langmuir is intruding into the east-southeastern rim of Chebyshev, forming a chain of large craters with Brouwer on Langmuir's eastern rim.The outer rim of this walled...

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 Mariotte.

• Mariotte Y — See Murakami
  Murakami (crater)
  Murakami is an impact crater on the far side of the Moon. To the south-southeast is the crater Mariotte. Murakami partly overlaps the western rim of the satellite crater Mariotte Z. To the southeast of Murakami, and to the northeast of Mariotte, is the smaller crater Das. This is a roughly...
