Sacaya System

Sacaya (Star)

  • System Name: Sacaya (pronounced Suh-KI-Yuh)
  • Star Name(s) and Type(s): Sacaya (Class M Red Main Sequence Star - 2.4 solar masses)

Sacaya is an old system home to a single red giant star. Most of the planets were probably burnt up by stellar expansion during the star's transitional period. The system is off-plane from the main disk of the galaxy by 18 degrees, leaving it far from nearly anything of note. The system was surveyed hundreds of years ago; the survey team found one tiny, icy dwarf that used to be in the outer reaches of the system and is now in a borderline habitable zone. However, the system has no resources of note and was passed by for colonization given its distance from everything it would need.

Three stable planets remain in orbit around Sacaya: a hot gas giant, a icy dwarf in a habitable zone, and a slowly-warming ice giant.

Sacaya I

  • Atmosphere: Type IV (primarily hydrogen, helium, and methane)
  • Hydrosphere: Dry (in the high atmospheric regions)
  • Gravity: N/A (no habitable zone)
  • Terrain: N/A (no habitable zone)
  • Length of Day: 6.4 Standard Hours
  • Length of Year: 7,200 Local Days
  • Sapient Species: None
  • Starports: None
  • Population: N/A
  • Planet Function: N/A
  • Government: N/A
  • Tech Level: N/A
  • Major Exports: N/A
  • Major Imports: N/A

Sacaya I is a very light gas giant, much like Saturn. It contains no obvious concentrations of useful, easily mined gases, which is the primary reason the Sacaya system was bypassed completely by the Republic survey team.

Sacaya I has four primary satellites, none of which appeared particularly interesting to the survey team. As a result, they are poorly mapped and scanned.

Sacaya I-A

Sacaya I-A is a small, horrendously-volcanic moon deep within the magnetosphere of Sacaya I. The moon has no atmosphere of note and sprays ice and rock from numerous volcanos nearly constantly.

Sacaya I-B

Sacaya I-B is a medium-size rocky moon tidally locked to Sacaya I.

Sacaya I-C

Sacaya I-C is a large rock and ice moon orbiting out just past the harshest magnetic bands of Sacaya.

Sacaya I-D

Sacaya 1-D is an ice moon in a highly elliptical orbit that nearly brushes the highest reaches of the gas giant's atmosphere. The moon orbits 74 degrees off the ecliptic.

Sacaya II

  • Type: Ice dwarf
  • Temperature: Frigid
  • Atmosphere: Thin Type III (No free oxygen; high methane, carbon dioxide, and nitrogen)
  • Hydrosphere: High (9% Landmass, 91% Water)
  • Gravity: Low (0.4 gs)
  • Terrain: Tundra
  • Length of Day: 17 Standard Days
  • Length of Year: 261 Local Days
  • Sapient Species: None
  • Starports: None
  • Population: None known
  • Planet Function: None known
  • Government: None
  • Tech Level: N/A
  • Major Exports: N/A
  • Major Imports: N/A

Sacaya II looks like a smaller, harsher version of Hoth. It is mostly covered in huge glaciers of water and hydrocarbon ice.

Some silicate life is native to Sacaya II. Examples are the colloquially-named "quartzicans" and "hexacrabs", non-sentient silicate life forms.

Sacaya II-B

Sacaya II-B is much like a smaller version of Sacaya II. The two are tidally locked together. Sacaya II-B is nearly 45% the mass of Sacaya II and appears to have much the same composition.

Sacaya III

  • Type: Ice Giant
  • Temperature: Frigid
  • Atmosphere: Type IV
  • Hydrosphere: Dry; mostly hydrocarbon ices
  • Gravity: N/A (no habitable zone)
  • Terrain: N/A (no habitable zone)
  • Length of Day: 31 Standard Days
  • Length of Year: 615 Local Days
  • Sapient Species: None
  • Starports: None
  • Population: N/A
  • Planet Function: N/A
  • Government: N/A
  • Tech Level: N/A
  • Major Exports: N/A
  • Major Imports: N/A

Slowly-warming ice giant, much like Neptune after the sun balloons up into a red giant.

Ring System

Sacaya III has a thick ice ring system of sufficient mass to have formed a rather large moon.

Sacaya III-A

Large, heavily cratered ice moon.
