Epigenes (crater)
Encyclopedia
Epigenes is a lunar
crater
that is located in the north part of the Moon
, and is sufficiently close to the northern limb to appear significantly foreshortened from the Earth
. It lies just to the northwest of the remains of the walled plain W. Bond
. Due north of Epigenes is Goldschmidt
, and the ruined crater Birmingham
lies just to the southwest.
This formation is a picture in contrasts. The north and northwest parts of the rim are well-formed with little appearance of wear, while the remainder of the rim is notably eroded, particularly in the east-southeastern half. The western half of the interior floor is smooth and nearly featureless, while the remainder is somewhat hummocky and appears covered in ejecta
from the east. The small crater Epigenes B intrudes into the northeastern rim.

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...

W. Bond (crater)
W. Bond is an irregularly shaped lunar walled plain that is located in the northern part of the Moon, to the north of the Mare Frigoris. It lies to the east of the crater Birmingham, and south-southwest of Barrow. Epigenes is located just to the northwest of the outer rim. Along the southwest edge,...

Goldschmidt (crater)
Goldschmidt is a large lunar crater of the variety commonly termed a walled plain. It lies in the northern part of the Moon's near side, and appears oval in shape due to foreshortening. The rim is actually relatively circular, although the western rim is overlain by the prominent crater Anaxagoras...
