Tau Ceti is a stable G-class main-sequence star located approximately 11.9 LY away from Sol. Tau Ceti is smaller than Sol, at 78% of its mass. However, it is also spectrally similar to Sol. There are several small, rocky planets orbiting Tau Ceti. Most of them are nearly completely metal-deficient. Three of them are within the circumstellar habitable zone of Tau Ceti. There are six main planets orbiting the star. Outside of the main planetary orbits is a large, thick disc composed of dust and rocky material left over from the formation of the planets. This disc is approximately 49.1 AU from Tau Ceti, and extends for another 55.4 AU outward. Due to the high density of relatively large pieces of rocky debris in this disc, the system’s outer planets face a threat of regular bombardment. At 236.294 AU, a very small seventh planet is engaged in a nearly circular orbit around the star. Much, much further out from the star, at approximately 0.4 LY, there exists a sphere of debris. The debris in this sphere is composed of much larger pieces than the inner disk. The asteroids orbiting in this sphere are extremely large, many even approaching the size of planetoids. The debris here is rich in hydrogen, frozen water, precious and semi-precious metals, radioactive materials, and plasma. The secondary belt extends from 0.4 LY to 1.2 LY away from Tau Ceti. The materials that are mined from this outer belt is enough to not only sustain the civilizations of inner planets, but to establish them as major exporters of raw materials.
Tau Ceti is a system located in close proximity of Sol, and serves as the main base of operation for the megacorporation [[Nanotrasen Corporation|NanoTrasen]]. First settled in the mid 2100s, it houses three colonized planets, as well as two uninhabited ones.
==System Information==
Tau Ceti is governed by the [[Republic of Biesel]], a young Republic that became independent of the economically troubled Sol Alliance in 2452 due to heavy pressure by Nanotrasen. There is still resentment in the Sol Alliance over the loss of such a wealthy system, while Nanotrasen continues to have a heavy hand in all levels of Tau Ceti.

=== Biesel ===
Main articles: [[Biesel]], [[Mendell City]]
[[File:biesel3.jpg|thumb|245px|The cityscape of Mendell City, displaying Biesel's high level of urban development.]]
The third closest planet to Tau Ceti's star, Biesel is an Earth analog which benefits from a temperate climate and breathable atmosphere. Water represents 56% of the planet's surface.
'''Settled Planets/Planetoids:''' 2 major; numerous minor settlements in Romanovich Cloud
Biesel is the central population hub for Tau Ceti, with many large cities and a registered surface population approaching 2.5 billion. All settlements on Biesel were built with a goal of sustainable development in mind, so the threat of impending environmental disaster due to overpopulation or pollution is relatively nonexistent. Most of the equator of Biesel has been set aside for agricultural purposes, given the mild climate. The planetary capital of Biesel is [[Mendell City]], a megalopolis in the southeastern quadrant of the planet. In orbit around Biesel, and its moon Valkyrie, are many multipurpose space stations, including orbital defense platforms and shipyards In a high orbit around the planet is Nanotrasen's Tau Ceti Branch Central Command Platform, the [[NSS Odin]], where [[bluespace]] shuttles depart from and return to as they move personnel between the various Nanotrasen installations around Tau Ceti. The combined population of spacers around Biesel approaches 222 million.
'''Overall Development Level:''' Very High
Biesel is primarily a financial and agricultural center, with most of it's citizens working in it's service industry or commuting to New Gibson. Tourism is a major source of income, with visitors being drawn to Biesel's sprawling shopping centers and national parks alike.
=== New Gibson ===
Main article: [[New Gibson]]
[[File:newgibson.jpg|thumb|245px|New Gibson's capital, the Hengsha Arcology]]
Considered an ice world due to its location just outside the outer edge of the habitable zone of its parent star, producing very cold temperatures, New Gibson is the industrial powerhouse of Tau Ceti. As the atmosphere on New Gibson is too thin to support life, all of its population lives under biodomes.
