Eponym | Elisabetta Pierazzo |
Pierazzo is a small lunar impact crater on the far side of the Moon. It is located within the north-northwestern section of the immense skirt of ejecta that surrounds the Mare Orientale impact basin. To the south is the Montes Cordillera mountain ring. To the west is the crater Lents.
This crater produced a broad, wispy ray system that extends for more than 100 km in all directions. The ejecta blanket contains multiple lobate impact melt flows, that extend to over 40 km from the centre of the 9.3 km diameter crater, and that appear dark in contrast to the surrounding material. [2]
The crater was named by the IAU in 2015, after Italian planetary scientist Elisabetta Pierazzo. [1] Pierazzo was herself a specialist in impact cratering and the associated production of impact melt. [2]
Linné is a small lunar impact crater located in the western Mare Serenitatis. It was named after Swedish botanist Carl von Linné. The mare around this feature is virtually devoid of other features of interest. The nearest named crater is Banting to the east-southeast. The estimated age of this copernican crater is only a few tens of millions of years. It was earlier believed to have a bowl shape, but data from the LRO showed that it has a shape of a flattened, inverted cone. The crater is surrounded by a blanket of ejecta formed during the original impact. This ejecta has a relatively high albedo, making the feature appear bright.
Lohse is a lunar impact crater on the eastern edge of Mare Fecunditatis. It is attached to the north rim of the larger crater Vendelinus. To the north is the prominent Langrenus. The interior of Lohse is rough, being partially covered by ejecta from Langrenus. It has a small central peak. An older impact is attached to the north rim, designated Langrenus E.
Artamonov is a lunar impact crater that is located on the far side of the Moon. The eroded outer rim of Artamonov does not have the circular shape of most lunar craters, and instead has the overall shape of three or four merged craters. The largest of these formations is in the south, with smaller circular bulges to the north and east.
Ashbrook is a large lunar impact crater that is located in the vicinity of the south pole on the far side of the Moon, and so cannot be viewed directly from the Earth. The eastern face of the crater has been overlain by the similar-sized Drygalski, and more than half the interior floor of Ashbrook is covered by the outer ramparts and ejecta of Drygalski. To the northwest is the walled plain Zeeman.
Atwood is a small lunar impact crater that is located on the Mare Fecunditatis, to the northwest of the prominent crater Langrenus. It forms a triple-crater formation with Naonobu attached to the north rim and Bilharz near the west rim.
King is a prominent lunar impact crater that is located on the far side of the Moon, and can not be viewed directly from Earth. The crater was named after Arthur Scott King and Edward Skinner King in 1970. Prior to that, this crater was known as Crater 211. It forms a pair with Ibn Firnas, which is only slightly larger and is attached to the northeast rim of King. To the northwest is the crater Lobachevskiy, and Guyot is located an equal distance to the north-northwest.
Biela is a lunar impact crater that is located in the rugged highlands of the southeastern Moon. It is named after Austrian astronomer Wilhelm von Biela. The crater lies to the east of Rosenberger, to the southeast of the Watt–Steinheil double crater.
Brashear is a lunar impact crater on the far side of the Moon, in the southern hemisphere in the vicinity of the south pole. The crater is named after the American astronomer John A. Brashear. It lies just to the south of the walled plain Antoniadi, within the larger crater's outer rampart of ejecta. To the northeast besides Antoniadi is the crater Numerov, and southeast lies the younger De Forest.
Drude is a lunar impact crater that lies on the far side of the Moon, in the rugged Montes Cordillera range that forms the outer ring around the Mare Orientale impact basin. It is located just behind the west-southwest limb, and this area is sometimes brought into sight from Earth during favorable librations. However, even at such times, the crater is viewed from the edge and little detail can be seen.
Chant is a lunar impact crater that is located on the far side of the Moon, behind the southwest limb as seen from the Earth. It lies within the southwestern part of the blanket of ejecta surrounding the Mare Orientale, beyond the Montes Cordillera mountain ring. To the west-northwest is the large walled plain Blackett. Southward is the crater Mendel.
Bondarenko is a lunar impact crater on the far side of the Moon. It is located to the northeast of the large, dark-floored crater Tsiolkovskiy, and south of the crater Chauvenet. This is a worn crater formation with an irregular floor, similar to other craters in the area, which are covered by ejecta from Tsiolkovskiy.
Chadwick is a lunar impact crater that lies on the far side of the Moon's surface, just beyond the southwestern limb. It is located to the northwest of the crater De Roy, and was previously designated De Roy X before being given its current name by the IAU. This region of the lunar surface lies at the southern end of the ejecta blanket that surrounds the Mare Orientale impact basin.
Dugan is a lunar impact crater that is located on the northern part of the Moon's far side. It lies to the southwest of the large walled plain Schwarzschild, and due north of the crater Compton.
Ellerman is a lunar impact crater on the far side of the Moon. It lies within the outer blanket of ejecta that surrounds the Mare Orientale impact basin, and is located to the west of the Montes Cordillera mountain range. To the northwest of Ellerman is the larger crater Gerasimovich.
Evdokimov is a lunar impact crater on the far side of the Moon. It lies to the east of the crater Evershed, and west-southwest of Gadomski. This is a worn and eroded feature with a somewhat indistinct outer rim that is little more than a slight ridge in the surface. The rim is better formed along the western and eastern sides. A small crater with a relatively high albedo lies along the inner wall to the northeast, and is surrounded by a small, bright skirt of ejecta. The interior floor is nearly featureless, with only a few indistinct small crater rims marking the surface.
Fényi is a small lunar crater on the far side of the Moon. It lies near the southern edge of the huge, braided skirt of ejecta that surrounds the Orientale impact Basin to the north. Less than two crater diameters to the southwest is the much larger crater Mendel.
Fridman is the remains of a lunar impact crater on the far side of the Moon. It lies due south of the huge walled plain Hertzsprung, and is attached to the northeastern rim of the crater Ioffe.
Patsaev is a lunar impact crater that lies on the far side of the Moon, to the northeast of the prominent crater Tsiolkovskiy. To the northwest is the smaller crater Lander.
Lents is a small lunar impact crater on the far side of the Moon. It is located within the north-northwestern section of the immense skirt of ejecta that surrounds the Mare Orientale impact basin. To the south is the Montes Cordillera mountain ring, and to the north-northeast is the damaged crater Elvey.
Meshcherskiy is an impact crater that is located on the Moon's far side, to the east-northeast of the larger Ostwald. To the east-southeast of Meshchersky is the crater Vetchinkin.
