Kulthum is a crater on Mercury. It has a diameter of 31 kilometers. Its name was suggested by Molouk Ba-Isa from Saudi Arabia, Swiss individual Riana Rakotoarimanana, and American residents Yehya Hassouna, David Suttles, Thorayya Said Giovannelli and Matt Giovannelli in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015.[1] Kulthum is named for the Egyptian singer Umm Kulthum.[2]
