Tseraskiy (crater)
Tseraskiy (Ceraski) is an impact crater on the Moon's Far side (Moon), far side, approximately in diameter. It is located to the north-northeast of the huge walled plain Planck (crater), Planck, and to the southeast of the crater Pauli (crater), Pauli. To the east-northeast of Tseraskiy is Crocco (crater), Crocco. This is an eroded crater formation and the outer rim has been steady worn down to a roughly circular ridge with rounded edges. This crater overlies an older crater along the southwest side. There is a small crater along the exterior of the rim to the northeast. The interior floor is relatively level and is marked by several small and tiny craterlets, particularly in the western half. In some publications name has been spelt as Ceraski. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Tseraskiy.

Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. The first images f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitol'd Karlovic Tseraskiy
Vitold Karlovich Tserasky also spelled Witold Cerasky (Russian:Витольд Карлович Цераский; 9 May 1849 – 29 May 1925) was a Russian astronomer and inventor of astronomical tools and techniques. The asteroid 807 Ceraskia and the Lunar crater Tseraskiy are named after him. Tserasky was born in Slutsk, Minsk where his father of Polish–Lithuanian descent was a geography teacher. A visit of Donati's comet in 1858 sparked an interest in Tserasky and he joined Moscow University in 1867 where he spent time at the astronomical observatory . He joined the astronomical observatory as an assistant and made a trip in 1874 to Kyakhta to make observations on the transit of Venus frameless, upright=0.5 A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a trans .... He then took an interest in astro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Far Side (Moon)
The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the near side, because of synchronous rotation in the Moon's orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury and Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere is sometimes called the "dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each side of the Moon experiences two weeks of sunlight while the opposite side experiences two weeks of night. About 18 percent of the far side is occasionally visible from Earth due to libration. The remaining 82 percent remained unobserved until 1959, when it was photographed by the Soviet Luna 3 space probe. The Soviet Academy of Sciences published the ...

Planck (crater)
Planck is a large lunar impact crater, approximately 319 kilometers in diameter, that is located in the southern hemisphere of the Moon, on the far side as seen from the Earth. It lies to the west of the walled plain Poincaré, another enormous formation only slightly larger than Planck. Lying across the southeast rim of Planck is the crater Prandtl, to the northeast is Hildegard, and to the west is Fechner. Planck is located within the South Pole–Aitken basin. Formation According to a 2012 study, Planck formed roughly 4.09 Ga (billion years) ago, partially resurfacing the area of the South Pole-Aitken basin that it impacted. Description Like many lunar formations of this size, the outer rim has been damaged and eroded by lesser impacts, leaving a rugged ring of peaks and ridges that is notched and incised by small craters. The western rim of this walled plain is neatly overlain by a long lunar valley designated the Vallis Planck. Despite its name, however, this valley ...

Pauli (crater)
Pauli is a lunar impact crater that is located on the Moon's far side. It lies about halfway between the lunar equator and southern pole, across the southern rim of the larger walled plain Roche. This crater has a well-defined outer rim that is only mildly worn by impact erosion. A small crater lies on the inner side along the south, and another on the opposite face of the crater to the north. There is some slight terracing along the southeast inner wall, but the remainder displays more of a radially grooved appearance. The inner wall is narrower along the northern side where it overlies Roche. The interior floor has been flooded with lava, leaving a low-albedo surface that is darker than the surrounding terrain. In this respect it is similar to the crater Jules Verne located about four crater diameters to the northeast. There is a low ridge structure near the midpoint, and the remains of a ghost crater A palimpsest , in planetary astronomy, is an ancient crater that has ...

Crocco (crater)
Crocco is a lunar impact crater that is located on the far side of the Moon from the Earth. It is located to the northeast of the huge walled plain Planck, and northwest of the equally huge Poincaré. Just to the north, within one crater diameter, is the crater Koch. This is a nearly circular crater formation whose eastern rim has been partly overlain by the satellite crater Crocco G. The rim has received some erosion, but it retains a well-defined edge. A small craterlet lies across the north-northeast rim. Just to the west-southwest of Crocco, nearly attached to the rim, is the satellite crater Crocco R. The northwestern half of the interior floor is level and almost featureless; displaying the appearance of having been resurfaced by lava Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
807 Ceraskia
807 Ceraskia ( ''prov. designation'': ''or'' ) is an elongated Eos asteroid from the outer regions of the asteroid belt. It was discovered on 18 April 1915, by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in southwest Germany. The S-type asteroid has a rotation period of 7.4 hours and measures approximately in diameter. It was named after Belarusian–Soviet astronomer Vitold Cerasky (1849–1925). Orbit and classification ''Ceraskia'' is a core member the Eos family (), the largest asteroid family of the outer main belt consisting of nearly 10,000 known asteroids. It orbits the Sun in the outer asteroid belt at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,913 days; semi-major axis of 3.02 AU).
