Yebel is a ring of many small worldlets (planetoids AKA an "asteroid belt"), not capable of retaining an atmosphere or water, and nonindustrial in nature.

  • These worldlets warrant hazardous environment precautions.
  • Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.
  • The worldlets require extensive imports of outside technology to maintain a modern, star-faring society. Having to import most manufactured and high tech goods drives the price up for these items at this world.
  • It is a Non-Aligned world dominated by human sophonts located in the Tsorva Subsector of Halcyon Sector.

System data[edit]

Kinnison System[edit]

The companion is Kinnison, an ordinary red main sequence star. Kinnison and Kindel, the companion star, orbit one another at a mean separation of 343 AU and have an orbital period around their barycenter of approximately 7600 years. Kinnison has a luminosity of 0.0334 Sols, a mass of 0.4574 Sols, and a diameter of 711,000 km. (I) a corrosive atmosphere inferno world, (II) a thin atmosphere bigworld, (III) a dense rocky planetoid belt, (IV) a large gas giant, (V) a large gas giant, (VI) a small gas giant, and (VII) a sparse icy planetoid belt form the outer system. Many of the worlds retain satellites.

Kindel-Yebel Subsystem[edit]

The primary is Kindel, a dim red main sequence star. Kindel and Kinnison, the primary star, orbit one another at a mean separation of 343 AU and have an orbital period around their barycenter of approximately 7600 years. Kindel has a luminosity of 0.0025 Sols, a mass of 0.244 Sols, and a diameter of 334,000 km. (I) a vacuum worldlet, (II) the Yebel Main Belt, designated the mainworld, (III) a small gas giant, (IV) a small ice giant, and (V) a trace atmosphere iceworld form the outer system. Both of the giant worlds retain satellites.

Mainworld Data[edit]

(II) Yebel Main Belt[edit]

(II) the Yebel Main Belt orbits within the outer zone and is designated the mainworld. It lies at a mean distance of 0.41 AU from Kindel and is primarily made up of carbonaceous bodies with diameters of less than 100 km. The inner edge of the belt, with a higher concentration of nickel-iron bodies, is considered to lie at around 0.26 AU from the star and the the outer edge of the belt, with a higher concentration of icy bodies, is considered to lie at approximately 0.56 AU. The main inhabited body is a cratered oval rock named Fenian's Stone, with a mean orbital distance of 0.33 AU around Kindel and an orbital period of 140 days 4 hours. It has a long axis of 270 km, a density of 3.32 g/cm³, and a surface gravity of 0.013 G. It retains no atmosphere and has no hydrographics. Mean surface temperature: -172°C in sunlight, -220°C in shadow.

Native lifeforms[edit]

No world in the Yebel system is known to have native life.

History & Background (Dossier)[edit]

World starport[edit]

Yebel has a routine quality starport.

  • A Class C Starport Facility has minimal if any shipyards and can only perform extremely limited repair work.
  • This facility has many very skilled personnel who can perform surprisingly sophisticated repair work despite the limited facilities.
  • This facility has refueling infrastructure and limited refining capabilities. One may purchase unrefined fuel here.
  • Starports of this class rarely have both a Lowport and a Highport.

World technology level[edit]

Yebel possesses a Technology Level of TL–10 or TL-A in Hexadecimal Notation.

World government[edit]

Yebel has a Feudal Technocracy government.

  • It is a government by specific individuals for those who agree to be ruled. Relationships are based on the performance of technical activities which are mutually-beneficial.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Hegemony.
