'''Kylaris''', commonly known as '''earth''', is a rocky planet in the Solaris star system. It completes an orbit around Solaris approximately every 365.2422 calendar days (rotations about its axis); from the perspective of the North Pole on the planet, like most other celestial bodies in the star system, it orbits counterclockwise. It is spherical with a slight bulge at the equator owing to its rotation, which is slightly tilted compared to its orbital axis with respect to the sun, and it has one planetoid moon.

The planet is believed to have formed conventionally, several billion years ago, from the heavier elements in the accretion disk of the sun; the presence of these elements mean that Solaris is at youngest a second-generation star. Distinct layers formed over time, as accretion slowed and the planet cooled.  
The planet is believed to have formed several billion years ago from the heavier elements in the accretion disk of the sun; the presence of these elements mean that Solaris is at youngest a second-generation star. Distinct layers formed over time as accretion slowed and the planet cooled. The planet has a metallic core, which creates a magnetic field around the planet. This is surrounded by a mostly liquid mantle composed of various metallic and nonmetallic elements, silicon being the most common. The outermost layer is the solid crust, or lithosphere, which is thin but encompasses the entire planet. It is composed of generally lighter materials than the mantle. The planet's active tectonics are highly influential on its topography and biosphere.

The outermost layer is the solid crust, or lithosphere, which is thin but encompasses the entire planet, being composed of similar but generally lighter materials than the mantle. Most of the planet's surface area is covered in liquid water oceans, with the dry parts constituting land. The atmosphere is primarily nitrogen, with a significant fraction of oxygen; most other components of the atmosphere are trace, including argon and carbon dioxide. The atmosphere can be divided into layers depending on altitude, and is thick enough to burn up the vast majority of objects which fall into it. The active tectonics and energetic atmosphere of the planet are notable, and highly influential on its topography, biosphere, etc.

All known life is native to the planet, with rough estimates of millions of species and octillions of individual lifeforms. It is thought to have been present for around half of the planet's existence. The biosphere is believed to be constrained to the crust, the lower atmosphere, and possibly the upper mantle. The only known species to have exited the atmospheric strata are humans, who are generally considered the dominant species.  
The majority of Kylaris's surface is uninhabitable. Three-quarters is covered by oceans and other bodies of water. Of the quarter that is land, nearly half is uninhabitable desert, mountains, or ice caps. Only an estimated one-eighth of Kylaris's surface is considered habitable by humans. Although the range of permanent human settlement is limited by geography, modern technology has allowed humans to establish small outposts in even the most challenging environments. [[George_Ruset_Land#Settlements|Suqquirut]] in [[George Ruset Land]] is the northernmost permanent settlement in the world, and the southernmost is the South Pole Station located at the South Pole on the continent of [[Glacia]].


Human influence stretches across the overwhelming majority of the planet's surface, though most significantly on land, and their activities have a significant impact on both the biotic and abiotic world, whether with reference to atmospheric composition, land cover, hydrology, light or the transportation and transformation of terrestrial material. Most of this is a development of the last three millennia, though humans have been around for millions of years. Human societies are highly complex and organised, with the development of dozens of nation-states of varying size, often considered to be the basic social unit of organisation (some of the most significant include [[Gaullica]], [[Xiaodong]] and [[Senria]]. There are also many multinational organisations, some of which are limited to subsets of nation-states, forming blocs; these include the [[Euclean Community]], [[Rongzhuo Strategic Protocol Organisation]], [[Asterian Development Council]] and [[Council for Mutual Security and Development|COMSED]], while others are globalised, such as the [[Community of Nations]]. Significant human developments include language, of which there are thousands, organised conflict or war (such as the [[Great War (Kylaris)|Great War]]), and techniques for manipulating other species, physical energy and matter, including electrical theory, mining, agriculture and construction. These technologies have produced the dominance of the human species in recent history and improvements in the human condition: metrics by which this can be seen include the human population doubling several times, total energy consumption multiply by even more times, the extension of lifespan, and utilisation of a greater fraction of the planet's natural resource stocks on both a per capita and absolute basis.

The surface of the planet is the most complex and well-studied part of it, in particular the sections not covered by the oceans. One widely accepted way of spatially organising the planet is by dividing it into continents, which are the largest sections of land, and oceans, which are the largest sections of water.  
Kylaris's surface is customarily divided into five continents—[[Euclea]], [[Coius]], [[Asteria Superior]], [[Asteria Inferior]], and [[Glacia]]—and four oceans: the [[Lumine Ocean]], [[Vehemens Ocean]], [[Boreal Ocean]], and [[Glacial Ocean]]. The continents can be divided into subcontinents that share cultural and geographic affinity. Coius, in particular, is strongly regional, and is usually divided into [[Bahia]], [[Rahelia]], [[Satria]], [[Southeast Coius]], and [[South Coius]].

Etymology

Two photos of Kylaris from space; the left image shows the continents of Euclea and Coius, the right image the Asterias.

The commonly accepted Estmerish name for the planet, Kylaris, is a Piraean loanword, from Κυλάρις, kylaris. Kylaris was the name of the Piraean goddess of nature. She was adopted into the Solarian pantheon where she was also known as Terra, resulting in the use of terra as a name for the planet in Solarian and its derivative languages.

The planet is commonly referred to as earth, another modern Estmerish word, in media and conversation. The word is derived from the Old Swathish eorðe. Similar to Kylaris and Terra, Earth was the goddess of the human world in Weranic paganism.

Physical geography

Continents and oceans

Kylaris's surface is customarily divided into five continents—Euclea, Coius, Asteria Superior, Asteria Inferior, and Glacia—and four oceans: the Lumine Ocean, Vehemens Ocean, Boreal Ocean, and Glacial Ocean. The continents can be divided into subcontinents that share cultural and geographic affinity. Coius, in particular, is strongly regional, and is usually divided into Bahia, Rahelia, Satria, Southeast Coius, and South Coius.

Human geography

Anatomically modern humans have lived for at least 300,000 years, and human activities have greatly impacted the planet's land and water, atmosphere, and biosphere. Most of these changes have occurred over the last three millennia since the rise of urban civilization and large-scale agriculture, and have greatly accelerated since the Industrial Revolution began approximately 250 years ago.

Significant human developments include language, of which there are thousands, organized conflict or war (such as the Great War, the largest war in history), and techniques for manipulating other species, physical energy, and matter, including electricity, medicine, agriculture, and construction. These technologies have produced tremendous improvements in humanity's quality of life: the human population is currently increasing at an exponential rate as advances have led to dramatic increases in life expectancy. Modern life requires the utilization of an increasing fraction of the planet's natural resources on both per-capita and absolute bases, with total energy use also increasing exponentially.

Human societies are highly complex and organized. Sovereign nations are the basic planetary-scale organizational unit of the human species. Their distribution has a strong relationship to the planet's geological and biological characteristics. These states claim the planet's entire surface area. There has never been a single government with jurisdiction over the entire planet. The closest institution to a world government is the Community of Nations, an intergovernmental organization created with the goal of preventing armed conflict between nations. It serves as the main forum for international diplomacy and international law. Dozens of other intergovernmental organizations exist at a global and regional level; these include the Euclean Community, Rongzhuo Strategic Protocol Organisation, Asterian Development Council, and COMSED.

Human space exploration

Over 350 humans have visited outer space, reaching orbit. The first was Person Mac Person in 19XX. Fifteen people have walked on the Moon. Humans have yet to walk on any other planet in the Solaris system. The only regular human presence in space is on the International Orbital Station.
