Rupes
Rupes (plural ) is the Latin word for 'cliff'. It is used in planetary geology to refer to escarpments on other worlds. , the IAU has named 62 such features in the Solar System, on Mercury (17), Venus (7), the Moon (8), Mars (23), the asteroids Vesta (2) and Lutetia (2), and Uranus's satellites Miranda (2) and Titania (1). How rupes formed is, , a matter of speculation. Compressional strain from the cooling of the crust of terrestrial planets and large scale displacement due to impacts are the two dominant theories.

Rupes Tenuis
Rupes Tenuis ( la, thin cliff) is a Martian north polar scarp. It is named after one of the classical albedo features on Mars. Its name was officially approved by IAU in 1988. It extends from latitude 74.94°N to 82.2°N and from longitude 242.12°E to 300.77°E (59.23°W – 117.88°W). Its centre is located at latitude 81.6°N longitude 85.47°W. It marks the outer perimeter of Planum Boreum from longitude 242.12°E to 300.77°E, and it is formed by the eastern extension of the Olympia Cavi, a series of local troughs and depressions, which become longer and deeper as they merge to create the Rupes Tenuis scarp formation. The scarp is located to the west of Chasma Boreale, at the base of Planum Boreum, and its height varies from a few hundred metres to a maximum of approximately 1000 metres. Local topography Immediately to the south of Rupes Tenuis, approximately at 285ºE, lies Abalos Mensa, a convex formation of approximately 180 kilometer span, shaped like a wedge when vi ...

List Of Lunar Features
The surface of the Moon has many features, including mountains and valleys, craters, and ''maria''—wide flat areas that look like seas from a distance but are probably solidified molten rock. Some of these features are listed. Maria features ''Lunar maria'' (singular ''mare'') are large, dark, regions of the Moon. They do not contain any water, but are believed to have been formed from molten rock from the Moon's mantle coming out onto the surface of the Moon. This list also includes the one ''oceanus'' and the features known by the names ''lacus'', ''palus'' and ''sinus''. The modern system of lunar nomenclature was introduced in 1651 by Riccioli. Riccioli's map of the Moon was drawn by Francesco Maria Grimaldi, who has a crater named after him. ''Maria'' and ''Oceanus'' There is also a region on the Lunar farside that was briefly misidentified as a mare and named '' Mare Desiderii'' (Sea of Dreams). It is no longer recognized. Other former maria include: * Mare Parvum ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Geological Features On Venus
This is a list of geological features on Venus. Venus is the second planet from the Sun. Venus is classified as a terrestrial planet and it is sometimes called Earth's "sister planet" owing to their similar size, gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to Earth). The surface of Venus is covered by a dense atmosphere and presents clear evidence of former violent volcanic activity. It has shield and composite volcanoes similar to those found on Earth. Valles Cytherean valleys are called by the Latin term ''valles'', and are named after river goddesses or after words for the planet Venus (including terms for the ''morning star'' or ''evening star'' specifically) in various languages. Undae Undae on Venus refer to dune fields and are named after desert goddesses. Tesserae Tesserae are areas of polygonal terrain. They are named after goddesses in world mythologies. Rupes Scarps on Venus are called rupes and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rousillon Rupes
Rousillon Rupes is a scarp (''rupes'' is Latin for "cliff") on the surface of the Uranian moon Titania named after "Bertram, count of Rousillon" (an Elisabethan English misspelling for Roussillon) in William Shakespeare's comedy All's Well That Ends Well. The 402 km long feature is a normal fault situated near the equator and running perpendicular to it. The scarp cuts impact craters, which probably means that it was formed at a relatively late stage of moon's evolution, when the interior of Titania expanded and its ice crust cracked as a result. Rousillon Rupes has only few crater superimposed on it, which also implies its relatively young age. The scarp was first imaged by Voyager 2 ''Voyager 2'' is a space probe launched by NASA on August 20, 1977, to study the outer planets and interstellar space beyond the Sun's heliosphere. As a part of the Voyager program, it was launched 16 days before its twin, '' Voyager 1'', o ... spacecraft in January 1986. Reference ...

Verona Rupes
Verona Rupes is a cliff on Miranda, a moon of Uranus. It was discovered by the ''Voyager 2'' space probe in January 1986. The cliff face, previously thought to be from high, as of 2016 is estimated to be high, which makes it the tallest known cliff in the Solar System The Solar System Capitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar .... It may have been created by a major impact, which caused the moon to disrupt and reassemble, or by the crust rifting. Given Miranda's low gravity, it would take about 12 minutes to fall from the top, reaching the bottom at the speed of about 200 km/h.

Miranda (moon)
Miranda, also designated Uranus V, is the smallest and innermost of Uranus's five round satellites. It was discovered by Gerard Kuiper on 16 February 1948 at McDonald Observatory in Texas, and named after Miranda from William Shakespeare's play '' The Tempest''. Like the other large moons of Uranus, Miranda orbits close to its planet's equatorial plane. Because Uranus orbits the Sun on its side, Miranda's orbit is perpendicular to the ecliptic and shares Uranus' extreme seasonal cycle. At just 470 km in diameter, Miranda is one of the smallest closely observed objects in the Solar System that might be in hydrostatic equilibrium (spherical under its own gravity). The only close-up images of Miranda are from the ''Voyager 2'' probe, which made observations of Miranda during its Uranus flyby in January 1986. During the flyby, Miranda's southern hemisphere pointed towards the Sun, so only that part was studied. Miranda probably formed from an accretion disc that surrou ...

Titania (moon)
Titania (), also designated Uranus III, is the largest of the moons of Uranus and the List of natural satellites by diameter, eighth largest moon in the Solar System at a diameter of . Discovered by William Herschel in 1787, it is named after the Titania (A Midsummer Night's Dream), queen of the fairies in Shakespeare's ''A Midsummer Night's Dream''. Its orbit lies inside Uranus's magnetosphere. Titania consists of approximately equal amounts of ice and rock (geology), rock, and is probably differentiated into a rocky core (geology), core and an icy mantle (geology), mantle. A layer of liquid water may be present at the core–mantle boundary. Its surface, which is relatively dark and slightly red in color, appears to have been shaped by both impacts and endogenic processes. It is covered with numerous impact craters reaching up to in diameter, but is less heavily cratered than Oberon (moon), Oberon, outermost of the five large moons of Uranus. It may have undergone an early end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury (planet)
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god ' ( Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its synodic period of approximately 116 days. The synodic proximity of Mercury to Earth makes Mercury mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planetary Geology
Planetary geology, alternatively known as astrogeology or exogeology, is a planetary science discipline concerned with the geology of the celestial bodies such as the planets and their moons, asteroids, comets, and meteorites. Although the geo- prefix typically indicates topics of or relating to Earth, planetary geology is named as such for historical and convenience reasons; due to the types of investigations involved, it is closely linked with Earth-based geology. These investigations are centered around the composition, structure, processes, and history of a planet. Planetary geology includes such topics as determining the properties and processes of the internal structure of the terrestrial planets, and also looks at planetary volcanism and surface processes such as impact craters, fluvial and aeolian processes. The structures and compositions of the giant planets and their moons are also examined, as is the make-up of the minor bodies of the Solar System, such as aster ...
