Olivier (crater)
Encyclopedia
Olivier is an old, eroded crater
that is located in the northern hemisphere
on the far side of the Moon
. It lies in a region of dense cratering on all sides. To the east-southeast is a younger but comparably sized crater named Störmer
. Southwest of Olivier is the crater Volterra
.
The southern rim of Olivier is covered by an unusual formation of small craters that lie adjacent to each other and have almost completely obliterated the rim. These form a line from the southwest rim to the east-southeast. Several other craters lie across the rim of Olivier, most notably a crater cutting across the northern rim and several smaller craters in the eastern rim. The remainder of the rim is worn and eroded, so that the features have become rounded and somewhat irregular.
In comparison to the rim, the interior floor is nearly flat and smooth. The most notable impact is a small craterlet near the northern rim. There are a few tiny craterlets scattered about, but nothing of significance. The crater lacks a central peak, and the only irregularities alie along the edge of the inner wall.
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...

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...

Störmer (crater)
Störmer is a lunar impact crater that is located on the far side of the Moon from the Earth, named after Carl Størmer, a Norwegian mathematician and aurora researcher...

Volterra (crater)
Volterra is a lunar crater that is located in the northern latitudes on the far side of the Moon. To the northeast is the crater Olivier, and to the south-southwest lies von Békésy. This is an eroded crater formation, particularly along the western side where the rim is more uneven. A small crater...
