Venus
Venus is the second planet from the Sun. It is sometimes called Earth's "sister" or "twin" planet as it is almost as large and has a similar composition. As an interior planet to Earth, Venus (like Mercury) appears in Earth's sky never far from the Sun, either as morning star or evening star. Aside from the Sun and Moon, Venus is the brightest natural object in Earth's sky, capable of casting visible shadows on Earth at dark conditions and being visible to the naked eye in broad daylight. Venus is the second largest terrestrial object of the Solar System. It has a surface gravity slightly lower than on Earth and has a very weak induced magnetosphere. The atmosphere of Venus, mainly consists of carbon dioxide, and is the densest and hottest of the four terrestrial planets at the surface. With an atmospheric pressure at the planet's surface of about 92 times the sea level pressure of Earth and a mean temperature of , the carbon dioxide gas at Venus's surface is in t ...

Lada Terra
Lada Terra is a major landmass near the south pole of Venus which is centered at 60°S and 20°E and has a diameter of . It is defined by the International Astronomical Union as one of the three "major landmasses," or terrae, of Venus. The term "landmass" is not analogous to the landmass on Earth, as there are no apparent oceans on Venus. The term here applies to a substantial portion of land that lies above the average planetary radius, and corresponds to highlands. The broad region of Lada Terra contains massive coronae, rift zones, and volcanic plains as well as many other features that scientists use to attempt to piece together the history of this complex planet. The distinctive cross-cutting relationships found in the bedding of Lada Terra have been important in realizing relative ages of the extensional belts and coronae, as well as the complex tesserae features present planet-wide. In 1990 the Venus Radar Mapper revealed the largest outflow channel system on the planet loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Quadrangles On Mars
The surface of Mars has been divided into thirty cartographic quadrangles by the United States Geological Survey. Each quadrangle is a region covering a specified range of latitudes and longitudes on the Martian surface. The quadrangles are named after classical albedo features, and they are numbered from one to thirty with the prefix "MC" (for "Mars Chart"), with the numbering running from north to south and from west to east. The quadrangles appear as rectangles on maps based on a cylindrical map projection, but their actual shapes on the curved surface of Mars are more complicated Saccheri quadrilaterals. The sixteen equatorial quadrangles are the smallest, with surface areas of each, while the twelve mid-latitude quadrangles each cover . The two polar quadrangles are the largest, with surface areas of each. History In 1972, NASA's Mariner 9 mission returned thousands of photographs collectively covering more than 80% of the Martian surface. That year and the next, NASA' ...

List Of Quadrangles On The Moon
The Moon has been divided into 30 quadrangles by the United States Geological Survey at the 1:2,500,000 map scale. At the 1:1,000,000 scale it's divided into 144 quadrangles. The quadrangles are numbered in bands from north to south. Each band is then divided into a latitude-dependent number of quadrangles. At the poles, the bands consist of a single quadrangle, so LQ01 is a circle around the north pole. At the 1:1,000,000 scale, there are 12 latitude bands, 6 in each hemisphere. The bands nearest the equator are 16° high, and the first and last bands are 10° radius circles around the poles. The bands are then divided into quadrangles, but unlike the 1:2,500,000 system, the seam is placed at +10° longitude (so 0° longitude is in the middle of a quadrangle), and the numbering within a band starts between −80° and −90°: * (±90° to ±80°) 1 quadrangle of 360°, beginning at −80° * (±80° to ±64°) 8 quadrangles of 45°, beginning at −80° * (±64° to ± ...

