Its important to remember that Herbert wrote the first Dune novel way back in 1965. and their sides.[1]. Wiki User 2015-02-03 19:28:20 Study now See answer (1) Copy Uranus does not have any suns. The book also mentions that polar ice caps exist, at least in the northern hemisphere, and have for a long time. Vassek was a small blue-and-green planet located in the Wazta sector's Vassek systemto which the planet gave its nameof the Outer Rim Territories, at grid square I-17 on the Standard Galactic Grid. Specifically, the kinds of life forms that existed on Arrakis included the following: Various animals were part of the ecosystem, including the following: Before the discovery of the spice melange on the planet, Arrakis was of little tactical, biological, or geological interest to the inhabitants of the Old Empire. The sun is actually a star, our nearest star, but there are lots of stars out there. Such temperatures are deadly for humans. The crust of Arrakis is rather thin, averaging only 10 kilometers in thickness. The climate is so brutally hot that anyone who ventures out into the Sun must wear a stillsuitwhich cools the body and recycles the body's moistureor face death. The greatest is This is important as stated in the book that there is no rainfall on Arrakis, no standing bodies of open water and little atmospheric moisture that can be reclaimed. Itis covered in massive dune seas with occasional rock canyons, escarpments, and salt pans. Earth's solar system has only one sun, but if the word "sun" is taken to mean "any star with planets in orbit," the Milky Way might have as many as 400 billion suns. [9][7], Considerable dust was present in the atmosphere at all times. Arrakis is the third planet of Canopus, a star much larger and hotter than our sun. Now that may sound big, but Sagittarius A* is small compared to other supermassive black holes. It is later transformed into a festival city known as Onn, explicitly for the worship of the Tyrant Leto II. The team says Arrakis is pretty realistic and habitable, for the most part. [12] The Citadel itself is taken apart in the Famine Times after the death of Leto II in search of his alleged hoard of spice. The chasms expand and contract rapidly and can be crossed only by very long and expensive bridges, which are quickly destroyed. Various birds and bats existed in the ecosystems of the planet. This is counter intuitive as the equatorial region receives more energy from the sun. The cooler and denser air from the poles flowed along the surface, and was warmed quickly by surface radiation. Between these polar regions, temperatures range from -2 to 138 degrees Fahrenheit (-19 to 59 degrees Celsius). One of the many reasons Dune continues to fascinate readers for over half a century. Explanation: Saturn orbits the same sun as Earth.Our solar system has only one sun and that sun is shared by all the planets in our solar system, including Saturn, and Earth which is where we are currently living :) Answer link. However, I definitely remember the first book mentioning that Arrakis's sky is NOT blue, at least not the "sky blue" of our . No known effect on Arrakis weather has been proven to be a result of this interaction. Dune home of the spice, greatest of treasure in the universe. "We might need to occasionally suspend disbelief, but much of Arrakis itself would indeed be habitable, albeit . Paul Muad'Dib continues the efforts to terraform Arrakis into a green world, a plan begun by the Fremen under the guidance of Imperial Planetologist Pardot Kynes and his son Liet-Kynes. In these Fremen Paul finds an incomparable fighting force who are already disgruntled by Imperial rule. The uncommon "polar sinks" were thus created, and the polar caps lie below bled-level. Some forms of flora existed on the planet, including the creosote bush. Water ice is present in the polar caps, as is the The process started very slowly due to political and other reasons, before massive plantings began. Nights were generally and relatively cool. Since the resulting ice caps exist in depressions it has been suggested that energy from Canopus be focused with large solar satellite arrays to form polar lakes. Arrakis evolved after formation much as other planets of the Neta 2C classification. What is Arrakis? They are caused daily by severe heating of the ground surface with cooler temperatures above and light wind. Arrakis is still quite water poor. In the earliest known phase of the planet's history, many mountain ranges and deep grabens existed in all regions of the planet. The dramatic oxygen decrease was followed by a gradual rise. Ozone is important as it is around 65 times more effective at warming the atmosphere than CO over a 20-year period. The Tyrant Leto II rules the universe from the Citadel, a fortress built in the Last Desert of the Sareer. Registration on or use of this site constitutes acceptance of our Terms of Service. We wanted to know if the physics and environment of such a world would stack up against a real climate model. One of the most interesting aspects of Arrakeen surface morphology is that the mountain chains and grabens (deep valleys) run either north-south or east-west (geographic coordinates). Kynes became so fascinated by the planet and its people that he married into a Fremen tribe, eventually being absorbed into their culture and coming to be known as a leader among the Fremen. erosion dominant. Because it is hereand only herewhere spice is found. The Fremen, traditionalist human clans, also eked out a life on the planet, existing in the caves of rocky outcrops and mountain ranges that broke up the planetwide desert. Combined with oxygen loss due to chemical reaction caused