'''Total Population (est.):''' 2,920,261,717
The planet is a prime location for industrial development, since minimal terraforming is required, and populations of workers can be sustained in biodomes scattered across the barren landscape. Any activity on the planet's surface requires EVA equipment, but due to its high level of industrial development, the planet is the largest producer of consumer appliances, ship components, space station modules, and other manufactured goods in Tau Ceti.
'''Military Presence:''' Moderate to Heavy
The planetary capital of New Gibson is the [[Hengsha Arcology]], or simply Hengsha, a self-contained complex mimicking the landscape of Biesel, complete with parks, waterfalls and wildlife. While New Gibson has a complex dedicated to virtually all industries, from personal grooming equipment to advanced AI components, it's major industries are shipbuilding, construction materials, enterprise-scale medical equipment and electronics.
'''Points of Interest:''' NanoTransen Administrative Corporate Park, Tau Ceti Warp Gate, First Instestellar War Memorial, Hengsha Arcology, Mendell Space Elevator, Gibson Space Elevator, Arcadia National Park, Biesel-Harper Station, Aaliyah Galleria Super-Mall
=== Luthien ===
Main article: [[Luthien]]
[[File:luthien.jpg|thumb|245px|One of numerous research outposts around the Luthien northern sea.]]
Placed within the inner reach of Tau Ceti's habitable zone, Luthien is a desert planet with a thin, unbreathable atmosphere and small amounts of liquid water located around its cooler poles. The small amounts of human habitation are found near the north and south polar seas, and constitute of controlled-environment biodomes and research stations.
==Planets and Major Bodies in Orbit==
Luthien is the site of many testing and research facilities, such as those dedicated to weapons testing, or the development of flora and fauna that are able to adapt to extreme environments.
===Caprice (τCet b)===
=== Caprice ===
'''Development level''': None
The closest planet to Tau Ceti's star, caprice is a barren world completely devoid of life. The harsh surface conditions prove hostile for all attempts of exploration, and even advanced scientific equipment cannot survive in its extreme environment for long without breaking down.
'''Population (est.)''': Uninhabited
=== Reade ===
The furthest of the five planets of Tau Ceti, Reade, is a small planet entirely devoid of atmosphere, water, or useful minerals. Mostly ignored by the rest of the system's population, it is nevertheless rumored to harbor pirate outposts on the planet surface. Civilian travel is discouraged past this point of the system.
Similar to the planet Mercury in orbit around Sol, Caprice is a small world that orbits very close to its parent star. The periapsis and apoapsis of the planet’s orbit range from 0.203 AU to 0.291 AU, respectively. The planet's orbit is also extremely fast, with a Caprician year only lasting approximately 99 standard days. On the other hand, Caprice has very slow revolution speed; a Caprician day lasts around 49 standard days. The planet was named Caprice because of the extreme differences in temperature it experiences, similar to Mercury. The side of Caprice that faces Tau Ceti has temperatures that regularly exceed 500 °C, and the side that faces away experiences temperatures around -180 °C. Caprice is completely inhospitable to organic life of any kind. Even advanced scientific equipment cannot survive in its extreme environment for long without breaking down. Caprice has no detectable atmosphere. With a mass of 257.6E21 Kg, its gravity is too insignificant to trap gases and keep them from being swept away by the solar wind given off by Tau Ceti. Civilian travel is not advised.
== Other Bodies ==
===Luthien (τCet c)===
=== Chandras ===
'''Development level:''' Medium; Biodomes
Chandras is an icy body in distant orbit of Tau Ceti. Although its surface contains lakes of liquid nitrogen, it is entirely metal-deficient, and possessing no infrastructures to speak of, is uninhabited and of low interest for the system.
'''Population:''' 20,346
=== The Dust Belt ===
Past Chandras, the Dust Belt is a thick ring of debris encircling Tau Ceti's solar plane and enclosing its inner planets. Debris vary in size ranging from microscopic dust particles to large asteroids the size of small moons. Contrary to popular belief, travel through the Dust Belt does not pose a major risk to spaceships, although the danger of rogue asteroids has discouraged mining operations from setting up in the area.
