System Data[edit]

Galat-Utt System[edit]

The primary is Galant, an orange giant star. It has a luminosity of 140 Sols, a mass of 4.2 Sols, and a diameter of 29.5 million km – the corona of the star lies at 0.1 AU, within orbital position (I). The inner system consists of (I) a small very hot gas giant orbiting close to the surface of the star, (IV) a vacuum worldlet, (V) a corrosive atmosphere inferno world, (VI) a very thin atmosphere inner world, and (VII) a thin atmosphere hospitable world – orbital positions (II) and (III) are empty. (VIII) Utt orbits within the habitable zone and is designated the mainworld. (IX) a sparse stony planetoid belt, (X) a large gas giant, and (XI) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(VIII) Utt[edit]

(VIII) Utt is designated the mainworld. It orbits Galant at a mean distance of 10.7 AU (1.6 billion km), within the habitable zone. It has an orbital period of 17 years 29 days and a rotation period of 31 hours. The axial tilt is 15 degrees. Utt has a diameter of 8,144 km, a density of 5.77 g/cm³, and a surface gravity of 0.67 G. The world is geologically active. Its atmosphere is rated as Dense, with a mean surface pressure of 1.69 bar and a composition of 79% nitrogen, 20% oxygen, and 1% argon, water vapour, carbon dioxide, neon and other trace gases. Approximately 60% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.25m. Mean surface temperature: 22°C. The atmosphere is active and strong weather systems driven by the star and the oceans drive across the globe. The climate is seasonal.

Satellite[edit]

Utt retains a single natural satellite, a cratered vacuum worldlet named Ishoy:

(VIIIa) Ishoy (UWP Y100000-0, orbiting at 12 Diameters/98,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 208 million km², Water surface area: 125 million km², Land surface area: 83 million km².

Native Lifeforms[edit]

Utt has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)[edit]

World starport[edit]

Utt has a poor quality starport.

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

World technology level[edit]

Utt possesses a Technology Level of TL–4.

World government[edit]

Utt has a Balkanized Government.

  • No central ruling authority exists. Rival governments compete for control.
  • The typical power source of this government is a Balkanization.
  • The typical power structure of this government is a Confederation (Anarchy).
