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]

Degas is a rayed crater on Mercury at latitude 37.5 N, longitude 127 W. Its diameter is 54 kilometres (34 mi). It was named after the French impressionist painter Edgar Degas in 1979. The rays consist of light colored material blasted out during the crater's formation. Craters older than Degas are covered by the ray material, while younger craters are seen superimposed on the rays. Degas forms a crater pair with Brontë to the north. Both lie near the center of Sobkou Planitia.

Rodin is an impact crater on the planet Mercury, 230 kilometers in diameter. The rim is even and circular, except where it is broken in two places toward the north and south. It is named for the French sculptor Auguste Rodin. Its name was approved by the International Astronomical Union in 1976.

Homer is a crater on Mercury. It is one of 110 peak ring basins on Mercury. It is Tolstojan in age.

Hokusai is a rayed impact crater on Mercury, which was discovered in 1991 by ground-based radar observations conducted at Goldstone Observatory. The crater was initially known as feature B. Its appearance was so dissimilar to other impact craters that it was once thought to be a shield volcano. However, improved radar images by the Arecibo Observatory obtained later in 2000–2005 clearly showed that feature B is an impact crater with an extensive ray system. The bright appearance of rays in the radio images indicates that the crater is geologically young; fresh impact ejecta has a rough surface, which leads to strong scattering of radio waves.

Derain is a crater on Mercury named after André Derain, a French artist, painter, sculptor and co-founder of Fauvism with Henri Matisse. It has uncommonly dark material within and surrounding the crater. The material is darker than the neighboring terrain such that this crater is easily identified even in a distant global image of Mercury. The dark halo may be material with a mineralogical composition different from the majority of Mercury's visible surface. Craters with similar dark material on or near their rims were seen on the floor of the Caloris basin during MESSENGER’s first flyby.