Luthien is the second planet in the Tau Ceti system. Its orbit ranges from a periapsis of 0.687 AU to an apoapsis of 0.694 AU. Its orbit places it just within the inner reach of Tau Ceti's habitable zone, and allows liquid water to exist near the poles of the planet. However, most of the planet's landscape is harsh, uninhabitable desert. The poles of the planet are covered in shallow seas filled with simple algae and single-celled organisms. A Luthienese year lasts for 256 standard days, and a Luthienese day is approximately 22.7 standard hours long. Luthien has a thin atmosphere composed of 65% carbon dioxide, 10% nitrogen, 12% oxygen, 3% water vapor, and the remaining 10% distributed among various trace and noble gases. The atmosphere does not allow unprotected activity on the surface of the planet, and the only human habitation is near the poles in controlled-environment biodomes and research outposts. Temperatures on Luthien can range from 237 °C near the equator, to 89 °C near the poles. Having a mass similar to Mars (627E21 Kg) and being almost completely metal-deficient, Luthien has a relatively low amount of gravity, at 0.510 Earth gravity. Luthien is the site of many testing and research facilities, such as those dedicated to weapons testing, or the development of flora and fauna that are able to adapt to extreme environments.
=== Dumas ===
Dumas is an extremely small rocky body that orbits within the far reaches of Tau Ceti - obscured almost entirely by the dust belt, one of its defining features is an almost complete lack of light, resulting in temperatures nearing the absolute zero. It is rumored that smugglers may be using stations in orbit of Dumas to move goods in and out of the Tau Ceti system.
===Biesel (τCet d)===
=== The Romanovich Cloud ===

'''Development level''': High; Open Megacities, Space Stations, Developed Infrastructure
Main article: [[Romanovich Cloud]]
'''Capital:''' Mendell City
The Romanovich Cloud is a shell of icy, rocky and metallic bodies that orbit very distant Tau Ceti, past even the Dust Belt. Rich in deposits of precious and semi-precious metals as well as radioactive elements, the Romanovich Cloud is the source of nearly all the raw materials used within Tau Ceti.
'''Terrestrial Population (est.)''': 2,485,308,432
The cloud is also the only known source of [[Plasma]], a volatile but highly-sought after compound, known for its uses in the biomedical and energy industries. Most of the sources of Plasma within the Romanovich Cloud are under control of [[Nanotrasen Corporation|NanoTrasen]], which has consequently established many high-tech research facilities in the area in the past few years.
'''Spacer Population (est.)''': 221,739,109
Biesel is considered something of a rarity in the field of astronomical physics. Not only is it an Earth analog, but its orbit is at a 34° angle to Tau Ceti's solar plane. This means that unlike the other planets in the Tau Ceti system, it is only at an increased risk for asteroid bombardment when it aligns with the solar plane at two points in its orbit. The orbit of Biesel is a nearly circular 0.857 AU away from its parent star, providing Biesel with a comfortable, mild climate. It is located near the middle of Tau Ceti's habitable zone, and due to the smaller mass of its parent star and is considerably cooler than Earth. Approximately 56% of the planet's surface is covered in liquid water, and 28% of it is fresh. A Bieselian day lasts approximately 24.9 standard hours, and a Bieselian year is about 1.2 standard years long.
Biesel is the central population hub for Tau Ceti, with many large cities and a registered surface population of around 2.5 billion. All settlements on Biesel were built with the goal of sustainable development in mind. Biesel is often touted as a prime example of 'green development', able to support billions of people while keeping its natural ecosystems largely intact. Most of the equator of Biesel, with it's warmer climate, has been set aside for agricultural purposes.
The planetary capital of Biesel is Mendell City, a megalopolis in the southeastern quadrant of the planet. In orbit around Biesel, and its moon Valkyrie, are many multipurpose space stations, including orbital defense platforms and shipyards. In a high orbit around the planet is Nanotrasen's Tau Ceti Branch Central Command Platform, where bluespace shuttles depart from and return to as they move personnel between the various Nanotrasen installations in orbit around Tau Ceti. The combined population of spacers around Biesel approaches 222 million.
