Geological Chronicle

Bose is on the Moon's far side in the southern hemisphere. The Bose-Bhabha pair lie in the center region of the South Pole-Aitken basin floor, with Bose northwest of Bhabha and southeast of Alder. Its diameter is 92.55 kilometers.

The rim dates to the Early Imbrian epoch. Impacts have worn its outer edge, though the wall's shape remains well-preserved. The small satellite crater Bose D crosses the east-northeastern rim, and a smaller craterlet lies on the inner southeast wall.

The floor is level, with a low central peak offset slightly southeast of the midpoint. The floor is likely basalt, significantly covered by ejecta from nearby impacts. The peak's spectra fit an olivine-bearing gabbroic norite mineralogy, originating at a depth of 9.1 to 14.5 km.

The crater is named for Indian botanist and physicist Jagadis Chandra Bose (1858 to 1937), for his work on wireless communication. The International Astronomical Union officially adopted the designation in 1970.

Chronology & Exploration

1. Early Imbrian Rim dates to Early Imbrian

   The rim dates to the Early Imbrian epoch of the lunar geologic timescale.

2. Undated Impacts wear the rim

   Impacts have worn the outer rim and rounded its edges, while the wall's shape remains well-preserved.

3. Undated Central peak spectra

   The peak's spectra fit an olivine-bearing gabbroic norite mineralogy, originating at a depth of 9.1 to 14.5 km.

4. 1970 Designation adopted

   The International Astronomical Union officially adopted the crater's designation.
