'''Aurorum''', commonly known as '''earth''' or '''the world''', is a {{wp|Terrestrial planet|terrestrial planet}} orbiting the star [[X]].
'''Aurorum''', commonly known as '''''Earth''''' or '''the World''', is a {{wp|Terrestrial planet|terrestrial planet}} orbiting the Sun, or {{wp|Sun|Ilios}}. It is the fifth-largest and fifth-most-massive object in the Iliosar System, as well as the only currently known {{wp|astronomical object|celestial object}} in the Iliosar System and the known {{wp|universe}} to harbor and sustain {{wp|life}}. Additionally, it is the largest and densest of the Iliosar System's rocky planets. Aurorum constitutes a {{wp|binary planet|binary planetary system}} together with its only {{wp|natural satellite}}, the Moon or ''Luna'', that makes up 40% of the binary system's total mass and interacts with the respective other {{wp|gravity|gravitationally}}.
 
Aurorum is unique in that its surface consists partly of {{wp|liquid water}}, both as salt-water and freshwater, making up the {{wp|hydrosphere}}, and an active planetary {{wp|geology}} with mechanically rigid {{wp|tectonic plates}} constituting the {{wp|lithosphere}} above a planetary interior of a solid {{wp|Earth's inner core|inner core}}, fluid {{wp|Earth's outer core|outer core}} and convecting {{wp|mantle (geology)|mantle layer}}, active geothermal activity which produce {{wp|volcano|volcanic activity}}, {{wp|earthquake|earthquakes}} and a stable {{wp|geomagnetic field}}. This allows the planet to have developed a rich {{wp|atmosphere}} consisting mainly of {{wp|nitrogen}}, {{wp|oxygen}} and other gasses, which in turn results in the constitution of the {{wp|water cycle}}, {{wp|greenhouse effect}} and {{wp|weather}} existing as a dynamic system on Aurorum.
 
Various factors such as the aforementioned and particularly Aurorum's distance from the Sun allowed for the planet to proliferate {{wp|anaerobic organism|anaerobic}} and later {{wp|aerobic organism|aerobic life}} some 4.1 billion years ago. Since, life has evolved and thrived over long periods of Aurorum's history, spawning a plethora of {{wp|biodiversity}} and occassionally punctuated by {{wp|mass extinction|mass extinction events}}. Today, the modern {{wp|human}} (''homo sapiens'') inhabits Aurorum and has increasingly altered its {{wp|climate change|climate and atmosphere}}, {{wp|biodiversity loss|biosphere}} and {{wp|land use|surface}} in what is dubbed the "{{wp|anthropocene}}". Having ascended as a global species, it has established various {{wp|society|societies}} of {{wp|ethnic group|ethnicities}}, {{wp|religion|religions}}, {{wp|sovereign state|sovereign states}} and {{wp|ideology|ideologies}}, and made significant progress in culture, arts, sciences, economic prosperity, and quality of life.

==Etymology==
==Etymology==
The generally accepted and scientific {{wp|English language|Fallish}} name of the planet ''Aurorum'' was derived from the {{wp|Latin language|Cambran}} loanword ''aurorum'', the {{wp|genitive}} {{wp|plural}} of ''{{wp|aurum}}'', the Cambran word for {{wp|gold}} and the origin of its {{wp|chemical symbol}} "Au". The related ''{{wp|Aurora}}'' refers to {{wp|dawn}} and inherently the {{wp|goddess}} of dawn in {{wp|Roman mythology|Cambran mythology}}, announcing the renewal and arrival of ''{{wp|Sol|Ilios}}'' (the Sun) each morning, before voyaging across the sky and setting at evening; she is often seen as a {{wp|Earth goddess|personified deity}} of Aurorum itself.
The planet is commonly referred to as ''Earth'' in non-scientific circles, traced back to the {{wp|Old English|Old Fallish}} noun of ''{{wp|eorðe}}'' which translates the concept of "the ground", {{wp|soil}} and ultimately the "world" as a cohesive body. Other domestically used names for Aurorum include the {{wp|German language|Hesurian}} ''Erde'' and {{wp|Danish language|Dalish}} ''Jorden'', with every {{wp|Germanic languages|Hesurianic language}} having approximate cognates, the {{wp|Latin language|Cambran}} ''Terra'' found as cognates in almost every {{wp|Romance languages|Cambrance language}}, and the {{wp|Russian language|Dulebian}} ''Земля'' (''{{wp|Zemlya}}'') in various {{wp|Slavic languages|Pomoric}} vocabularies, all reflecting their origin to a word for "soil/ground".

