Sibelius is a crater on Mercury.[1] It has a diameter of 94 kilometres (58 miles). Its name was adopted by the International Astronomical Union (IAU) in 1985. Sibelius is named for the Finnish composer Jean Sibelius.[2]
Sibelius has a complex central peak that is offset from the center to the southwest. Within the central peak complex is a dark spot of low reflectance material (LRM), closely associated with hollows.[3]
To the south of Sibelius is the crater Vincente, and to the east are Delacroix and Shelley.
