Lermontov is an impact crater on the planet Mercury. The crater is named after Mikhail Yuryevich Lermontov, a 19th-century Russian poet. The name was approved by the International Astronomical Union in 1976.
Tolstoj is a large, ancient impact crater on Mercury. It was named after Leo Tolstoy by the IAU in 1976. The albedo feature Solitudo Maiae appears to be associated with this crater.
The Kuiper quadrangle, located in a heavily cratered region of Mercury, includes the young, 55-km-diameter crater Kuiper, which has the highest albedo recorded on the planet, and the small crater Hun Kal, which is the principal reference point for Mercurian longitude. Impact craters and basins, their numerous secondary craters, and heavily to lightly cratered plains are the characteristic landforms of the region. At least six multiringed basins ranging from 150 km to 440 km in diameter are present. Inasmuch as multiringed basins occur widely on that part of Mercury photographed by Mariner 10, as well as on the Moon and Mars, they offer a potentially valuable basis for comparison between these planetary bodies.
Homer is a crater on Mercury. It is one of 110 peak ring basins on Mercury. It is Tolstojan in age.
Eminescu is a peak ring crater on Mercury 125 kilometers (78 mi) in diameter. Since there are very few later craters superposed on it, Eminescu appears to be a young crater formed around one billion years ago. It has a transitional morphology between larger more complex impact basins like Raditladi and smaller simpler central peak craters.
Bashō is a crater on Mercury named after Matsuo Bashō, a 17th-century Japanese writer. Bashō crater is only 74.62 kilometers (46.37 mi) in diameter, but is a prominent feature on Mercury's surface, due to its bright rays. Photographs from NASA's Mariner 10 and MESSENGER spacecraft show a curious halo of dark material around the crater.
Xiao Zhao crater is small in comparison with many other craters on Mercury. However, Xiao Zhao's long bright rays make it a readily visible feature. The fresh, bright rays, which were created by material ejected outward during the impact event that formed the crater, indicate that Xiao Zhao is a relatively young crater on Mercury's surface.
Atget crater is distinctive on the planet Mercury's surface due to its dark color. Atget crater is located within Caloris basin, near Apollodorus crater and Pantheon Fossae. The dark color of the floor of Atget is in contrast to other craters within Caloris basin that exhibit bright materials on their floors, such as the craters Kertész and Sander. Other craters on Mercury, such as Bashō and Neruda, have halos of dark material but the dark material does not cover the crater floors.
Praxiteles is a crater on Mercury. It is one of 110 peak ring basins on Mercury.
Moody is an impact crater on Mercury.
Amaral is a crater on the planet Mercury. With its smooth floor, surrounding ejecta, and small secondary craters, it appears noticeably younger than the heavily cratered surface around it. Along with a smooth crater floor, Amaral also has a central peak. Bright material on this peak is of particular interest as it appears to have an unusual color. In color-enhanced images, the central peak of Amaral appears as a bright blue color in striking contrast to the otherwise orange tones of surface material nearby. The different color of the central peak likely indicates rocks with different chemical composition from those on the neighboring surface.
Hovnatanian is a crater on Mercury. Its “butterfly” pattern of ejecta rays were created by an impact at an even lower angle than that which formed neighboring Qi Baishi crater. From the "butterfly" pattern of rays, the Hovnatanian impactor was travelling either north-to-south or south-to-north prior to hitting Mercury's surface. Hovnatanian lies to the west of Tir Planitia.
Titian is an impact crater on the planet Mercury. It was named by the IAU in 1976.
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.
Debussy is a rayed impact crater on Mercury, which was discovered in 1969 by low resolution ground-based radar observations obtained by the Goldstone Observatory. Later in 1990–2005 it was imaged in more detail by the Arecibo Observatory. The crater was initially known as the feature A. The bright appearance of rays in the radar images indicates that the crater is geologically young, because fresh and rough surfaces of young impact craters are good scatterers of radio waves.
Copland is an impact crater on Mercury. Its floor is flooded with volcanic smooth plains material, which could be related to the activity that formed the nearby bright vent known as Nathair Facula.
Matabei is an impact crater on Mercury. It has a set of dark rays. Dark rays are rare on Mercury, but other occurrences have been identified, such as at Mozart crater. Mozart crater is interpreted to have excavated dark material from depth during the impact event, creating dark streamers. The dark rays from Matabei may have a similar origin.
Ailey is a crater on Mercury. It has a diameter of 21 kilometers. Its name was adopted by the International Astronomical Union (IAU) in on April 24, 2012. Ailey is named for the American dancer and choreographer Alvin Ailey, who lived from 1931 to 1989.
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.