Most of Aurorum's surface is subdivided into oceans, which constitute the majority of its hydrosphere, and continents, which are the planet's largest landmasses. By convention, the four oceans consist of the [[Iremic Ocean|Iremic]], [[Agric Ocean|Agric]], [[Notosian Ocean|Notosian]], and [[Caphtoric Ocean|Caphtoric]], while the five continents consist of [[Pamira]], [[Berea]], [[Caphtora]], [[Melasia and Mavronesia]], and [[Alvinia]].
Most of Aurorum's surface is subdivided into {{wp|ocean|oceans}}, which constitute the majority of its hydrosphere, and {{wp|continent|continents}}, which are the planet's largest landmasses. By convention, the four oceans consist of the [[Iremic Ocean|Iremic]], [[Agric Ocean|Agric]], [[Notosian Ocean|Notosian]], and [[Caphtoric Ocean|Caphtoric]], generally seen as parts of a continuous {{wp|world ocean}}, while the five regions considered as continents consist of [[Pamira]], [[Berea]], [[Caphtora]], [[Melasia and Mavronesia]], and [[Alvinia]]. The boundaries of the continents are also influenced, albeit often times arbitrarily, by the groupings of {{wp|state|sovereign states}} into regions defined by joint historic and or cultural heritage. By {{wp|geology|geologic}} perception, Aurorum's continents roughly correspond to the surface presence of {{wp|continental crust}}, though {{wp|continental crustal fragments}} such as various islands and continental crust {{wp|submerged continent|submerged by the ocean}} are not commonly referred to as distinct continents.
 
Due to Aurorum's vivid tectonic and other geological activity, its surface and {{wp|relief}} is made up of {{wp|ocean trench|ocean trenches}} and {{wp|graben}}, {{wp|plateau|plateaus}}, {{wp|mountain range|mountain ranges}} and other forms of {{wp|topography}}. The deepest underwater location of Aurorum's {{wp|seabed}} is the Tartarus Deep of the Alvinian Trench in the eastern Iremic Ocean, with a depth of 11,038 m (36,214 ft). Aurorum's highest mountain above {{wp|mean sea level|sea level}} is Mount X, located in the X mountain sub-range of the X and its elevation established to be 8,262 m (27,103 ft).

===Tectonic plates===
[[File:Tectonic plates map of Aurorum 10.21.png|260px|thumb|right|Map of Aurorum's defined major and minor tectonic plates, their movements and locations of current or recent volcanic activity (red dots)]]
Due to their ambiguous boundaries and mutual exertion of influence via tectonic movement and other actions, {{wp|tectonic plate|tectonic plates}} are usually determined similarly to Aurorum's continents through scientific consensus. It is agreed that there are six to seven major tectonic plates (so-called ''primary plates'') currently in existence, comprising the {{wp|lithosphere}}: the Agric, Caphtoran, Dentro-Telmerian, Pamiran (often subdivided into the Ashiric and Iremic Plates), Northern and Notosian Plates. These plates make up the majority of the planet's {{wp|continental crust|continental}} and {{wp|oceanic crust}}, though there are approximately two dozen smaller and minor plates (so-called ''secondary plates'') which inhabit spaces between the larger plates; the largest of which include the Alvinian, Appiric, Erytherian, Hahrnig, Siantric, Manatan, Mavronesian, Melasian, and Savo Plates.

