Vieta (crater)
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.
==Satellite craters==
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Vieta.
