Akkadia System



System Notes

  • From plane of planets they form an eclipsing binary
  • Due to Roche lobe instability they sometimes form and exchange semi-attached
  • Distance apart from the A and 9 B - 0.3 AU
  • Seven primary planets
  • The Akkadian system lies at the edge of Minor arm of the Milky Way, known as the Sagittarius arm just where it intersects with the Orion-Cynus arm
  • In Star Trek canon it would lie near the intersection of Romulan, Klingon and Federation space

Name: Akkadia II (Akkadia)
Type: Class O - Palegic
Axial Tilt: 36 degrees
Eccentricity: 0.008
Orbital Period: 1.5 years
Satellites/Rings: None - A set of spectacular multicolored rings. No moons (tidal forces broke them up long ago to form rings)

Equatorial radius: 6500 km
Polar radius: 6458
Flattening: 0.0065
Surface Area: 519828786 km

  • Land: ~18% - 93569181 km

Synodic Period: 1.5 years
Axial Tilt: 36 degrees
Sidereal Rotation: 18 hours
Surface Temperature: ~19 C
Gravity: 0.85 G
Albedo: 0.38

Atmosphere

  • Surface Pressure: 101.3 kPa (MSL)
  • Composition: 75% Nitrogen (N2), 4% Oxygen (O2), 0.93% Argon, 0.038% CO2, ~3% water vapor
Other Data
  • No polar ice except in extreme times
  • Habitats = less diverse than Earth's, on land due to the small amount of land.
    - The largest habitats on land are either tropical forest and temperate forest, mixed savanna (scattered trees, groves, or riverine strips in dry grassland), veldt, alpine vegetation, there is very little desert.
  • Shallow seas have large coral reefs leading to a rich diversity
    -Salinity 2%
  • Biomass approximately 133% Sols, most in the sea due to rich diversity of the coral reefs and lush forests.
  • Climate belts = The denser air and fast spin creates four convection circulation cells.
    - These four convection cells create a torrid zone at the equator, a warm dry zone around 18 degrees north and south, a temperate wet zone around 36, a cool dry zone near 54, a cold wet zone around 72.
  • Due to orbit along the solar plane and the rotation of the twin suns creating an eclipsing binary result in an eight season calendar
  • Relief above water = mostly low, but with startling exceptions.
  • The highest peak is over 5 km above sea level (20,000'). Greatest depth is approximately 4km
  • The sea is always near, and most climates are maritime
  • Tropical or temperate lands; very little beyond 60 north or south
  • Narrow, tall, straight coastal ranges
  • Plains dotted with deep lakes
  • Cloud cover = Denser. All that extra surface water for the sun to evaporate moisture from.
  • Inhabited with a sentient indigenous race