===Inner Iliosar System===
The inner Iliosar System comprise the four {{wp|terrestrial planet|terrestrial planets}}, made up of {{wp|refractory (planetary science)|refractory}} materials such as {{wp|silicate|silicates}} and {{wp|metal|metals}} which from the planets' respective {{wp|crust (geology)|crusts}} and {{wp|Earth's mantle|mantles}}, as well as one {{wp|gas giant}} consisting mainly of gasses such as {{wp|hydrogen}} and {{wp|helium}}. The boundary of this region is scientifically arbitrary as there is no system feature that denotes an exact border, though all planets of the inner Iliosar System have substantial {{wp|atmosphere|atmospheres}}, no {{wp|ring system|ring systems}}, few to no {{wp|moon|moons}} and are all located within the system's {{wp|frost line (astrophysics)|frost line}}.
====Laophanes====
[[File:Venus - December 23 2016.png|200px|thumb|right|{{wp|False color|False colour}} composite of Laophanes' sunward planetary side, 2009]]
Laophanes is the closest planet to the Sun and the third-largest planet of the system (approximately 17 {{wp|Earth mass|''M''<sub>🜨</sub>}}) due to it being a {{wp|gas giant}}. The planet has no natural satellites, but a noticably short {{wp|orbital period}} of 24 days which warranted the current classification of Laophanes as a {{wp|Hot Jupiter|hot Iphias}}, as well as a {{wp|retrograde motion|retrograde orbit}}. Due to its proximity to the Sun, it remains {{wp|tidal locking|tidally locked}} with the planetary day side experiencing high stellar irradiation and a temperature difference of some 500 K in comparison to its night side. This environment allows for intense {{wp|wind}} currents, radical {{wp|Atmosphere of Earth#Stratification|atmospheric stratification}} and super-rotating equatorial {{wp|jet stream|jet streams}} and {{wp|storm|storm vortices}}. Laophanes' origin and history have not yet been explained, though the {{wp|planetary migration}} hypothesis is generally ruled to be the most likely one. It is probable Laophanes will eventually be stripped bare of its atmosphere due to {{wp|hydrodynamic escape}} and become a {{wp|chthonian planet}} some 2.3 billion years in the future.
====Maciune====
[[File:Mercury in true color.jpg|200px|thumb|right|Maciune in true colour, in 2009]]
[[File:Jupiter and its shrunken Great Red Spot.jpg|200px|thumb|right|Full disk of Iphias in natural colour, 2015]]
[[File:Saturn during Equinox.jpg|240px|thumb|right|Natural colour composite of Atiner with its extensive ring system, 2010]]
Maciune is the smallest planet in the Iliosar System, with less than 0.096 {{wp|Earth mass|''M''<sub>🜨</sub>}}, and the second-closest planet to the Sun. It is characterized by its unusually large {{wp|axial tilt}} at almost 79.2 degrees, the highest {{wp|orbital eccentricity}} of any planet in the system, and the striking outside resemblence to Luna; Maciune features a heavily cratered and rugged surface, indicating long-subsided geological activity. However, long and prominent streaks of material traversing the planet's surface, called ''{{wp|lineae}}'' (meaning "lines"), potentially indicate tectonic activity analogous to {{wp|mid-ocean ridge|mid-ocean ridges}} on Aurorum and, ultimately, {{wp|tidal heating|tidal flexing}} in the planet's distant past. Therefore, Maciune is generally agreed to have been a former and escaped moon of Laophanes, knocked out of its orbit at some point during Laophanes' migration phase. Because it is tectonically dormant and relatively small, it retains only a very faint surface-bound {{wp|exosphere}} incapable of a {{wp|greenhouse effect}} and therefore sees temperature fluctations in the range of 600 K (327 °C; 620 °F).
====Aurorum====
Aurorum, or Earth, is the third-closest planet to the Sun and the second-largest and single largest terrestrial planet in the entire and inner system respectively. It is special in that it is the only known celestial body to exhibit developed life, a liquid hydrosphere and active plate tectonic activity. Composed of a solid inner core, a liquid outer core and mantle, and a solid crust through {{wp|planetary differentiation}}, Aurorum also simultaneously is the most dense terrestrial planet and possesses the largest terrestrial {{wp|geomagnetic field}}. The presence of life radically altered the planet's atmospheric makeup through the emission of most notably {{wp|oxygen}}, {{wp|carbon dioxide}} and {{wp|methane}}, surface through {{wp|vegetation}} and {{wp|human}} activities, and the consumption of its natural {{wp|resource|resources}}. Aurorum is part of a {{wp|double planet|binary planet system}} together with its only natural satellite, Luna or the Moon, which also is the only large satellite of a terrestrial planet in the Iliosar System.
====Luna====
Luna, or the Moon, is the only natural satellite of Aurorum. With approximately two-thirds the diameter and one quarter the mass of Aurorum (0.27 ''M''<sub>🜨</sub>), Luna, as a {{wp|planetary-mass object}}, is considered to be the binary planetary partner to Aurorum, and its gravitational influence so large that the {{wp|barycenter}} of the Auroran system lies outside Aurorum, causes Aurorum's {{wp|tide|tides}} and is responsible for its {{wp|tidal acceleration}}, as is vice versa the case for Luna due to Aurorum's gravity. It lacks any noteworthy magnetic field, atmosphere or hydrosphere, and features dark {{wp|lunar maria|maria}} ("seas") of volcanic origin, {{wp|impact crater|impact craters}}, lobed {{wp|rupes}} ("cliffs") and highly variable topography. Its origin and interior are not fully understood, as its core is disproportionally large and its formation can only partly be explained by the proposed {{wp|giant-impact hypothesis}}, gravitational capture of Luna, or joint formation of Aurorum and Luna in a {{wp|circumplanetary disk}}.

