Casatus (crater)
Encyclopedia
Casatus is a lunar
impact crater
that is located near the southern limb of the Moon
. The north-northeast rim of the crater overlies a portion of the slightly larger crater Klaproth
. Along the western rim, Casatus A intrudes somewhat into the interior, producing an inward-bowing rim. To the southeast of Casatus is Newton
.
The outer rim of Casatus is old and worn, with many tiny impacts along the rim and inner wall. The small satellite crater Casatus J lies across the south-southeastern rim. The height of the rim is lower where it divides this crater from Klaproth, forming a rounded ridge.
The interior floor is a nearly level surface marked by several tiny ghost-crater
rims projecting above the surface and a pair of clefts in the southern part of the floor. A small, bowl-shaped impact crater forms a prominent feature in the northern half of the floor. There is no central peak formation at or near the mid-point of the interior.
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...

Klaproth (crater)
Klaproth is an old lunar crater that lies in the rugged southern highlands of the Moon's near side. Due to its location, this crater appears significantly foreshortened when viewed from the Earth...

Newton (lunar crater)
Newton is a lunar crater located near the south limb of the Moon. It is south-southwest of the crater Moretus. To the northeast is Short, and in the northeast are Casatus and Klaproth. Because of its location, the crater appears highly oblong due to foreshortening. It is considered the deepest...

Palimpsest
A palimpsest is a manuscript page from a scroll or book from which the text has been scraped off and which can be used again. The word "palimpsest" comes through Latin palimpsēstus from Ancient Greek παλίμψηστος originally compounded from πάλιν and ψάω literally meaning “scraped...