Biesel is a major financial center, with most public companies in known space trading on the Mendell City Stock Market. NanoTransen has established it's Headquarters in Mendell City in the NanoTransen Administrative Corporate Park, a massive arcology complex where a million employees work and about one hundred thousand live.
As a naturally habitable planet, Biesel boasts a large agricultural industry. Genetically modified strains of crops and livestock as well as vertical agriculture allow the planet to produce far more food than in consumes. Biesel is one of the largest exporters of raw food in the known galaxy. Additionally, tourism is a major source of income. Visitors are drawn to Biesel's sprawling shopping centers, lively nightlife and serene national parks.
===New Gibson (τCet e)===
[[Image:Space_elevator.png|thumb|500px|A view of a space elevator connecting an orbital platform to the Raymer Industrial Complex on New Gibson.]]
'''Development level''': High; Closed Cities, Space Stations, Industrial Mega-parks
'''Terrestrial Population (est.)''': 201,537,001
'''Spacer Population (est.)''': 11,656,829
New Gibson is the industrial powerhouse of Tau Ceti. It is located just outside the outer edge of the habitable zone of its parent star, and is therefore very cold. The planet's orbits at a distance of approximately 1.56 AU. There is no liquid water on New Gibson, all of it locked up in permafrost and polar glaciers. The atmosphere is too thin to support life. All inhabitants of New Gibson live inside regulated environments within biodomes. New Gibson revolves very slowly, almost to the point of being tidally locked to Tau Ceti. A day on New Gibson lasts approximately 4.9 standard years, almost as long as a New Gibson year, which is 5 standard years. Due to its distance from its parent star, New Gibson is in a permanent ice age. Temperatures dip down to -194 °C, and do not rise above -65 °C. However, despite being a harsh and unforgiving environment unsuited for organic life, it has a population of about 202 million. The planet's complete lack of tectonic activity and weathering agents such as rivers and precipitation means that the surface of the planet is extremely flat; New Gibson has no major mountains or valleys except near the poles, where the action of glaciers carves indentations.
The planet is a prime location for industrial development, since minimal terraforming is required, and populations of workers can be sustained in biodomes scattered across the barren landscape. Any activity on the planet's surface requires EVA equipment, but due to its high level of industrial development, the planet is the largest producer of consumer appliances, ship components, space station modules, and other manufactured goods in Tau Ceti. The planet’s gravity is rather weak, at 0.302 Earth gravity. However, this heavily reduces the costs of transportation. New Gibson has three moons, simply designated τCet eI, τCet eII, and τCet eIII. The moons have been transformed into transport hubs for massive cargo ships. Shipments of manufactured components are lifted into orbit around the planet and maneuvered into the transport hubs on the moons, where they are loaded into cargo ships for transportation to other planets and systems. The surface of New Gibson is divided into 127 different districts, all geared towards different industries.
The planetary capital of New Gibson is the Hengsha Arcology, or simply Hengsha, a self-contained complex mimicking the landscape of Biesel, complete with parks, waterfalls and some wildlife. While New Gibson has a complex dedicated to virtually all industries, from personal grooming equipment to advanced AI components, it's major industries are shipbuilding, construction materials, enterprise-scale medical equipment and electronics. New Gibson is mostly self-sufficient but buys luxury food items from Biesel. Tensions have risen after the establishment of the 'Free Trade Zone', which mandated that NanoTransen be sold at a minimum 10% of New Gibson's exports across multiple industries (including AI components and construction materials). New Gibson suffers from increased unrest and rising crime rates, where competing pro- and anti-NanoTransen camps are more aggressive and outspoken than on Biesel.
===Reade (τCet f)===
'''Development level''': Low to None
'''Terrestrial Population (est.)''': Unknown; suspected in the low hundreds or dozens, likely temporary
Reade is a small, cold ball of rock that orbits Tau Ceti at a distance ranging between 19.523 AU to 23.980 AU. It has no atmosphere to speak of, and is only slightly larger than Pluto, just large enough to call it a planet, rather than a planetoid. It has no moons, no tectonic forces, or any water. It is also completely devoid of useful minerals. The surface temperature can range between -200 °C to -150 °C. A Readen day is very long, lasting nearly 563 standard days. A Readen year is also very long as well, stretching 98 standard years. It is generally ignored by the rest of Tau Ceti, although it is rumored that there are pirate outposts located on the planet. Civilian travel is not advised.