Modern humans have lived most of their existence and until approximately 12,000 years ago as {{wp|hunter-gatherer|hunter-gatherers}} living in small {{wp|tribe|tribal}} societal structures. The invention of {{wp|agriculture}} with the {{wp|domestication}} of {{wp|plants}} and {{wp|lifestock}} took place in multiple areas of the world, most notably the Endotheric Sea, Yudong, Mesoalvinia, and Mavronesia, about 7,000 to 6,000 years ago, and enabled the species to abandon a lifestyle of hunting and gathering, establish permanent {{wp|settlement|settlements}} supplied by increased food production, foster the use of metal tools, and create the first {{wp|cvilisation|civilisations}}.
The development of Tayari {{wp|city-state|city-states}} on the eastern Endotheric Sea by the 3rd millenium BCE precipitated the {{wp|urban revolution}}, and witnessed the rise of other major civilisation of the time, namely the earliest Erytherian cultures and Ancient Egypt. From 3,000 to 1,200 BCE and with the onset of the {{wp|Bronze Age}}, maritime trade was facilitated between the Endotheric civilisations and inventions such as wheels, sail, plows, and {{wp|cuneiform|cuneiform script}} were made while the {{wp|science|sciences}}, {{wp|astronomy}} and {{wp|mathematics}} were introduced and furthered. Tayar formed the first {{wp|colonial empire}} of the ancient world, the [[Chasun#History|Horyo dynasty]] rose to prominence, and by 1,000 BCE iron started to replace bronze as the dominant working material with the {{wp|Iron Age}}. The flourishing of Ancient Erytheria replaced the dwindling Tayari civilisation and introduced concepts such as {{wp|democracy}}. In 400 BC, the [[Cambran Republic]] and subsequent [[Cambran Empire]] came to rise and dominate the Endotheric Sea and the [[Yudong|Mong dynasty]] saw Yudong's {{wp|golden age}}.

Aurorum, commonly known as Earth or the World, is a terrestrial planet orbiting the Sun, or Ilios. It is the fifth-largest and fifth-most-massive object in the Iliosar System, as well as the only currently known celestial object in the Iliosar System and the known universe to harbor and sustain life. Additionally, it is the largest and densest of the Iliosar System's rocky planets. Aurorum constitutes a binary planetary system together with its only natural satellite, the Moon or Luna, that makes up 40% of the binary system's total mass and interacts with the respective other gravitationally.

Aurorum is unique in that its surface consists partly of liquid water, both as salt-water and freshwater, making up the hydrosphere, and an active planetary geology with mechanically rigid tectonic plates constituting the lithosphere above a planetary interior of a solid inner core, fluid outer core and convecting mantle layer, active geothermal activity which produce volcanic activity, earthquakes and a stable geomagnetic field. This allows the planet to have developed a rich atmosphere consisting mainly of nitrogen, oxygen and other gasses, which in turn results in the constitution of the water cycle, greenhouse effect and weather existing as a dynamic system on Aurorum.

Various factors such as the aforementioned and particularly Aurorum's distance from the Sun allowed for the planet to proliferate anaerobic and later aerobic life some 4.1 billion years ago. Since, life has evolved and thrived over long periods of Aurorum's history, spawning a plethora of biodiversity and occassionally punctuated by mass extinction events. Today, the modern human (homo sapiens) inhabits Aurorum and has increasingly altered its climate and atmosphere, biosphere and surface in what is dubbed the "anthropocene". Having ascended as a global species, it has established various societies of ethnicities, religions, sovereign states and ideologies, and made significant progress in culture, arts, sciences, economic prosperity, and quality of life.


