Carolan is a crater on Mercury. Its name was suggested by an Irishman, Fergal Donnelly, and two Americans, Joseph Brusseau and Deane Morrison, in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015. [1] Carolan is named for the Irish composer and performer Turlough O'Carolan, who lived from 1670 to 1738 C.E. [2] The craters Kulthum, Enheduanna, Karsh, and Rivera were also named as part of the contest.
S band radar data from the Arecibo Observatory collected between 1999 and 2005 indicates a radar-bright area along the southern interior of Carolan, which is probably indicative of a water ice deposit, and lies within the permanently shadowed part of the crater. [3] MESSENGER's Mercury Laser Altimeter (MLA) was used to measure surface reflectance of the surface of the planet, and the radar-bright material is covered by low-reflectance material. [4]
Carolan lies to the southwest of the large crater Prokofiev.