===Chandras (τCet h)===
'''Development level''': None
'''Terrestrial Population''': Uninhabited
Chandras is an icy body that orbits Tau Ceti at a distance ranging from 31.233 AU to 35.756 AU. It has no atmosphere, a result of its very low mass (98E21 Kg) and associated low gravity (0.213 Earth gravity). Completely metal deficient, there exists no infrastructure on or around the planet. The surface is completely coated in ice, with scattered lakes of liquid nitrogen. Surface temperatures do not vary much, almost always staying at around -210 °C. Chandras faces an extremely high risk of asteroid bombardment. A Chandran day lasts 34 standard days, and a Chandran year is as long as 112.3 standard years. The planet is ignored by the rest of Tau Ceti. Civilian travel is not advised.
===The Dust Belt===
The Dust belt is a thick ring of debris encircling Tau Ceti's solar plane, and enclosing the inner planets. It has a radius of 55.4 AU, and is composed of debris of various sizes, ranging from microscopic dust particles to large asteroids the size of small moons. The Dust Belt is metal deficient and has proven too dangerous to mine effectively. The lack of materials present in the belt and the danger of rogue asteroids has discouraged further mining operations after the initial forays. Civilian travel is not advised.
===Dumas (τCet i)===
'''Development level''': Low to None
'''Spacer Population (est.)''': Unknown, suspected in the low hundreds
Dumas is an extremely small rocky body that orbits in a nearly perfect circle around Tau Ceti. It resides at 236.294 AU, and its periapsis and apoapsis differ by only 0.000001 AU. Much of the light from Tau Ceti that would fall upon Dumas is blocked by The Dust Belt, resulting in surface temperatures that approach absolute. Dumas is tidally locked to Tau Ceti and has an orbital period of approximately 283 standard years. Dumas is rumored to have orbital stations used by smugglers to move goods into Tau Ceti. Civilian travel is not advised.
===The Romanovich Cloud===
The Romanovich Cloud is a shell of icy, rocky and metallic bodies that orbit Tau Ceti from a distance of 250 AU to a distance of 1.7 LY. The Cloud was discovered by astronomer Solomon Romanovich and was named after him. The Cloud is composed of large pieces of debris left over from the origins of the Tau Ceti system, similar to the Oort Cloud around Sol. It is currently unknown how the Romanovich Cloud formed, since there are no gas giants presently in orbit around Tau Ceti. Several theories suggest that gas giants may have existed in the distant past, and that they either grew to a point that they were crushed under their own gravity and imploded, or gained enough momentum to reach an escape velocity. The Romanovich Cloud is the source of nearly all of the raw materials used in Tau Ceti. The rocky bodies within it are rich in deposits of precious and semi-precious metals, radioactive elements, and the mysterious substance dubbed Plasma. The corporate entity Nanotrasen has claimed most of the plasma deposits in the Romanovich Cloud for itself, erecting mining facilities and patrolling the nearby space with automated drones and FTL capable battleships. Many high-tech Nanotrasen facilities are located in the Romanovich Cloud, such as the NSS Aurora, a cutting-edge science station located above the solar plane of Tau Ceti. The Romanovich Cloud is actually larger than Sol’s Oort Cloud. It marks the outer edge of the Tau Ceti system.
Tau Ceti is a system located in close proximity of Sol, and serves as the main base of operation for the megacorporation NanoTrasen. First settled in the mid 2100s, it houses three colonized planets, as well as two uninhabited ones.
Tau Ceti is governed by the Republic of Biesel, a young Republic that became independent of the economically troubled Sol Alliance in 2452 due to heavy pressure by Nanotrasen. There is still resentment in the Sol Alliance over the loss of such a wealthy system, while Nanotrasen continues to have a heavy hand in all levels of Tau Ceti.
