Overview
Qutroinus is a mid-sized terrestrial planet located within the outer fringes of the Milky Way Galaxy, and under the control of the Confederacy of Humanity. With a diverse biosphere and unique orbital features, Qutroinus serves as both a scientific curiosity and a key strategic point for Confederacy operations. The planet is renowned for its wide range of lifeforms, both terrestrial and marine, which have adapted to its lower-than-Earth atmospheric pressure and gravity. The presence of life on its moons, albeit sparse, has also led to increased interest from xenobiologists and terraforming engineers alike.
Moons
Qutroinus boasts a total of six moons, five of which are small asteroid-like satellites, while the sixth is a captured rogue planetesimal. Despite their diminutive sizes, all the moons maintain temperatures conducive to life, a phenomenon that defies standard astrobiological expectations. The rogue moon, named Veirth, has shown signs of primitive microbial life beneath its icy surface, while the remaining moons, dubbed Q-1 through Q-5, are barren rocks with occasional bursts of geothermal activity. The exact mechanisms that allow for such stable temperatures remain under study, with hypotheses ranging from deep-seated geothermal heating to unknown energy sources beneath their crusts.
Physical Characteristics
With a diameter of 9,342.07 miles (15,036.34 kilometers) and a surface gravity of 0.89833 g, Qutroinus is slightly smaller and less dense than Earth. Its atmosphere is notably thinner, with a pressure of 0.3 atm, necessitating supplemental breathing gear for human visitors. Despite this, native life has thrived, evolving specialized adaptations to the lower oxygen content and varying atmospheric composition. The planet's surface is dominated by vast oceans and sprawling archipelagos, interspersed with volcanic mountain ranges and deep, forested valleys. Several research stations have been established along its equatorial regions to study the interplay between marine and terrestrial ecosystems.
