Chappell (crater)
Encyclopedia
Chappell is a lunar
crater
that is located on the far side of the Moon
, in the northern hemisphere just to the north of the crater Debye
. This feature is located in a heavily bombarded section of the surface, and much of the outer rim of the crater is overlain by many smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.
In contrast the interior floor is not notably marked by impacts except for a few tiny craterlets. The interior surface is more level and featureless compared to the rugged terrain that surrounds the crater. Near the mid-point of the floor is a low, rounded central ridge.
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...

Debye (crater)
Debye is a lunar crater that is located in the northern hemisphere on the Moon's far side, as seen from the Earth. It lies to the south of the crater Chappell, and to the southwest of the walled plain Rowland....
