Dominici is a crater on Mercury. Dominici’s bright rays indicate that it is young, and the young rays appear light blue in enhanced-color images. Dominici also has bright material on its floor and is surrounded by crater ejecta and material that appears orange in enhanced color. These color differences, as in nearby Titian crater, suggest that the impact crater excavated material from beneath Mercury’s surface that differs in composition from the surrounding surface.

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.
