Vieta (crater)
Encyclopedia
Vieta is a lunar
impact crater
that lies due north of the walled plain Schickard
, in the southwestern part of the Moon
. About half a crater diameter to the southeast is the smaller Fourier
, and to the north-northeast lies Cavendish
.
The outer rim of this crater has undergone some impact erosion, and small craters lie along the northeast, south, and north-northwestern sides. The inner walls are irregular, with incised bases in some locations. A chain of small craters lies across the northern half of the interior floor, following a line towards the east-northeast. The floor is nearly level, but with some uneven areas in the south and by the crater chain.
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...

Schickard (crater)
Schickard is a lunar impact crater of the form called a walled plain. It lies in the southwest sector of the Moon, near the lunar limb. As a result the crater appears oblong due to foreshortening. Attached to the northern rim is the lesser crater Lehmann, and to the northeast is the even smaller...

Fourier (crater)
Fourier is a lunar crater that is located in the southwestern part of the Moon's near side, just to the southeast of the crater Vieta. To the northeast is the Mare Humorum. The rim of this crater is roughly circular, but appears oval when viewed from the Earth due to foreshortening.Except to the...

Cavendish (crater)
Cavendish is a lunar crater that is located in the southwest part of the Moon, to the southwest of the larger crater Mersenius. It lies between the smaller craters Henry to the west-northwest and de Gasparis to the east-southeast....