List Of Quadrangles On Mercury
The surface of the planet Mercury has been divided into fifteen quadrangles, designated H-1 to H-15 (the 'H' stands for Hermes, the Greek equivalent of Mercury). The quadrangles are named for prominent surface features visible within each area. The quadrangles were initially named for albedo features, as these were the most prominent features visible before mapping was carried out by spacecraft. The mapping carried out with the images obtained by the ''Mariner 10'' flybys in 1974 and 1975 led to nine of the quadrangles being renamed for newly mapped prominent features. The remaining six quadrangles were completely unmapped by ''Mariner 10'' and were still referred to by their albedo feature names. Following the arrival of ''MESSENGER ''MESSENGER'' was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. The name is a backronym for "Mercury Surface, Space Environment, Geoche . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoebe Regio
Phoebe Regio is a regio on the planet Venus. It lies to the southeast of Asteria Regio. It is in diameter and is the principal feature of the V41 quadrangle, to which it gave its name. Four Soviet landers, Venera 11, Venera 12, Venera 13 and Venera 14 Venera 14 (russian: Венера-14 meaning Venus 14) was a probe in the Soviet Venera program for the exploration of Venus. Venera 14 was identical to the Venera 13 spacecraft, built to take advantage of the 1981 Venus launch opportunity. Ven ..., landed on the eastern side of Phoebe Regio and performed various scientific measurements. References Surface features of Venus {{crater-stub ...

Alpha Regio
Alpha (uppercase , lowercase ; grc, ἄλφα, ''álpha'', or ell, άλφα, álfa) is the first letter of the Greek alphabet. In the system of Greek numerals, it has a value of one. Alpha is derived from the Phoenician letter aleph , which is the West Semitic word for " ox". Letters that arose from alpha include the Latin letter A and the Cyrillic letter А. Uses Greek In Ancient Greek, alpha was pronounced and could be either phonemically long ( ː or short ( . Where there is ambiguity, long and short alpha are sometimes written with a macron and breve today: Ᾱᾱ, Ᾰᾰ. * ὥρα = ὥρᾱ ''hōrā'' "a time" * γλῶσσα = γλῶσσᾰ ''glôssa'' "tongue" In Modern Greek, vowel length has been lost, and all instances of alpha simply represent the open front unrounded vowel . In the polytonic orthography of Greek, alpha, like other vowel letters, can occur with several diacritic marks: any of three accent symbols (), and either of two breathing marks ...

Beta Regio
Beta Regio is a region of the planet Venus known as a ''volcanic rise''. Measuring about in extent, it constitutes a prominent upland region of Venus centered at . The first features that showed up in early radar surveys of the planet were given the names of letters of the Greek alphabet. Beta Regio was one of those features. It was discovered and named by Dick Goldstein in 1964. The name was approved by the International Astronomical Union's Working Group for Planetary System Nomenclature (IAU/WGPSN) between 1976 and 1979. Maxwell Montes, Alpha Regio, and Beta Regio are the three exceptions to the rule that the surface features of Venus are to be named for women or goddesses. Volcanic rises are broad, sloping highlands over across. They are cut by deep troughs across. These troughs are an example of continental rifting, and are evidence of surface tectonism. Beta Regio is cut by a radar-bright north-south trough called Devana Chasma Devana Chasma is a weak extensional rift ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aphrodite Terra
Aphrodite Terra is one of the three continental regions on the planet Venus, the others being Ishtar Terra and Lada Terra. It is named for Aphrodite, the Greek equivalent of the goddess Venus, and is found near the equator of the planet. Aphrodite Terra is about half the size of Africa, making it the largest of the terrae. Description Aphrodite Terra was named by the International Astronomical Union, the governing body for planetary and satellite nomenclature, after Aphrodite, the goddess of love. The name was chosen because Aphrodite is the Greek equivalent of the Roman goddess Venus. Located near the equator of Venus, Aphrodite Terra has an area about half the size of Africa, and is much smaller than the rougher Ishtar Terra. It is covered with deep rift valleys. Like Ishtar Terra, Aphrodite Terra also has mountain ranges but they are only about half the size of the mountains on Ishtar. Extending nearly two thirds around the planet, Aphrodite Terra's topography appe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadrangle (geography)
A "quadrangle" is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand "quad" is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad". From approximately 1947-1992, the USGS produced the 7.5 minute series, with each map covering an area one-quarter of the older 15-minute quad series, which it replaced. A 7.5 minute quadrangle map covers an area of . Both map series were produced via photogrammetric analysis of aerial photography using stereoplotters supplemented by field surveys. These maps employ the 1927 North American Datum (NAD27); conversion or a change in settings is necessary when using a GPS which by default employ the WGS84 geodetic datum. Beginning in 2009, the USGS made available digital versions of 7.5 minute quadrangle maps based on GIS data that use the NAD83 datum, which is typically within one met ...

Lavinia Planitia
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.
