Sinan (Mercury)

Named after Joseph Sinan - Turkish architect (1489-1588).

Sinan is an impact crater on the planet Mercury, 147 kilometers in diameter. It has one craterlet on the south-southwestern side of the crater floor, and it has a symmetrical pit slightly west of the center. Together with a smaller unnamed crater on its southern border, the crater Sinan forms a shape similar to that of the spade found in card games. (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.
