Eponym Sanai of Ghazna

Sanai is a large, ancient crater on Mercury. Its name was adopted by the International Astronomical Union in 2014, after the Persian poet, Sanai of Ghazna. [1]

The crater, or basin, has prominent radial troughs to the northeast (similar to Imbrium sculpture on the moon), and it is floor is covered with smooth plains. Prior to naming, it was identified as b38. [2] It is Tolstojan in age. [3]

Hitomaro crater is to the southwest of Sanai, and the crater Dvorák is on its northwest rim.

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.

Haystack Catena is a catena on Mercury. It superficially resembles a graben but is a chain of overlapping secondary craters. It is named after Haystack Observatory, and was originally named Haystack Vallis when it was imaged by Mariner 10 in 1974, but the name was changed in 2013 to better reflect its origin. It is approximately 274 km long. It is located near the center of the Kuiper quadrangle, and it is radial to a large, unnamed crater that is Tolstojan in age.

To Ngoc Van is a pit-floored crater on Mercury, named after the Vietnamese artist Tô Ngọc Vân. It was discovered in January 2008 during the first flyby of the planet by MESSENGER spacecraft. Its floor displays an irregularly shaped collapse feature, which is called a central pit. The size of the pit is 21 × 10 km. Such a feature may have resulted from collapse of a magma chamber underlying the central part of the crater. The collapse feature is an analog of Earth's volcanic calderas.

<span class="mw-page-title-main">Hokusai (crater)</span> Crater 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.

<span class="mw-page-title-main">Derain (crater)</span> Crater on Mercury

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.
