Description
Bhabha lies close to the central regions of the South Pole Aitken Basin (SPA-B) -- a 2500 kilometre-wide basin of the pre-Nectarian period (~ 4.6 to 3.92 bn years) whose centre is approximately at 54.2S, 168.7W. Aged as Nectarian (~ 3.92 to 3.85 bn years), the crater looks relatively fresh with sharp-looking terraced walls all around -- except for its eastern section where the rim has been altered by movement of material (or is it impact-related?). The floor is flat showing signs of a dark-ish material in the south-eastern portion, and the whole inner area is topped off with a series of cental peaks that open towards the north. - JohnMoore2

Additional Information
- Central peak composition: AGN, AN, GN & G (Tompkins & Pieters, 1999)
- Within SPA basin, less than 90% anorthosite in central peak, and 0.1 to 0.6 Maturity Index (not mature) Ohtake and others, 2009
- Ohtake and others, 2009 give a diameter of 78 km; the IAU value (above) differs.
Nomenclature
- Named for Homi Jehangir (1909-1966), an Indian physicist.
- This name was introduced into the IAU nomenclature in the long list of farside names published in Menzel, 1971.