by the planet's high geological activity, the amount of oxygen dropped dramatically. The non-canon Dune Encyclopedia (1984) theorizes that the depletion of the oceans (the primary result of which was desertification) was probably caused by the impact or near miss of a comet or other quasi-planetary body. Without it there is no commerce in the Empire, there is no civilization. The Fremen typically lived in patriarchal tribes, known as sietches, which were led by a naib. 687 Earth days. The planet also gets very cold outside of the tropics, with winter temperatures that would also be uninhabitable without technology. According to the Legends of Dune prequel trilogy by Brian Herbert and Kevin J. Anderson, it was a group of Zensunni wanderers escaping slavery on the planet Poritrin who originally crashed on Dune in a prototype interstellar spacecraft several years prior to the creation of the Spacing Guild. Idaho had been the highest peak. Arrakis eventually became known as Rakis, while the city of Arrakeen became known simply as Keen. It may come as a surprise that Arrakiswasnt alwaysan inhospitable desert planet. [10], The composition was quite similar to that of other Neta 2C-53B planets except that the amount of ozone was anomalously high and that of water vapor anomalously low. However, as you move closer to the polar regions towards the cities of Arrakeen and Carthag, the climate in the book begins to change into something that might be inferred as more hospitable. We then needed to tell the climate model certain things about Arrakis, based on the detailed information found in the main novels and the accompanying Dune Encyclopedia. The day averages 22.4 standard hours; theoretical calculations show that under special circumstances the day can be as short as 3.81572 hours and as long as 51.36405 hours. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Arrakis and drainage systems are In the northern hemisphere this flow was deflected westward, in the southern hemisphere eastward (Coriolis effect, planetary designation 3). House Atreides went into hiding, but after seeking refuge with the Fremen quickly became their leaders through their inherent ability to command loyalty and through their promise that Kynes's vision would be realized through their rule. Hence most travel is by air. She thought not. The oldest rocks on Arrakis have been dated, isotopically, as being 1.1 eons old (1 eon = 1 billion standard years) and have been found only by deep drilling and only in a few places, existing as small fragments contained in much younger rock. Also, their history with cultural persecution mandated the need for combat knowledge. In the novel Paul notes, "There appears to be a linguistic connection between the Fremen and the Muadru. The sky had an almost uniform dullness due to light scattering by the dust although occasionally, more often in the polar regions, it often appeared bluish. These enormous creatures, which can grow up to 400 meters long, maintain the oxygen concentration of the Dune atmosphere. They'll portray Valya and Tula respectively, "the formidable Harkonnen Sisters, who have risen to power in the Sisterhood." Ancient water This cautionless man-made interference to the natural course of the planet proved to be catastrophic. It has 27. Our Solar System Might Have 2 Suns Watch on Mars orbits the same sun as the Earth. L.L. Within only a few centuries, these sandtrout return Arrakis (thence called 'Rakis') to a desert. Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface. An extremely dry desert environment requires plenty of water to sustain human life. This was a wet planet then. The Fremen, enchanted by Kynes's stories of large bodies of water, greenery, and mild temperatures not requiring stillsuits, followed him with fervor. The Fremen in Dune are a group of people who operate on Arrakis among the dunes and within the ruins. Leto II appointed a Planetology Commission to head a scientific task force. Over several thousand years, Arrakis was transformed into a green and temperate world much more habitable to humans, just as Kynes had hoped. The arched ceiling stood two stories above her with great crossbeams she felt sure had been shipped here to Arrakis across space at monstrous cost. In many visual media, we have seen Arrakis portrayed with a bright blue sky just like ours, and even the new adaptation seems to be going that route. From my online researchArrakis also known as Dune, and later Rakis after the fall ofGod EmperorLeto Atreides II, was a harsh desert planet located on the far edge of the OldImperiumin theCanopusstar system. These changes in rotation rate, as well as the effects of the Twins have had profound impact on the geologic evolution of Arrakis. [7], Its 1000 5 mbar mean surface pressure, mean global wind speed of 20 3 km/h and standard height, and 286 2 absolute planetary mean temperature (annualized), all are compatible with Neta 2C-53B guidelines. Save my name, email, and website in this browser for the next time I comment. Two hundred such statues could be stacked one atop the other against the entrance pillars and still fall short of the doorway's capitol arch, which itself is almost a thousand meters below the first beams upholding the lower roof. If the observed ratio of approximately one planet per star is consistent everywhere, the observable universe might contain 10^24, or 1 septillion, suns. It used to have 3, though. It covers a region about 14.6 million miles in diameter. After some 3,500 years of rule, Leto II died while crossing the Idaho River after the Guardian Wall of the Sareer opened. Finally, the Encyclopedia notes that early in the history of Arrakis, the Imperium made