Etymology

The generally accepted and scientific Fallish name of the planet Aurorum was derived from the Cambran loanword aurorum, the genitive plural of aurum, the Cambran word for gold and the origin of its chemical symbol "Au". The related Aurora refers to dawn and inherently the goddess of dawn in Cambran mythology, announcing the renewal and arrival of Ilios (the Sun) each morning, before voyaging across the sky and setting at evening; she is often seen as a personified deity of Aurorum itself.

The planet is commonly referred to as Earth in non-scientific circles, traced back to the Old Fallish noun of eorðe which translates the concept of "the ground", soil and ultimately the "world" as a cohesive body. Other domestically used names for Aurorum include the Hesurian Erde and Dalish Jorden, with every Hesurianic language having approximate cognates, the Cambran Terra found as cognates in almost every Cambrance language, and the Dulebian Земля (Zemlya) in various Pomoric vocabularies, all reflecting their origin to a word for "soil/ground".

Physical characteristics

Oceans and continents

Map showing the oceans and continents of Aurorum

Most of Aurorum's surface is subdivided into oceans, which constitute the majority of its hydrosphere, and continents, which are the planet's largest landmasses. By convention, the four oceans consist of the Iremic, Agric, Notosian, and Caphtoric, generally seen as parts of a continuous world ocean, while the five regions considered as continents consist of Pamira, Berea, Caphtora, Melasia and Mavronesia, and Alvinia. The boundaries of the continents are also influenced, albeit often times arbitrarily, by the groupings of sovereign states into regions defined by joint historic and or cultural heritage. By geologic perception, Aurorum's continents roughly correspond to the surface presence of continental crust, though continental crustal fragments such as various islands and continental crust submerged by the ocean are not commonly referred to as distinct continents.

Due to Aurorum's vivid tectonic and other geological activity, its surface and relief is made up of ocean trenches and graben, plateaus, mountain ranges and other forms of topography. The deepest underwater location of Aurorum's seabed is the Tartarus Deep of the Alvinian Trench in the eastern Iremic Ocean, with a depth of 11,038 m (36,214 ft). Aurorum's highest mountain above sea level is Mount X, located in the X mountain sub-range of the X and its elevation established to be 8,262 m (27,103 ft).

Tectonic plates

Map of Aurorum's defined major and minor tectonic plates, their movements and locations of current or recent volcanic activity (red dots)

Due to their ambiguous boundaries and mutual exertion of influence via tectonic movement and other actions, tectonic plates are usually determined similarly to Aurorum's continents through scientific consensus. It is agreed that there are six to seven major tectonic plates (so-called primary plates) currently in existence, comprising the lithosphere: the Agric, Caphtoran, Dentro-Telmerian, Pamiran (often subdivided into the Ashiric and Iremic Plates), Northern and Notosian Plates. These plates make up the majority of the planet's continental and oceanic crust, though there are approximately two dozen smaller and minor plates (so-called secondary plates) which inhabit spaces between the larger plates; the largest of which include the Alvinian, Appiric, Erytherian, Hahrnig, Siantric, Manatan, Mavronesian, Melasian, and Savo Plates.

Inner Iliosar System

The inner Iliosar System comprise the four terrestrial planets, made up of refractory materials such as silicates and metals which from the planets' respective crusts and mantles, as well as one gas giant consisting mainly of gasses such as hydrogen and helium. The boundary of this region is scientifically arbitrary as there is no system feature that denotes an exact border, though all planets of the inner Iliosar System have substantial atmospheres, no ring systems, few to no moons and are all located within the system's frost line.

Laophanes

Laophanes is the closest planet to the Sun and the third-largest planet of the system (approximately 17 M🜨) due to it being a gas giant. The planet has no natural satellites, but a noticably short orbital period of 24 days which warranted the current classification of Laophanes as a hot Iphias, as well as a retrograde orbit. Due to its proximity to the Sun, it remains tidally locked with the planetary day side experiencing high stellar irradiation and a temperature difference of some 500 K in comparison to its night side. This environment allows for intense wind currents, radical atmospheric stratification and super-rotating equatorial jet streams and storm vortices. Laophanes' origin and history have not yet been explained, though the planetary migration hypothesis is generally ruled to be the most likely one. It is probable Laophanes will eventually be stripped bare of its atmosphere due to hydrodynamic escape and become a chthonian planet some 2.3 billion years in the future.

