Fourier crater (51 km), has a quite large depth of 3.7 km, compared to its size. It is located on the south-west of the Moon, to the southeast of the larger crater Vieta.
The crater is generally circular, but appears to be oval when viewed from Earth because it is located on the edge of the lunar disk.
The name of the crater comes from Jean-Baptiste Joseph Fourier (March 21, 1768 - May 16, 1830), who was a mathematician and physicist born in Auxerre, and was best known for heat transfer and vibration. "Fourier Transform" and "Fourier's law" are also named in his honor. Fourier is also credited for discovering the greenhouse effect.
Vieta (87 km), has a depth of 4.5 km. The outer edge went through erosions of impact and its walls are irregular, with incisions in parts. On the floor is a chain of small craters on the north side.
Crater name comes from François Vieta (Latin: Franciscus Vieta) 1540 - February 23, 1603, a French mathematician whose work on new algebra was an important step towards modern algebra through innovative use as parameters in the equations.

Images were obtained by attaching a camera directly into the eyepiece of an astronomical telescope of 8 inch Newtonian; For this reason the eyepiece visual field was increased.
In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.