several attempts to terraform the planet, which resulted in an abundance of Terran desert life on the planet (such as kangaroo mice and hawks), but failed to otherwise change the environment, as the local sandtrout "encyst" any open water on the planet. The atmosphere consisted of 75.4% nitrogen, 23% oxygen[1] and negligible amounts of trace gases; given the abundance of oxygen, the atmosphere allowed human beings to live on the planet without respiratory equipment. These phenomena ancient lore recognized as the spirits of ancestors. Arrakis, also known as " Dune ", and later " Rakis " after the fall of God Emperor Leto Atreides II, is a harsh desert planet located on the far edge of the Old Imperium in the Canopus star system. Their feelings are so strong that they aren't afraid to fight for their home using guerrilla tactics to combat their more advanced enemies. With such a gravitational attraction, the light gases such as hydrogen and helium have all but escaped into space. 3. The spice. Draco's stars were circumpolar about 5000 B.C., and, like all those similarly situated, of course few in number owing to the low latitude of the Nile country, were much observed in early Egypt, although . in mountainous areas, but all in all The book says that there is no rain on Arrakis. Marine sediments indicate that the only suvivors were several protochordata species of worms (mostly of the burrowing type), several protozoa micro-organisms, varieties of plankton, including the ancestors of the shai-huludata. Breathing of course converts oxygen to carbon dioxide, and plants are the primary way that carbon dioxide is converted back into oxygen. Arrakis became the new seat of power for both the Empire and the religious jihad that Paul unleashed upon the known universe. Winters are just as extreme,. The planetary mean of crust portion displacement (with respect to other crustal segments) is 30 cm per year. On Arrakis it is 0.5 percent. Other notable sites on Arrakis throughout its history include Observatory Mountain, Mount Idaho, Dar-es-balat and the Kynes Sea. Arrakian storms were preceded by an extremely small decrease in integrated wind speed which was calculated with the use of weather poles.[11]. Once he himself begins the transformation into a human/sandworm hybrid, he eradicates all desert on Arrakis except for a small area he makes his base of operations, and destroys all of the sandworms save onehimself. The production method of atmospheric oxygen sufficient to sustain limited biological life is through sandworm metabolism, which acts like an oxygen-producing factory. Scientists have also calculated that it's about 27 million degrees Fahrenheit inside the sun's core and more than 9,000 degrees Fahrenheit on its surface. From a distance, the dimensions of this construction are deceptive [] The largest man-made structure ever built, the Grand Palace could cover more than ten of the Imperium's most populous cities under one roof, a fact that becomes more apparent when you learn Atreides attendants and their families, housed spaciously in the Palace Annex, number some thirty-five million souls [] When you walk into the Grand Reception Hall of the Palace at Arrakeen, be prepared to feel dwarfed before an immensity never before conceived. Kynes' analysis of Arrakis convinced him that the planet was once a lush and fertile world. Arrakis has two moons. As a result of the gravitational pulls of the Twins, Arrakis achieves a highly eccentric orbit, maximum ellipticity 2.1, every 12323 years. Sub-freezing temperatures occurred only at the poles. total amount is small compared to that The dramatic changes that have occurred since then were detailed by A. G. Xenach in 15029 AG. The atmospheric dust content was within the bounds of the Neta 2C-53B classification. The Spice Harvesting Tech of Dune, What is the Bene Gesserit? After the Butlerian Jihad, the powerful effects of the spice, especially with regard to space travel, quickly made it an essential resource and a focal point for the emerging Corrino Empire. This population consisted of traders and offworlders who tried to make their living through trading water or spice. Quakes are common and the amount of volcanic activity is on the high side, but not extreme. His body decomposed into sandtrout that absorbed water, eventually re-creating the conditions required for the sandworms to appear. A salt pan forms by evaporation of an ocean or lake. Paul Atreides recalls that the few plants and animals on the planet include "saguaro, burro bush, date palm, sand verbena, evening primrose, barrel cactus, incense bush, smoke tree, creosote bush kit fox, desert hawk, kangaroo mouse many to be found now nowhere else in the universe except here on Arrakis. Even after many thousands of years of study the exact mechanism by which the magnetic field is produced was not fully understood.[5]. In the science fiction novels, the temperature of the boiling point on Arrakis is 70C (or 158F). I forgot that Arrakis is called Rakis in the later books in the Dune series. The star nearest the north celestial pole is the + 9 magnitude star Yuspen. The tropical and middle latitudes of Arrakis have long growing seasons with temps ranging from 51 degrees F to 84 degrees F (11 to 29 degrees C), similar to most productive environments of Earth. Over one 2,000 year period, the Tramblisch Range rose 3,125 meters.