Mistral is a crater on Mercury. [1] Its name was adopted by the International Astronomical Union (IAU) in 1976. Mistral is named for the Chilean poet Gabriela Mistral, who lived from 1889 to 1957. [2]
A large irregular depression and several smaller ones are present in the southeastern part of the crater floor. A similar depression is present in the crater Veronese which overlies the northwest rim of Mistral, and small ones are present in the unnamed crater to the southwest. The depressions are similar to those within Navoi, Lermontov, Scarlatti, and Praxiteles. The depressions resemble those associated with volcanic explosions. [3]
Aratus is a small lunar impact crater located on the highland to the south and east of the rugged Montes Apenninus range. It is a circular, cup-shaped crater with a relatively high albedo. It was named after Greek astronomer Aratus of Soli. To the east is the Mare Serenitatis, and to the southwest is the somewhat larger crater Conon. North-northeast of Aratus is the landing site of the Apollo 15 mission, just beyond Mons Hadley Delta.
Bragg is an ancient lunar impact crater that is located on the far side of the Moon, just beyond the northwest limb. This formation has been heavily eroded and reshaped by subsequent impacts, leaving an irregular depression in the surface. The most intact portion of the rim is along the western face, while the northern and eastern rim has been nearly worn away and is overlaid by several smaller craters. The most notable of these is Bragg H, which lies across the east-southeastern rim.
Ina is a peculiar small depression on the Moon, in Lacus Felicitatis. It is D-shaped, 2.9 km × 1.9 km wide and 64 m deep.
Julienne is a small, irregular depression that is located in Palus Putredinis, in the terrain to the southeast of the prominent crater Archimedes, and about 12 km west of the landing site of Apollo 15 at Hadley Rille.
The geology of Mercury is the scientific study of the surface, crust, and interior of the planet Mercury. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology. In planetary science, the term geology is used in its broadest sense to mean the study of the solid parts of planets and moons. The term incorporates aspects of geophysics, geochemistry, mineralogy, geodesy, and cartography.
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.
Raphael is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1976, and is named for the Italian painter Raphael.
Praxiteles is a crater on Mercury. It is one of 110 peak ring basins on Mercury.
Navoi is a crater on Mercury. It contains uncommon reddish material that indicates a different rock composition from its surroundings. Navoi also appears to have an irregularly shaped depression in its center. Such depressions have been seen elsewhere on Mercury, including within Praxiteles crater, and may indicate past volcanic activity.
Hesperia Planum is a broad lava plain in the southern highlands of the planet Mars. The plain is notable for its moderate number of impact craters and abundant wrinkle ridges. It is also the location of the ancient volcano Tyrrhena Mons. The Hesperian time period on Mars is named after Hesperia Planum.
Geddes is a crater on Mercury. It has a diameter of 84 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 2010. Geddes is named for the Irish stained glass artist Wilhelmina Geddes, who lived from 1887 to 1955.
Hitomaro is a crater on Mercury. It has a diameter of 105 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Hitomaro is named for the Japanese poet Kakinomoto no Hitomaro, who lived from the 650s to roughly 709.
Kipling is a crater on Mercury. It has a diameter of 164 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 2010. Kipling is named for the British author Rudyard Kipling, who lived from 1865 to 1936.
Mussorgskij is a crater on Mercury. It has a diameter of 125 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1979. Mussorgskij is named for the Russian composer Modest Mussorgsky, who lived from 1839 to 1881.
Enheduanna is a crater on Mercury. It has a diameter of 105 kilometers. Its name was suggested by Gagan Toor from India in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015. Enheduanna is named for the Sumerian poet Enheduanna. The craters Carolan, Kulthum, Karsh, and Rivera were also named as part of the contest.
Namatjira is a crater on Mercury. It has a diameter of 34 kilometers. Its name was adopted by the International Astronomical Union (IAU) on September 25, 2015. Namatjira is named for the Australian aboriginal artist Albert Namatjira.
Rilke is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1976. Rilke is named for the German poet Rainer Maria Rilke.
Donelaitis is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) on May 15, 2013. Donelaitis is named for the Lithuanian poet Kristijonas Donelaitis.
Veronese is a crater on Mercury. It has a diameter of 45 kilometres. Its name was adopted by the International Astronomical Union (IAU) on June 28, 2021. Veronese is named for the Italian painter Paolo Veronese.
Vazov is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 2020. The crater is named for Bulgarian poet Ivan Vazov.
