Wilson (crater)
Wilson is a lunar impact crater that lies in the southern part of the Moon's near side, to the southwest of the large walled plain Clavius Christopher Clavius, (25 March 1538 – 6 February 1612) was a Jesuit German mathematician, head of mathematicians at the , and astronomer who was a member of the Vatican commission that accepted the proposed calendar invented by Aloysius .... It is nearly attached to the southeastern rim of the slightly larger crater Kircher. Almost due east lies Klaproth, another walled plain. This crater has a heavily eroded outer rim that now forms an irregular rise about the relatively level interior floor. The flooded remains of a crater intrudes part way into the rim and inner wall along the south-southeastern section. Several other small craters lie along the eastern and northern rim. The narrow section of surface between Wilson and Kircher is irregular and contains a small, cup-shaped crater that joins both outer rims. The interior floor ...

Kircher (crater)
Kircher is a lunar impact crater that is located in the south-southwestern part of the Moon, near the southern limb. In this position the crater appears foreshortened when viewed from the Earth Earth is the third planet from the Sun and the only astronomical object known to Planetary habitability, harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all .... It is less than one crater diameter due south of the crater Bettinus, and is nearly attached to Wilson along the south-southeast rim of Kircher. This crater is distinctive for an interior floor that is level and nearly featureless. It is marked by only a few tiny craterlets, with a single small craterlet near the north-northeast inner wall. The rim and inner wall has been worn and rounded by impacts, although only a few tiny craters lie across the rim. Attached to the outside of the western rim is a crater pair, with the larger of the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

Klaproth (crater)
Klaproth is an old Lunar craters, lunar impact crater that lies in the rugged southern highlands of the Moon's near side. Due to its location, this crater appears significantly foreshortened when viewed from the Earth. The southern rim of the crater is overlain by the similar-sized crater Casatus (crater), Casatus, and to the north-northeast lies Blancanus (crater), Blancanus. The outer rim of Klaproth has been deeply eroded, incised, and reshaped by a long history of bombardment. The rim to the north and east remains relatively circular, but the original rim along the western face has been overlain by satellite craters Klaproth G and Klaproth H, and other impacts. To the south the crater Casatus significantly intrudes into the interior floor. The remaining floor has been resurfaced by some material in the past, possibly fluidized ejecta or lava, leaving a level and nearly featureless surface that is marked only by a multitude of tiny craterlets. If this walled-plain once possesse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clavius (crater)
Clavius is one of the largest crater formations on the Moon and the second largest crater on the visible near side (very close in size to Deslandres). It is located in the rugged southern highlands of the Moon, to the south of the prominent ray crater Tycho. It is named for the Jesuit priest Christopher Clavius. Clavius is one of the largest craters of Nectarian age. Description Clavius' location toward the southern limb of the Moon causes it to appear oblong due to foreshortening. Its great size makes it visible to the unaided eye as a prominent notch in the terminator about one to two days after the Moon reaches first quarter. It has a low outer wall in comparison to its size and is heavily worn and pock-marked by craterlets. The rim does not significantly overlook the surrounding terrain making it a "walled depression". The inner surface of the rim is hilly, notched and varies in width with the steepest portion to the south. The rim has been observed to have a some ...

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter program, Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for Project Apollo, Apollo mapping and site selection. It was given a more general objective, to "perform a broad systematic photographic survey of lunar surface features in order to increase the scientific knowledge of their nature, origin, and processes, and to serve as a basis for selecting sites for more detailed scientific study by subsequent orbital and landing missions". It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission summary The spacecraft was placed in a Free-return trajectory, cislunar trajectory and injected into an elliptical near polar high lunar orbit for data acquisition. The orbit was with an inclination of 85.5 degrees and a period of 12 hours. After initial photography on May 11, 1967 problems started ...

Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, 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. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, 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 (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids.