[5]. Person with Arrakis having 3 as Personality number are ambitious & philosophical. This practice led eventually to Kynes's death, but not before leaving a legacy and a vision for the Fremen people. Grabens open, oscillate, and close at equally rapid rates. If the atmospheric conditions existed for open water, then its possible there was significant plant and more diverse animal life. However, our model does suggest that very small amounts of rainfall would occur, confined to just the higher latitudes in the summer and autumn, and only on mountains and plateaus. The terraforming of Arrakis reduced the eolian erosion, and with little in the way of water erosion, mountains are rising "rapidly" (in a geological time sense) resulting in conditions similar to the earliest phase. [3] The Twins also have highly elliptical orbits lying well outside the ecliptic plane defined by the orbit of Arrakis about Canopus.[5]. Depleted by water vapors, the planet could not sustain the remaining oceans and standng water, and they also disappeared. These included the planets topography and its orbit, which was was essentially circular, akin to the Earth today. Mt. Over the next 1,500 years, under the biological terraforming effect of the sandtrout/sandworm cycle, Arrakis gradually returned to being a desert. Cities like Arrakeen and Carthag would suffer from both heat and cold stress, like a more extreme version of parts of Siberia on Earth which can have both uncomfortably hot summers and brutally cold winters. Evidence in 12984 AG correlated ice-age-like periods with the dust cloud opacity: the peculiar velocity of Canopus carried the cloud along with the planetary system through regions of varying cloud opacity. Author admin Reading 3 min Views 16 Published by 2022. . Its mindboggling. That's roughly 168 Jupiters across, and inside is the same amount of mass as 4 million suns combined. If you paid any attention in your Junior High Earth Science class youll recall that salt pans mean there was once water. In Dune, Leto's concubine Lady Jessica has this first impression of the Great Hall: Jessica stood in the center of the hall [] looking up and around at shadowed carvings, crannies and deeply recessed windows. Scientists have also calculated that it's about 27 million degrees Fahrenheit inside the sun's core and more than 9,000 degrees Fahrenheit on its surface. In the next millennia, a survey proved a decrease in the numbers of birds and mammals, subsequently linked to a decrease in oxygen content. They must express themselves. Atmospheric pressure at the equator is 760 mm, about average for a planet of this diameter and mass. Similarly Arrakis as a bioregion is presented as a particular kind of political site. It is the home world of Squeegi01 and named after the planet in Frank Herbert's science fiction novel, Dune, which many of the waypoints on the planet derive their name from . One major difference is its source of oxygen. However, even with millennia of accumulated data, the cause of the drastic climate shift remains unknown to scientists. While the planet, Dune, is fictional, Canopus is very real and is the second-brightest star in all the heavens as seen from Earth. Maybe you've tried counting them before. But this is where the books perhaps differ the most from our model, which suggests summer temperatures would melt any polar ice, and there would be no snowfall to replenish the ice caps in winter. This story originally featured on The Conversation. Its possible that Arrakis was once a planet much like Earth. Really good to see here. Therefore, it cannot legally have suns. Each sietch resides within one of the many rocky formations that dot the sands of Arrakis. The moon surface, as you probably know, has become very bright in the last few million years and reflects sun light similar to sun screen, because of that the moon has no suns anymore. [8], The environment of the desert planet Arrakis was primarily inspired by the hydrocarbon wealthy Mexico and the Middle East. [7] The planet's orbit was roughly circular throughout historical times and the axis of rotation was directed almost perpendicular to its ecliptic plane;[3] Because of this there was very slight seasonal change,[3] or no observable seasons other than a very slight advance and retreat of the poles[8] Only the geological record and theoretical calculations tell that conditions during the past were drastically different from those later. Most grabens were filled with dust and called tidal dust basins or dust chasms by the natives. The Milky Way has a mass of 1.5 trillion suns.20Aug2019, Can moons have moons? When Paul Atreides and his mother, the Lady Jessica, crash-landed in the deep desert, they experienced just how deadly the Dune terrain can be. His research into dunes became research into desert ecology and desert cultures. Finally, in the centuries after his death, it is known as Keen, a modern (though still impressive) city to house the Priesthood of Rakis.[10]. There are numerous grabens, the greatest of which were formed by dynamic development rather than running water. Necessary cookies are absolutely essential for the website to function properly. This category only includes cookies that ensures basic functionalities and security features of the website. In astronomical terms, Arrakis is a terrestrial planet because of its solid, rocky surface roughly similar to the desert and mountainous areas on Earth. ranges had peaks exceeding 7,400 meters in elevation. These cookies do not store any personal information. Arrakis Numerology : Personality No. How many suns does a Sagittarius have? These whirls do not present a hazard to humans. A slight amount of water vapor transported between the poles during the seasonal exchange. The fight for survival on the harsh world had long dominated the Fremen's cultural identity. The two moons Krelln and Arvon cause major changes in Arrakis's rotation about its own axis (the Twins also contribute, but their effects are longterm).[3].
