Vivaldi is a crater on Mercury. It was named by the IAU after Italian composer Antonio Vivaldi in 1976. [1] 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. [2] Unlike some of the lunar multiringed structures, no vestiges of additional rings are apparent around this crater. It is classified as c3 age. [3]
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.
Mozart is a crater on Mercury, named by the IAU in 1976 after Austrian composer Wolfgang Amadeus Mozart.
Homer is a crater on Mercury. It is one of 110 peak ring basins on Mercury.
Praxiteles is a crater on Mercury. It is one of 110 peak ring basins on Mercury.
Moody is an impact crater on Mercury.
Raditladi is a large impact crater on Mercury with a diameter of 263 km. Inside its peak ring there is a system of concentric extensional troughs (graben), which are rare surface features on Mercury. The floor of Raditladi is partially covered by relatively light smooth plains, which are thought to be a product of the effusive volcanism. The troughs may also have resulted from volcanic processes under the floor of Raditladi. The basin is relatively young, probably younger than one billion years, with only a few small impact craters on its floor and with well-preserved basin walls and peak-ring structure. It is one of 110 peak ring basins on Mercury.
Izquierdo is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 2009, for the Mexican painter María Izquierdo. The floor of Izquierdo is smooth, the result of having been partially filled with volcanic lava. Circular outlines of the rims of “ghost craters” – smaller, older craters that have been largely buried by the lavas that infilled the basin – are visible in a few places on Izquierdo's floor. The remnants of a buried inner ring are also barely discernible in spots, and it is one of 110 peak ring basins on Mercury. There have been more recent impacts into the floor of Izquierdo, resulting in some small, sharply defined craters.
Scarlatti is a pit-floored crater on Mercury, which was discovered in 1974 by the Mariner 10 spacecraft. It has a prominent peak ring, and it is one of 110 peak ring basins on Mercury. The crater floor is covered by the smooth plains material. The crater displays an arcuate collapse feature along the northeastern peak ring. The size of the pit, which was first noticed in MESSENGER images obtained in January 2008, is 38 × 12 km. Such a feature may have resulted from collapse of a magma chamber underlying the central peak ring complex of the crater. The collapse feature is an analog of Earth's volcanic calderas. Scarlatti is thought to have the same age as the Caloris basin.
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.
Ahmad Baba is a crater on Mercury. It has a diameter of 127 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1979.
Al-Hamadhani is a crater on Mercury. It has a diameter of 186 kilometers. Its name was adopted by the International Astronomical Union in 1979. Al-Hamadhani is named for the Iranian writer Badi' al-Zaman al-Hamadani, who died in 1007 C.E.
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.
Dürer is a crater on Mercury. It has a diameter of 195 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Durer is named for the German artist Albrecht Dürer, who lived from 1471 to 1528.
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.
Alver is a crater on Mercury. It has a diameter of 151.49 kilometers. Its name was adopted by the International Astronomical Union (IAU) on March 15, 2013. Alver is named for the Estonian poet Betti Alver.
