Gullstrand (crater)
Encyclopedia
Gullstrand is a lunar
impact crater
that lies on the northern hemisphere
on the Moon
's far side. About one crater diameter to the southeast is the larger crater Perrine
. To the west-southwest is Quetelet
.
This crater has a circular rim that is relatively well-defined, and has only been moderately worn. A small, bell-shaped crater forms a break through the rim to the southwest, and a small craterlet is attached to the southeastern side along the rim of Gullstrand. An oddly shaped small crater feature is attached to the eastern edge. There are also tiny craters along the rim of Gullstrand along the northern and southern edges.
The inner walls of Gullstrand are relatively simple and featureless, and the interior floor is not marked by any craters of note. There is a low central ridge at the mid-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...

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...

Perrine (crater)
Perrine is a lunar crater that is located on the northern hemisphere on the far side of the Moon. It lies to the west of the large walled plain Landau, and to the northeast of the crater Charlier. To the north-northwest is the smaller Gullstrand....

Quetelet (crater)
Quetelet is a lunar crater that lies in the Moon's northern hemisphere, on the far side from the Earth. It lies to the southeast of the crater Schlesinger, and to the east of Von Zeipel. To the east of Quetelet is Perrine....
