Xathorron:

  • Orbital Distance:  5.35 AU
  • Orbital Period:  9.5 Earth-years
  • Keplerian Ratio:  1.697
  • Radius:  3,537 km
  • Day Length:  64.9 Earth-hours
  • Atmospheric Pressure:  0.37 atm
  • Surface Temp:  388 °C
  • Surface Gravity:  0.39 g
  • Mass:  0.119 Earth-masses
  • Satellites:  >1

Xathorron is a small rock planet, with a thin atmosphere of carbon dioxide and hydrogen sulfide. The surface is scorching hot, and mainly composed of sulfur with deposits of boron.

Additional Information
The planet’s moons are an uncommon source of rhodamine. The dye can be found in mineral deposits.

Syided:

  • Orbital Distance:  0.6 AU
  • Orbital Period:  0.4 Earth-years
  • Keplerian Ratio:  1.35
  • Radius:  7,702 km
  • Day Length:  67.0 Earth-hours
  • Atmospheric Pressure:  1.18 atm
  • Surface Temp:  523 °C
  • Surface Gravity:  1.3 g
  • Mass:  1.882 Earth-masses

The proximity of the energetic star Hercules causes constant blue and violet auroras in Syided’s nitrogen-argon atmosphere. During periods of increased solar flares, the auroras are bright enough to read by on the surface, and can be seen with off-the-shelf optics from a distance of several AU.

Syided’s scorching hot surface is mainly composed of magnesium with deposits of iron. A surprising variety of simple carbon-based life flourishes in a complex network of cave systems that wind through the crust, protected from Hercules’ heat and radiation.

Survey Text
“While scanning Syided, you discovered a large debris field in geosynchronous orbit. Chief Engineer Adams conducted several detailed sweeps of the area and detected a few items of interest, including a League of One medallion encased in lead molding.”

Eletania:

  • Orbital Distance:  12.6 AU
  • Orbital Period:  34.4 Earth-years
  • Keplerian Ratio:  1.69
  • Radius:  8,864 km
  • Day Length:  35.6 Earth-hours
  • Atmospheric Pressure:  2.1 atm
  • Surface Temp:  13 °C
  • Surface Gravity:  1.2 g
  • Mass:  2.301 Earth-masses
  • Satellites:  1

WARNING: Level 1 Toxic Hazard

Eletania appears to be a world eminently suited for colonization. Sadly, appearances are deceiving. It is covered by a verdant carpet of mosses, algae, and lichen, and possesses a thick oxygenated atmosphere, but the animal kingdom is a web of microscopic symbiotic creatures. These are impossible to filter from the air and necessary for the native life to thrive. Unfortunately, they also cause anaphylactic shock when inhaled by non-native life.

In short, settlement requires either fully sealed environment suits, or replacement of the entire world’s ecosystem. Some have proposed limited colonization at altitudes above the symbiotes’ range, or in areas where favorable winds keep the air clear.

Zatorus:

  • Orbital Distance:  27.85 AU
  • Orbital Period:  113.1 Earth-years
  • Keplerian Ratio:  1.689
  • Radius:  52,290 km
  • Day Length:  17.2 Earth-hours
  • Atmospheric Pressure:  N/A atm
  • Surface Temp:  N/A °C
  • Surface Gravity:  N/A g
  • Mass:  N/A Earth-masses
  • Satellites:  >1

Zatorus is a hydrogen-helium gas giant, with high-level decks of sulphur clouds. A layer of hydrocarbons has formed deeper in the atmosphere. Vast electrical storm fronts can be seen flickering across the dark side.
