Named after Aśvaghosa - Indian philosopher and poet (fl. A.D. 80-150).
Aśvaghosa is an impact crater on Mercury, 90 kilometers in diameter. It is a nearly circular formation, and its rim remains intact, except where it is broken at its southern side, and at its northern side by an indentation from two conjoined craterlets. On the crater floor is a central mountain that rises to multiple peaks. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On Mercury they are named after deceased artists, musicians, painters, and authors who have made outstanding or fundamental contributions to their field and have been recognized as art historically significant figures for more than 50 years.
