Mons Penck
Mons Penck is a mountain promontory on the near side of the Moon. It lies just to the northeast of the crater Kant, to the north of Ibn-Rushd and the Rupes Altai scarp. Southeast of Mons Penck are the prominent craters Theophilus and Cyrillus. The selenographic coordinates of this peak are 10.0° S, 21.6° E. It has a diameter of about 30 km at the base and climbs to an altitude of over 4 km (13,000 feet). It was named after Albrecht Penck (1858–1945), a German geographer and geologist A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them.

Apollo 16
Apollo 16 (April 1627, 1972) was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. It was the second of Apollo's " J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved to not be the case. The mission was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. Launched from the Kennedy Space Center in Florida on April 16, 1972, Apollo 16 experienced a number of minor glitches en route to the Moon. These culminated with a problem with the spaceship's main engine that resulted in a six-hour delay in the Moon landing as NASA managers contemplated having the astronauts abort the mission and return to E ...

List Of Mountains On The Moon
Mountains on the Moon have heights defined relative to various vertical datums. In the 1960s, the U.S. Army Mapping Service used elevation relative to 1,737,988 meters from the center of the Moon. In the 1970s, the U.S. Defense Mapping Agency used 1,730,000 meters. The '' Clementine'' topographic data published in the 1990s uses 1,737,400 meters. This table is not comprehensive, and does not list the highest places on the Moon. ''Clementine'' data show a range of about 18,100 meters from lowest to highest point on the Moon. The highest point, located on the far side of the Moon, is approximately 6,500 meters higher than Mons Huygens (usually listed as the tallest mountain).

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] |
Albrecht Penck
Albrecht Penck (25 September 1858 – 7 March 1945) was a German geographer and geologist and the father of Walther Penck. Biography Born in Reudnitz near Leipzig, Penck became a university professor in Vienna, Austria, from 1885 to 1906, and in Berlin from 1906 to 1927. There he was also the director of the Institute and Museum for Oceanography by 1918. He dedicated himself to geomorphology and climatology, and he raised the international profile of the Vienna school of physical geography. With Eduard Brückner, he coauthored ''Die Alpen im Eiszeitalter'', a work in which the two scientists identified the four ice ages of the European Pleistocene ( Gunz, Mindel, Riss, Würm); these being named after the river valleys that were the first indication of each glaciation. In 1886, he married the sister of the successful Bavarian regional writer Ludwig Ganghofer. In 1945, Penck died in Prague. In Vienna, he taught the Polish geographer Eugeniusz Romer and Ukrainian geographe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Kant (crater)
Kant is a small lunar impact crater that is located to the northwest of the prominent crater Cyrillus and the comparably sized Ibn Rushd. To the northwest is Zöllner, and to the east is Mons Penck. This last feature forms a mountainous promontory reaching a height of about 4 km. The crater is named after the German philosopher Immanuel Kant. This crater has a well-defined and somewhat uneven rim that is roughly circular in shape. The inner walls have a higher albedo Albedo (; ) is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that refl ... than the surrounding surface, giving them a lighter appearance.

Ibn-Rushd (crater)
Ibn-Rushd is a lunar impact crater located to the northwest of the larger crater Cyrillus. To the northwest is the crater Kant and to the north is Mons Penck, a mountain promontory. The crater is somewhat eroded with age, and the southern rim is overlain by a pair of smaller craters named Cyrillus B and C. The crater floor is relatively flat, and lacks a central peak. In 1976 the crater was named after Ibn Rushd (Latinized as Averroes), the 12th-century Muslim polymath from the Islamic Spain Al-Andalus translit. ; an, al-Andalus; ast, al-Ándalus; eu, al-Andalus; ber, ⴰⵏⴷⴰⵍⵓⵙ, label= Berber, translit=Andalus; ca, al-Àndalus; gl, al-Andalus; oc, Al Andalús; pt, al-Ândalus; es, al-Ándalus () was the Mu ..., whose many scientific accomplishments included analysis of the lunar surface.

Rupes Altai
Rupes Altai is an escarpment in the lunar surface that is located in the southeastern quadrant of the Moon's near side. It is named for the Altai Mountains in Asia, and is the most prominent lunar escarpment. The selenographic coordinates of this feature are , and it has a length of about 427 km. The southeastern end of the cliff terminates along the western edge of the crater Piccolomini. It then arcs irregularly towards the north, climbing to heights of nearly a kilometer. The northern end of the arc is an irregular region with no clearly defined terminus, where it brackets the prominent craters Theophilus, Cyrillus, and Catharina. This cliff forms the southwestern rim of the Nectaris impact basin. This feature is difficult to locate during the full moon when the sunlight is nearly overhead. It appears as a bright, winding line about five days after the new moon, and casts a long, irregular shadow about four days after the full moon, when the sunset terminator is nearby and ...

Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. The terms ''scarp'' and ''scarp face'' are often used interchangeably with ''escarpment''. Some sources differentiate the two terms, with ''escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theophilus (crater)
Theophilus is a prominent lunar impact crater that lies between Sinus Asperitatis in the north and Mare Nectaris to the southeast. It partially intrudes into the comparably sized crater Cyrillus to the southwest. To the east is the smaller crater Mädler and further to the south-southeast is Beaumont. It was named after the 4th-century Coptic Pope Theophilus I of Alexandria.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. Theophilus, Cyrillus and Catharina form a prominent group of large craters visible on the terminator 5 days after the new moon. Description The rim of Theophilus has a wide, terraced inner surface that shows indications of landslips. It is 4200 metres deep with massive walls and has broken into a second formation, Cyrillus. It was created during the Eratosthenian period, from 3.2 to 1.1 billion years ago. It has an imposing central mountain, 1,400 metres high, with four summits. The floor of the crater is relatively flat, and it has a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyrillus (crater)
Cyrillus is a lunar impact crater located on the northwest edge of Mare Nectaris. Intruding into the northeast rim is the slightly larger, and younger crater Theophilus. To the south is another prominent crater named Catharina. Together these three craters form a prominent trio in the southeast quadrant of the Moon. To the northwest is Ibn-Rushd. Cyrillus is named after Saint Cyril of Alexandria, a 4th-century Coptic Pope and theologian. The floor of Cyrillus contains a reduced central hill and the considerable crater Cyrillus A. The walls of the broken formation of Cyrillus remain intact until the point of junction with Theophilus.Moore, Patrick (2001). ''On the Moon''. Sterling Publishing Co.. . p. 81, 209 Slightly northeast of its center, three rounded mountains rise to heights of 1,000 metres above Cyrillus' floor: Cyrillus Alpha, Delta, and Eta. A tiny crater with bright rays on the east side of Cyrillus has been named Shioli. Satellite craters By convention these featur ...

Selenographic Coordinates
The selenographic coordinate system is used to refer to locations on the surface of Earth's moon. Any position on the lunar surface can be referenced by specifying two numerical values, which are comparable to the latitude and longitude of Earth. The longitude gives the position east or west of the Moon's prime meridian, which is the line passing from the lunar north pole through the point on the lunar surface directly facing Earth to the lunar south pole. (See also Earth's prime meridian.) This can be thought of as the midpoint of the visible Moon as seen from the Earth. The latitude gives the position north or south of the lunar equator. Both of these coordinates are given in degrees. Astronomers defined the fundamental location in the selenographic coordinate system by the small, bowl-shaped satellite crater ' Mösting A'. The coordinates of this crater are defined as: : Later, the coordinate system has become more precisely defined due to the Lunar Laser Ranging E ...
