Euctemon (crater)
Encyclopedia
Euctemon is a lunar
crater
that is located in the northern part of the Moon
, along the northwest rim of the crater Baillaud
. To the southwest of Euctemon is the large walled plain Meton
, and to the north-northeast lies the crater De Sitter
. Due to its location, Euctemon appears foreshortened when viewed from the Earth
.
The interior floor of this crater has been resurfaced some time following the original formation, leaving a nearly level, featureless plain surrounded by the worn outer rim. This floor is marked only by a number of tiny craterlets, and the small crater Euctemon K near the southwest inner wall. A small crater has cut through the western rim, and has joined with the main crater by a gap in its eastern rim. The two craters now share a common floor. Just to the north is another small crater, Euctemon H, that now forms a wide cleft through the rim. Along the ridge that separates Euctemon from Baillaud is perched the small crater Euctemon N.

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...

Baillaud (crater)
Baillaud is a lunar crater that is located near the north limb of the Moon. The rim of the crater has been eroded and worn by a long history of impacts, leaving a hilly ridge surrounding the interior. The crater Euctemon is intruding into the rim to the northeast, and the rim bulges outward to the...

Meton (crater)
Meton is a compound formation on the Moon that consists of several merged crater rings that have been flooded with lava, forming the remnant of a walled plain in the shape of a clover leaf. It is located near the northern lunar lumb, and is viewed from a low angle and foreshortened. The crater...

De Sitter (crater)
De Sitter is a lunar crater that is located near the northern limb of the Moon, to the north of the Baillaud–Euctemon crater pair. Due to its location, this crater appears very foreshortened when viewed from the Earth, limiting the detail that can be viewed...
