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.
Tir Planitia is a large plain on the planet Mercury. The name Tir (تیر) is the Persian word for "Mercury",, and the name was approved in 1976. It was first observed in detail by Mariner 10. It lies between the large crater Mozart and the ancient Tolstoj basin.
Kuiper is a moderate-size crater with a central peak cluster located at 11.35°S 31.23°W on Mercury. It is 62 kilometers in diameter and was named after Dutch-American astronomer Gerard Kuiper in 1976. It is one of only 2 Mercurian craters which are named not after artists, and one of very few cases when the same name is used for 3 craters. Gerard Kuiper, being a leader of American planetary science, died shortly before the first images of Mercurian surface were made.
Bach is a double-ringed impact basin within the Bach quadrangle of Mercury. It was named by the IAU in 1976.
Michelangelo is a 230 km diameter impact basin in the Michelangelo quadrangle of Mercury, which is named after this crater. The crater itself was named by the IAU in 1979 after the Italian painter, sculptor and architect Michelangelo.
Vivaldi is a crater on Mercury. It was named by the IAU after Italian composer Antonio Vivaldi in 1976. It has a prominent and nearly continuous inner ring whose diameter measures about half that of the outer ring. It is one of 110 peak ring basins on Mercury. Unlike some of the lunar multiringed structures, no vestiges of additional rings are apparent around this crater. It is classified as c3 age.
Mozart is a crater on Mercury, named by the IAU in 1976 after Austrian composer Wolfgang Amadeus Mozart.
Munkácsy, named after Mihály Munkácsy, is a crater on Mercury. Munkácsy originally had a double-ring basin structure, but most of the inner ring was buried when the basin was flooded with volcanic lava. Only a few remnants of the ring poke up through the lava, although low ridges in the lava seem to trace out much of the rest of the ring's circumference. Munkácsy is one of 110 peak ring basins on Mercury.
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.
Rachmaninoff is an impact crater on Mercury. This basin, first imaged in its entirety during MESSENGER's third Mercury flyby, was quickly identified as a feature of high scientific interest, because of its fresh appearance, its distinctively colored interior plains, and the extensional troughs on its floor. The morphology of Rachmaninoff is similar to that of Raditladi, which is one of the youngest impact basins on Mercury. The age of Raditladi is estimated at one billion years. Rachmaninoff appears to be only slightly older.
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.
Balzac is a crater on Mercury. Its name was adopted by the International Astronomical Union in 1976. Balzac is named for the French writer Honoré de Balzac, who lived from 1799 to 1850.
Bartók is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1979. Bartók is named for the Hungarian composer Béla Bartók, who lived from 1881 to 1945.
Bernini is a crater on Mercury. It has a diameter of 146 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Bernini is named for the Italian architect and sculptor Gian Lorenzo Bernini, who lived from 1598 to 1680.
Cervantes is a crater on Mercury. It has a diameter of 181 kilometers. Its name was adopted by the International Astronomical Union in 1976. Cervantes is named for the Spanish writer Miguel de Cervantes, who lived from 1547 to 1616.
Mark Twain is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1976. Mark Twain is named for the American author Mark Twain, who lived from 1835 to 1910.
Holst is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) on April 24, 2012.
Seuss is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 2012. It is named for the American author and cartoonist Theodor Seuss Geisel, better known as Dr. Seuss.
Wang Meng is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1976. The crater is named for the Chinese painter Wang Meng.
