Athune is a high-population, industrial world with a billion or more sophonts in population size.

  • As an industrial world, this planet has well-developed manufacturing and processing industries. Manufactured goods are a major export item.
  • Its economy is rapidly growing and living conditions are expected to rapidly improve barring outside forces.
  • It is a part of the Yimin Jiti in the Veesene Subsector of Halcyon Sector, which is part of the Distant Fringe.
  • This world-system hosts a Military Base, usually associated with military ground forces, which may be located on or off-world.

System Data[edit]

Barka-Athune Subsystem[edit]

The primary is Barka, an ordinary yellow main sequence star. It has a luminosity of 1.21 Sols, a mass of 1.04 Sols, and a diameter of 1.433 million km. The inner system consists of (I) a trace atmosphere worldlet, (II) a corrosive atmosphere inferno world, and (III) a dense atmosphere stormworld. (IV) Athune orbits within the habitable zone and is designated the mainworld. Orbital positions (V) through (VIII) are unavailable due the presence of the companion star. (IX) a sparse stony planetoid belt, (X) a large gas giant, and (XI) a small gas giant form the outer system. Many of the worlds retain satellites.

Yast Subsystem[edit]

The companion is Yast, a dim red main sequence star that orbits Barka at a mean distance of 5.74 AU (orbital position (VII), 858.7 million km), and with an orbital period of 13 years 177 days. It has a luminosity of 0.001 Sols, a mass of 0.215 Sols, and a diameter of 280,000 km. (I) a trace atmosphere iceworld, and (II) a small ice giant form the outer system. The ice giant retains satellites.

Mainworld Data[edit]

(IV) Athune[edit]

(IV) Athune is designated the mainworld. It orbits Barka at a mean distance of 1.11 AU (166 million km), within the habitable zone. It has an orbital period of 418 days 20 hours and a rotation period of 22.5 hours. The axial tilt is 16 degrees. Athune has a diameter of 12,783 km, a density of 5.62 g/cm³, and a surface gravity of 1.02 G. The world is geologically active. Its atmosphere is rated as Dense, Tainted, with a mean surface pressure of 1.91 bar and a composition of 82% nitrogen, 17% oxygen, and 1% argon, water vapour, carbon dioxide, neon and other trace gases. The atmospheric taint is caused by the relatively low percentage of atmospheric oxygen abd allergenic spores and pollens of organic origin. Approximately 83% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.5m. Mean surface temperature: 8°C. The atmosphere is dynamic and powerful weather systems driven by the star sweep across the globe. The climate is seasonal.

Satellite[edit]

Athune retains a single natural satellite, a thin atmosphere hospitable world named Lessian:

(IVa) Lessian (UWP G446315-8, orbiting at 40 Diameters/511,000 km)

Mainworld geography and topography[edit]

Total surface area: 513 million km², Water surface area: 426 million km², Land surface area: 87 million km².

Native lifeforms[edit]

Both Athune and Lessian have extensive native life. Their metabolic functions drive the processes of atmospheric renewal.

World starport[edit]

Athune has a good quality starport.

  • A Class-B Starport Facility has not very well developed shipyards and is only capable of producing spaceships.
  • This facility has many very skilled personnel who can perform not only major repair work, but overhaul work as well.
  • This facility has advanced refueling and refining infrastructure. One may purchase practically any kind of refined fuel here.
  • Almost every starport of this class possesses both a Lowport and a Highport. Such ports rarely have more than one of each kind of port.

World technology level[edit]

Athune possesses a Technology Level of TL–9.

  • Common Communication technologies for this TL include: Fiber optics and satellite communication and data networks.
  • Common Power Generation technologies for this TL include: Early fusion power.
  • Common Transportation technologies for this TL include:
    • Land: Ultra high-speed trains and early grav vehicles.
    • Water: High efficiency sailcraft, multihulled seacraft, improved artificial gears.
    • Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
    • Space: SSTO spacecraft, early military spacecraft, and interstellar STL starships
    • FTL: Prototype Jump Drive-1.

World government[edit]

Athune has an Impersonal Bureaucracy government.

  • It is a government by agencies which are insulated from the governed.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Hegemony.