Maciune is the smallest planet in the Iliosar System, with less than 0.096 M🜨, and the second-closest planet to the Sun. It is characterized by its unusually large axial tilt at almost 79.2 degrees, the highest orbital eccentricity of any planet in the system, and the striking outside resemblence to Luna; Maciune features a heavily cratered and rugged surface, indicating long-subsided geological activity. However, long and prominent streaks of material traversing the planet's surface, called lineae (meaning "lines"), potentially indicate tectonic activity analogous to mid-ocean ridges on Aurorum and, ultimately, tidal flexing in the planet's distant past. Therefore, Maciune is generally agreed to have been a former and escaped moon of Laophanes, knocked out of its orbit at some point during Laophanes' migration phase. Because it is tectonically dormant and relatively small, it retains only a very faint surface-bound exosphere incapable of a greenhouse effect and therefore sees temperature fluctations in the range of 600 K (327 °C; 620 °F).

Aurorum

Aurorum, or Earth, is the third-closest planet to the Sun and the second-largest and single largest terrestrial planet in the entire and inner system respectively. It is special in that it is the only known celestial body to exhibit developed life, a liquid hydrosphere and active plate tectonic activity. Composed of a solid inner core, a liquid outer core and mantle, and a solid crust through planetary differentiation, Aurorum also simultaneously is the most dense terrestrial planet and possesses the largest terrestrial geomagnetic field. The presence of life radically altered the planet's atmospheric makeup through the emission of most notably oxygen, carbon dioxide and methane, surface through vegetation and human activities, and the consumption of its natural resources. Aurorum is part of a binary planet system together with its only natural satellite, Luna or the Moon, which also is the only large satellite of a terrestrial planet in the Iliosar System.

Luna

Luna, or the Moon, is the only natural satellite of Aurorum. With approximately two-thirds the diameter and one quarter the mass of Aurorum (0.27 M🜨), Luna, as a planetary-mass object, is considered to be the binary planetary partner to Aurorum, and its gravitational influence so large that the barycenter of the Auroran system lies outside Aurorum, causes Aurorum's tides and is responsible for its tidal acceleration, as is vice versa the case for Luna due to Aurorum's gravity. It lacks any noteworthy magnetic field, atmosphere or hydrosphere, and features dark maria ("seas") of volcanic origin, impact craters, lobed rupes ("cliffs") and highly variable topography. Its origin and interior are not fully understood, as its core is disproportionally large and its formation can only partly be explained by the proposed giant-impact hypothesis, gravitational capture of Luna, or joint formation of Aurorum and Luna in a circumplanetary disk.

Ancient history and antiquity

Modern humans have lived most of their existence and until approximately 12,000 years ago as hunter-gatherers living in small tribal societal structures. The invention of agriculture with the domestication of plants and lifestock took place in multiple areas of the world, most notably the Endotheric Sea, Yudong, Mesoalvinia, and Mavronesia, about 7,000 to 6,000 years ago, and enabled the species to abandon a lifestyle of hunting and gathering, establish permanent settlements supplied by increased food production, foster the use of metal tools, and create the first civilisations.

The development of Tayari city-states on the eastern Endotheric Sea by the 3rd millenium BCE precipitated the urban revolution, and witnessed the rise of other major civilisation of the time, namely the earliest Erytherian cultures and Ancient Egypt. From 3,000 to 1,200 BCE and with the onset of the Bronze Age, maritime trade was facilitated between the Endotheric civilisations and inventions such as wheels, sail, plows, and cuneiform script were made while the sciences, astronomy and mathematics were introduced and furthered. Tayar formed the first colonial empire of the ancient world, the Horyo dynasty rose to prominence, and by 1,000 BCE iron started to replace bronze as the dominant working material with the Iron Age. The flourishing of Ancient Erytheria replaced the dwindling Tayari civilisation and introduced concepts such as democracy. In 400 BC, the Cambran Republic and subsequent Cambran Empire came to rise and dominate the Endotheric Sea and the Mong dynasty saw Yudong's golden age.
