Teleon, commonly referred to as Earth or the World, is a terrestrial planet orbiting the Sun. It is the fifth-largest and fifth-most-massive object in the Solar System, as well as the only currently known celestial object in the Solar System and the known universe to harbor and sustain life. Additionally, it is the largest and densest of the Solar System's rocky planets. Teleon 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.

Teleon 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 Teleon.

Various factors such as the aforementioned and particularly Teleon'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 Teleon's history, spawning a plethora of biodiversity and occassionally punctuated by mass extinction events. Today, the modern human (homo sapiens) inhabits Teleon 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.

Inner Solar System

The inner Solar 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 SOlar 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 Solar 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 Teleon 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).

Teleon

Teleon, 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, Teleon 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. Teleon 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 Solar System.

Luna

Luna, or the Moon, is the only natural satellite of Teleon. With approximately two-thirds the diameter and one quarter the mass of Teleon (0.27 M_🜨), Luna, as a planetary-mass object, is considered to be the binary planetary partner to Teleon, and its gravitational influence so large that the barycenter of the Teleon system lies outside Teleon, causes Teleon's tides and is responsible for its tidal acceleration, as is vice versa the case for Luna due to Teleon'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 Teleon and Luna in a circumplanetary disk.
