Van de Graaff is a crater formation located on the far side of the Moon, on the northeast edge of Mare Ingenii. The crater is named for physicist Robert J. Van de Graaff, whose groundbreaking work includes the invention of the Van de Graaff generator. [1] Van de Graaff is one of the largest craters of Nectarian age. [2]

Birkeland is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon. This crater is attached to the central waist of the oddly shaped Van de Graaff crater formation, and may partly account for that crater's figure-8 shape. To the southeast is the large walled plain Leibnitz.
Prior to formal naming in 1961 by the IAU, [1] the crater was known as Basin XIV. [3] Mare Ingenii is located at the antipode of the Mare Imbrium impact basin. The furrowed crater walls of the basin (and possibly those of Van de Graaff crater) may have been caused by focused seismic waves resulting from the Imbrium impact. [4]
At the region of the Moon's surface exactly opposite Imbrium Basin, there is a region of chaotic terrain (the crater Van de Graaff) which is thought to have been formed when the seismic waves of the impact were focused there after travelling through the Moon's interior. Mare Imbrium is about 750 miles (1,210 km) wide.
Van de Graaff died on January 16, 1967, in Boston, Massachusetts. His wife died in 1972. In the year that he died, the progressive rock band Van der Graaf Generator was formed, named after him, notwithstanding the spelling errors. The Van de Graaff crater on the far side of the Moon is named after him.

Nassau is a lunar impact crater on the Moon's far side. It abuts against the northeastern rim of the figure-8-shaped crater Van de Graaff. To the southeast of Nassau lies the crater Leeuwenhoek, and to the east is Orlov.
