Aneirin is a crater on Mercury. It has a diameter of 467 kilometers. Its name was adopted by the International Astronomical Union (IAU) on June 13, 2014. Aneirin is named for the Welsh poet Aneirin.[1] Prior to naming, the crater was referred to as b37.[2] It is Tolstojan in age.[3]
Darío crater lies on the western rim of Aneirin. The lobate scarp that cuts across Darío lies along the rim of Aneirin, an unusual situation suggesting that the scarp indicates a zone of weakness extending to a depth of tens of kilometers along the original floor of Aneirin.[2]
