Drygalski

Lat: 79.3°S, Long: 84.9°W, Diam: 149 km, Depth: 5.17 km, Rükl: 72

Left: (Clementine) In this overhead view from space, the irregularly shaped 30-km crater on the rim at 8 o’clock is Drygalski P. Drygalski V is the smaller one inside the rim at 10 o’clock, and extending almost to the floor. None of the other features in this field have IAU-approved names. However, in the southwest (on the lower left), the area of the rim beyond Drygalski P flows without any clear boundary into neighboring Ashbrook.
Right: Tom Bash In this Earth-based view, a favorable libration has brought Drygalski (with its central peak) into view on the Moon's south limb. Because Drygalski is located to the west of the Moon's south pole, a line towards the Moon's north pole is oriented almost horizontally to the left. Hence the image is rotated nearly 90° counter-clockwise relative to the satellite view. Drygalski P can be seen on the main crater's lower right floor. Most of the many craters immediately above Drygalski are unnamed. The half-shadowed 33-km crater at 10-11 o'clock from Drygalski's central peak (with the longer double-peaked shadow on its right) is Le Gentil A with 26-km Wilson C beyond it on the same line. The shadowed filled ellipse in the upper right corner is 108-km diameter Casatus.

Nomenclature

• Named for Erich von Drygalski (February 9, 1865 – January 10, 1949), a German geographer, geophysicist and polar scientist. Between 1882 and 1887, Drygalski studied mathematics and natural science. He graduated with a doctorate thesis about ice shields in Nordic areas. Drygalski led two expeditions between 1891 and 1893, which were supplied by the Society for Geoscience of Berlin. One expedition wintered over in Western Greenland between 1892 and 1893 .
• Name given by Fauth and included in Rectified Lunar Atlas (1963) and approved in IAU Transactions XIIB (1964). According to the report by Arthur, this crater was known as Casatus by Johann Schröter, as Cabeus by Franz, and as Casatus G (Catalog number 3294a) in the original IAU nomenclature of Named Lunar Formations (in which Casatus and Cabeus were used for other features).
