Pizzetti (crater)
Encyclopedia
Pizzetti is a partly eroded lunar
impact crater
that lies in the southern hemisphere
on the far side of the Moon
. It is located due north of the similar-dimensioned Clark
, and to the southeast of the large walled plain Milne
. Nearly attached to the western rim is the small Tyndall
. The crater is named for the Italian astronomer and geodesist Paolo Pizzetti (1860-1918).
This crater is generally circular in shape, with the south-southeastern portion of the rim bearing the greatest amount of erosion. There is a slumped shelf along the inner wall to the north and southwest. The interior floor is uneven in places and is marked by several small craterlets.
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...

Sphere
A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point...

Clark (lunar crater)
Clark is a lunar crater that lies in the southern hemisphere of the Moon's far side. It is located midway between the larger walled plain Van der Waals to the south and the similar-sized crater Pizzetti to the north. It is named for American astronomer and telescope maker Alvan Clark and his son...

Tyndall (lunar crater)
Tyndall is a relatively small lunar impact crater on the far side of the Moon, behind the southeastern limb. It is located very near the western outer rim of the larger crater Pizzetti, and the two are separated only by a few kilometers...
