Named after Mikhail Yurevich Lermontov - Russian poet (1814-1841).
Lermontov is an impact crater on the planet Mercury, 152 kilometers in diameter. It has a circular rim and a flat crater floor. Lermontov is likely a mature crater, but it remains a bright feature because of low opaque material on its floor. (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.
