        Vieta (87 km) is a lunar impact crater that lies north of Schickard, in the south-west of the Moon. In the southeast is Fourier (52 km) below, and north-north-east lies Cavendish (56 km).
        The outer edge of this crater has undergone erosion and small craters are on edge. The interior walls are irregular, and broken in some locations. A chain of small craters are located on the northern half of the bottom of the crater, on a line east-northeast.
    The crater was named after François Viète (latin: Franciscus Vieta, 1540-23 Feb 1603), which was a French mathematician who made an important step towards modern algebra, thanks to its innovative use of letters as parameters in the equations.

        Fourier (52 km). With the exception of the north-west outer edge,it is strongly eroded.
Fourier B (11 km), asatellite crater, lies along the eastern edge. The inner wall is big. The interior is less than half the diameter of the crater rim.
    The crater was named after Jean Baptiste Joseph Fourier (March 21 1768 - 16 May 1830), which was a French mathematician and physicist best known for heat transfer problems and vibration.

        Cavendish (56 km), small craters are between Henry (41 km) north-west and Gasparis (30 km) east-southeast.
Crater rim is strongly affected. Cavendish E (24 km), lies on the south-west. Cavendish A (10 km), is lower on the north-est.A"rivulet" of Gasparis reach the eastern edge of Cavendish.
    The crater was named after Henry Cavendish (10 October 1731-24 Feb 1810) which was a British scientist noted for his discovery of hydrogen or what he called "inflammable air."

        Mersenius (84 km), is a lunar crater that is located west of Mare Humorum, in the south-west of the Moon. To the south-west of the crater is Mersenius is Cavendish, and south-east Liebig (37 km). Mersenius is 84 kilometers in diameter and 2.3 kilometers deep. It dates from Nectarian age  3.92 - 3.85 billion years ago.
    The crater is named after the French philosopher and physicist Marin Mersenne who lived in the 17th century.
