Arrakis Planitia
Arrakis Planitia is a planitia (plain) on Titan, the largest moon of the planet Saturn. It is located in Titan's southern hemisphere, between 74 and 80° south and 113–134° east, within the Mezzoramia region. Arrakis Planitia is named after Arrakis, a fictional desert planet A desert planet, also known as a dry planet, an arid planet, or a dune planet, is a theoretical type of terrestrial planet with a surface consistency similar to Earth's hot deserts.

Planitia
In geography, a plain is a flat expanse of land that generally does not change much in elevation, and is primarily treeless. Plains occur as lowlands along valleys or at the base of mountains, as coastal plains, and as plateaus or uplands. In a valley, a plain is enclosed on two sides, but in other cases a plain may be delineated by a complete or partial ring of hills, by mountains, or by cliffs. Where a geological region contains more than one plain, they may be connected by a pass (sometimes termed a gap). Coastal plains mostly rise from sea level until they run into elevated features such as mountains or plateaus. Plains are one of the major landforms on earth, where they are present on all continents, and cover more than one-third of the world's land area. Plains can be formed from flowing lava; from deposition of sediment by water, ice, or wind; or formed by erosion by the agents from hills and mountains. Biomes on plains include grassland (temperate or subtropical), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arrakis
Arrakis ()—informally known as Dune and later called Rakis—is a fictional desert planet featured in the Dune (franchise), ''Dune'' series of novels by Frank Herbert. Herbert's first novel in the series, 1965's ''Dune (novel), Dune'', is considered one of the greatest science fiction novels of all time,Touponce, William F. (1988), ''Frank Herbert'', Boston, Massachusetts, Boston, Massachusetts: Twayne Publishers imprint, G. K. Hall & Co, pg. 119, . "''Locus (magazine), Locus'' ran a poll of readers on April 15, 1975, in which ''Dune'' 'was voted the all-time-best science-fiction novel ... It has sold over ten million copies in numerous editions.'" and it is sometimes cited as the best-selling science fiction novel in history. In ''Dune'', the planet is the home of the Fremen (Zensunni wanderers), and subsequently is the Imperial Capital of the House Atreides, Atreides Empire. Arrakis is the third planet orbiting the star Canopus (star), Canopus, and it in turn is orbited b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Titan (moon)
Titan is the largest moon of Saturn and the second-largest natural satellite in the Solar System. It is the only moon known to have a dense atmosphere, and is the only known object in space other than Earth on which clear evidence of stable bodies of surface liquid has been found. Titan is one of the seven gravitationally rounded moons in orbit around Saturn, and the second most distant from Saturn of those seven. Frequently described as a planet-like moon, Titan is 50% larger (in diameter) than Earth's Moon and 80% more massive. It is the second-largest moon in the Solar System after Jupiter's moon Ganymede, and is larger than the planet Mercury, but only 40% as massive. Discovered in 1655 by the Dutch astronomer Christiaan Huygens, Titan was the first known moon of Saturn, and the sixth known planetary satellite (after Earth's moon and the four Galilean moons of Jupiter). Titan orbits Saturn at 20 Saturn radii. From Titan's surface, Saturn subtends an arc of 5.09 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn's interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but which has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's. The outer atmosphere is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Desert Planet
A desert planet, also known as a dry planet, an arid planet, or a dune planet, is a theoretical type of terrestrial planet with a surface consistency similar to Earth's hot desert A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one ...s. History A 2011 study suggested that not only are life-sustaining desert planets possible, but that they might be more common than Earth analog, Earth-like planets. The study found that, when modeled, desert planets had a much larger habitable zone than ocean planets. The same study also speculated that Venus may have once been a habitable desert planet as recently as 1 billion years ago. It is also predicted that Future of the Earth#Ocean-free era, Earth will become a desert planet within a billion years due to the Sun's increasing luminosity. A st ...

Frank Herbert
Franklin Patrick Herbert Jr. (October 8, 1920February 11, 1986) was an American science fiction author best known for the 1965 novel '' Dune'' and its five sequels. Though he became famous for his novels, he also wrote short stories and worked as a newspaper journalist, photographer, book reviewer, ecological consultant, and lecturer. The ''Dune'' saga, set in the distant future, and taking place over millennia, explores complex themes, such as the long-term survival of the human species, human evolution, planetary science and ecology, and the intersection of religion, politics, economics and power in a future where humanity has long since developed interstellar travel and settled many thousands of worlds. ''Dune'' is the best-selling science fiction novel of all time, and the entire series is considered to be among the classics of the genre. Biography Early life Frank Patrick Herbert Jr. was born on October 8, 1920, in Tacoma, Washington, to Frank Patrick Herbert Sr. and Ei ...

Dune (franchise)
''Dune'', also known as the ''Dune Chronicles'', is an American science fiction media franchise that originated with the 1965 novel '' Dune'' by Frank Herbert and has continued to add new publications. ''Dune'' is frequently described as the best selling science fiction novel in history. It won the inaugural Nebula Award for Best Novel and the Hugo Award in 1966, and was later adapted into a 1984 film, a 2000 television miniseries, and a 2021 film. The latter will be followed by a 2023 direct sequel. Herbert wrote five sequels, the first two of which were adapted as a miniseries called ''Frank Herbert's Children of Dune'' in 2003. ''Dune'' has also inspired some traditional games and a series of video games. Since 2009, the names of planets from the ''Dune'' novels have been adopted for the real-world nomenclature of plains and other features on Saturn's moon Titan. Frank Herbert died in 1986. Beginning in 1999, his son Brian Herbert and science fiction author Kevin J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
