Asclepi (crater)
Asclepi is a heavily eroded lunar impact crater that lies in the rugged southern highlands of the 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 .... The outer rim has been worn down and rounded by many millions of years of subsequent impacts, so that it is now nearly level with the surrounding terrain. As a result, the crater is now little more than a depression in the surface. The interior is nearly flat and relatively featureless. The rim of Asclepi is marked only by a small crater across the western rim, and several tiny craterlets. The satellite crater Hommel K is a more recent impact that is attached to the southeast rim. This is a bowl-shaped formation with a sharp edge and a small central floor. Nearby craters of note include Pitiscus to the north-northeast, Hommel ...

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 occu ...

Lunar Craters
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. Scientific opinion as to the origin ... [...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] |
Pitiscus (crater)
Pitiscus is a lunar impact crater that lies in the southern part of the Moon's near side, just to the northwest of the larger crater Hommel. It was named after German mathematician Bartholomaeus Pitiscus in 1935. The crater is worn, but still forms a prominent feature upon the surface. The rim is roughly circular, but appears oval from the Earth due to foreshortening. There is an outward bulge to the south-southeast where the interior has slumped. The remainder of the inner wall still displays terraces, although they are worn and rounded due to erosion. The interior floor is level and appears to have been resurfaced by lava. There is a low central peak formation at the midpoint of the interior, and the northern end of this ridge is overlaid by the circular crater Pitiscus A. A slumped and somewhat irregular crater, Pitiscus E, lies along the inner wall to the west-southwest. The interior floor is also marked by several other tiny craters alongside the eastern interior wall. Piti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hommel (crater)
Hommel is a lunar impact crater located in the southeast section of the Moon, in a region that is deeply impacted with a multitude of impact craters. The most notable craters nearby are Pitiscus to the north; Rosenberger due east; and Nearch to the southeast. The prominent crater Vlacq is nearly attached to the northeast rim. Also nearby is Asclepi to the west. Hommel is about 120 kilometers in diameter and its walls reach heights of 2,800 meters. It is from the Pre-Nectarian period, 4.55 to 3.92 billion years ago.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. The eroded outer wall of Hommel is overlain and incised by a number of smaller but still sizeable craters. Hommel C overlays the western rim and Hommel A the north. Intruding into the rim are Hommel H to the northwest, Hommel B in the east, and Hommel P along the southern wall. These craters are in turn overlain by smaller craterlets. The crater Hommel D lies on the southern part of the inner floor, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baco (crater)
Baco is a lunar impact crater that lies in the rugged southern highlands on the near side of the Moon. The rim and inner wall has been eroded and worn by countless minor impacts since the original formation of the crater. As a result, any terraces have been worn smooth and the rim is overlaid by several tiny craterlets. The interior floor is nearly flat, with no characteristic central peak at the midpoint and no small craters of significance. There are several minor craters located in the surrounding terrain, including the satellite craters Baco A just to the south and Baco B to the northwest. Further to the north is the crater Breislak, and equally distant to the northeast is Ideler. Further to the west is Cuvier, while Asclepi lies to the southeast. Although this crater was named after the Englishman Roger Bacon, it was chosen by the German German(s) may refer to: * Germany (of or related to) ** Germania (historical use) * Germans, citizens of Germany, people of German an ...

Tannerus (crater)
Tannerus is a small lunar impact crater that is located in the rugged southern highlands of the Moon. It lies within a couple of crater diameters of Asclepi to the northeast, and some distance due east of Jacobi Jacobi may refer to: * People with the surname Jacobi (surname), Jacobi Mathematics: * Jacobi sum, a type of character sum * Jacobi method, a method for determining the solutions of a diagonally dominant system of linear equations * Jacobi eigenva .... The rim of this crater is very close to circular, with only a slight inward bulge along the north edge where it is joined to Tannerus P. The edge is sharp and well-defined, although there are tiny impacts along the rim in the west and south. The crater floor is level and free of markings or features of note. 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 Tannerus.
