Bose (crater)

Bose is a lunar impact crater that is located on the far side of the Moon, in the southern hemisphere.^[3] It lies just to the northwest of the smaller crater Bhabha, and southeast of Alder. The Bose–Bhabha pair lie in the center region of the South Pole-Aitken basin floor.^[2]

The rim of Bose dates to the Early Imbrian epoch of the lunar geologic timescale.^[2] The outer rim has become worn and the edges rounded by impacts, although the shape of the wall is still well-preserved. The small satellite crater Bose D lies across the east-northeastern rim, and a smaller craterlet has impacted on the inner southeast wall.^{[4]: 132–133}

The inner floor is level with a low central peak offset slightly to the southeast of the midpoint. The floor surface is likely basalt that is significantly covered by ejecta from nearby impacts.^[5] There are several tiny craterlets marking the interior, including three to the east of the central peak. The spectra of the central peak fits an olivine-bearing gabbroic norite mineralogy, which originated from a depth of 9.1 to 14.5 km.^[6]

The crater is named after Indian botanist and physicist Jagadish Chandra Bose (1858–1937),^[7] for his works on wireless communication.^[8] Its designation was officially adopted by the International Astronomical Union in 1970.^[1]
