Overview

Aurorium is a volcanically active inner-system planet orbiting close to Pol Star. Characterized by extreme surface temperatures, constant tectonic instability, and a highly toxic atmosphere, the planet is naturally hostile to biological life. These conditions have made Aurorium unsuitable for civilian habitation but strategically valuable for controlled, high-security purposes.

From a Denebolian administrative standpoint, Aurorium functions as an international prison world, hosting detention facilities for individuals classified as high-risk by Accord authorities. Its environmental lethality provides a natural containment layer that significantly reduces escape feasibility and operational overhead. 

Key info

Orbit: 2nd

Orbital period: 0,5 Py

Mass: 0,7 Pmass

Gravity: ~ 0,9 PG

Avg surface temp.: ~ 480 C

Atmosphere: Toxic, Dense CO2 with sulfuric aerosols

Habitability: Non-habitable

Administrative control: Denebolian Accord

Overview

Its atmosphere is dominated by carbon dioxide and sulfuric compounds, producing extreme greenhouse conditions and surface pressures approaching ninety times that of Panthalassa. Average surface temperatures remain near 480 °C, making the planet lethal to all known forms of life and machinery not specifically hardened for extreme environments.

Caelum's hostility is atmospheric rather than geological. Severe turbulence within its cloud layers prevents the construction of stable orbital or atmospheric habitats, and surface operations are limited to short-duration automated probes.

Key info

Orbit: 3rd

Orbital period: 0,7 Py

Mass: 0,8 Pmass

Gravity: ~ 0,9 PG

Avg surface temp.: ~ -100 C

Atmosphere: Dense N2-CH4 with CO2 traces

Habitability: Non-habitable (theoretical subsurface potential)

Administrative control: Denebolian Accord

Moons: (1) Nalu

Overview

The planet is characterized by a dense atmosphere and a highly reflective surface composed primarily of ice-covered global oceans. Due to its high albedo Aquiluna retains little solar heat, resulting in an average surface temperature of approximately –100 °C.

Geological and magnetic data strongly suggest the presence of liquid water beneath its ice crust, maintained by internal heat and tidal interactions with its moon, Nalu. While no direct evidence of life has been observed, Aquiluna is considered one of the most promising candidates in the Pol Star System for theoretical subsurface biospheres, and remains under continuous long-term observation by Denebolian research institutions.

Key info

Orbit: 4th

Orbital period: 1 Py

Mass: 1 Pmass

Gravity: ~ 1 PG

Avg surface temp.: ~ 18 C

Atmosphere: N2-O2 dominant, breathable

Habitability: Fully habitable

Administrative control: Capital world of Denebolian Accord Alliance

Moons: (2) Thalor, Lone

Overview

With a stable climate, breathable atmosphere, and extensive hydrosphere, the planet supports a large and technologically advanced population distributed across continental landmasses, archipelagos, and artificial oceanic structures. Its average surface temperature of approximately 18 °C allows for long-term ecological stability and agricultural sustainability.

Panthal hosts the Accord's primary governing institutions, major interplanetary trade hubs, and command-level STARS infrastructure. The presence of two moons, Thalor and Ione, generates strong but predictable tidal forces that influence both oceanic circulation and planetary climate. Panthal's orbital space is densely developed, reflecting its role as the central node of civilization within the Pol Star System.

Moons: (4) Eryth, Kalyx, Myra, Solen

Overview

Gaistra is the largest planetary body in the Pol Star System and occupies the fifth orbit around Pol Star. It is a massive gas giant characterized by bright cloud bands, intense auroral activity, and a powerful magnetosphere. Although uninhabitable, Gaistra plays a major visual and gravitational role within the system and is the fourth brightest object visible from Panthalassa's surface.

Several of Gaistra's moons exhibit conditions that warrant long-term study, including subsurface oceans and geothermal activity. In addition, the planet is encircled by a dense asteroid ring composed of rocky and metallic debris, believed to be the remnants of a failed moon formation event. These features make Gaistra a priority target for future scientific and industrial expansion.

Key info

Orbit: 6th

Orbital period: 136 Py

Mass: 125 Pmass

Gravity: ~ 1,8 PG (upper atmosphere)

Avg surface temp.: ~ -160 C

Atmosphere: H2, rich with sulfur and rare exotic gases

Habitability: Non-habitable

Administrative control: Denebolian Accord

Moons: (7) Rhex, Vael, Tyr, Ophra, Nym, Caer, Loth

Overview

Exlipta is an outer-system gas giant defined by extreme atmospheric instability and persistent planet-scale storm systems. Its atmosphere contains significant concentrations of rare gases and exotic compounds of high theoretical industrial value. However, the planet's violent weather patterns, electromagnetic interference, and unpredictable pressure gradients have rendered all extraction attempts unsuccessful.

Exlipta is surrounded by a chaotic asteroid ring composed of captured debris and fragmented moonlets. Combined with its seven unstable moons, this environment makes the planet one of the most hostile locations in the Pol Star System. As a result, Exlipta remains classified as a high-risk observation and research target rather than an active industrial asset.

Key info

Orbit: 7th

Orbital period: 155 Py

Mass: 0,6 Pmass

Gravity: ~ 0,8 PG

Avg surface temp.: ~ -60 C

Atmosphere: Thin CO2-N2 mix

Habitability: Non-habitable (artificial only)

Administrative control: Denebolian Accord

Moons: (1) Astrae

Overview

Luminae is a cold, dimly lit rocky planet located at the outer edge of the Pol Star System. Due to its distance from Pol Star and thin atmosphere, the planet exists in a state of near-perpetual twilight, with surface temperatures averaging around –60 °C. Natural habitability is impossible without artificial support.

Luminae hosts a restricted SHIELD research outpost, dedicated to high-risk scientific projects that cannot be conducted safely elsewhere in the system. Its fragmented asteroid ring provides both a navigational hazard and a natural layer of signal interference, which is actively exploited for operational concealment.

Key info

Orbit: Highly eccentric, inclined

Orbital period: 149 Py

Mass: 0,09 Pmass

Gravity: ~ 0,3 PG

Avg surface temp.: ~ -90 C

Atmosphere: None

Overview

Small rocky planetoid with a highly inclined and eccentric orbit that periodically carries it across the orbital planes of multiple planets. For part of its orbit, Atrière becomes the most distant known object in the Pol Star System. Its surface is heavily cratered, with traces of ancient cryovolcanic activity and localized radiation anomalies.

Due to its unstable orbit and lack of immediate strategic value, Atrière remains under passive observation only. However, unexplained geometric surface features detected by orbital surveys have ensured continued scientific interest and classification as a protected body under Denebolian Accord regulations.

Overview

Long-period comet following a highly eccentric and inclined orbit that carries it through the inner and outer regions of the Pol Star System. Its trajectory intersects the orbital zones of multiple planets, including Aquiluna, Panthalassa, and Gaistra, before extending far beyond the orbit of Luminae. The comet's orbital inclination places it well outside the primary planetary plane.

During perihelion passage, when the comet approaches Pol Star, Matrichal Comet develops a pronounced dual tail composed of ionized gases and fine particulate dust. These events are visible from Panthalassa and have been recorded continuously since the early observation era. Spectroscopic analysis suggests the comet contains complex organic compounds alongside volatile ices, making it a valuable reference object for studying early system formation and primordial material retention.
