Crater Dollond ( lat. Dollond ) - a small impact crater in the central region of the visible side of the moon . The name was given in honor of the English optician John Dollond (1706-1761) and approved by the International Astronomical Union in 1935.

Crater Description
The immediate neighbors of the crater are Andel Crater in the west; Lindsay Crater in the north-north-west; Tselner Crater in the northeast; Kant crater in the east; Descartes crater in the southeast and Abu l-Fida crater in the south. To the east of the crater is the Sea of Nectar and its Bay of Severity [1] . Selenographic coordinates of the center of the crater , diameter 11 km [2] , depth 2.04 km [3] .
The crater has a circular cup-shaped shape with a small area of a flat bottom, practically not destroyed. The height of the shaft above the surrounding area reaches 410 m [4] ., The volume of the crater is approximately 50 km³ [4] . According to morphological characteristics, the crater belongs to the BIO type (according to the name of a typical representative of this class - the Bio crater).
An area with a significantly larger albedo in relation to the surrounding area is located east of the Dollond Crater. The study of this area with the help of instruments installed on the Clementine probe made it possible to establish that this area is a magnetic anomaly , the most significant on the visible side of the moon. In accordance with modern concepts, this magnetic anomaly deflects particles of the solar wind , preventing the darkening of the constituent rocks from space weathering .
The terrain surrounding the crater was considered to be formed as a result of volcanic eruptions by flows of a more viscous lava compared with the lava that filled the lunar seas . However, analyzes of the samples collected by the Apollo 16 expedition proved that the rocks forming this area are emissions from powerful impacts , most likely from the impact event that formed the Sea of Nectar. The breeds are breccias , their composition is close to the composition of anorthosite gabbro or gabbroid anorthosites.

Spacecraft landing locations
About 50 km northeast of Descartes Crater on April 27, 1972, at the point with selenographic coordinates of 8.97301 ° S. w. 15.49812 ° in. The lunar module Orion of the Apollo 16 expedition landed . The landing area is sometimes called Descartes Highlands.
