Scarlatti is a pit-floored crater on Mercury, which was discovered in 1974 by Mariner 10 spacecraft. It has a prominent peak ring, which floor is covered by the smooth plain material. The crater displays an arcuate collapse feature along the peak ring. The size of the pit, which was first noticed in MESSENGER images obtained in January 2008, is 38 × 12 km. (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.
