Elvus is a binary star system.

• The primary is a red main sequence.
• The secondary is a brown dwarf substellar object.

System Data

The worlds of the system have been surveyed. They consist of:

• The mainworld.
• x10 secondary rocky worlds.
• x3 planetoid belts.

Mainworld Data

Elvus is a Twilight Zone World.

• One side of the world permanently faces towards the star and one side permanently faces away.
• In the narrow region between permanent night and permanent day, the primary star eternally hangs on the horizon.

The mainworld orbits within the star's Habitable Zone.

• It lies within the zones colder outer H- region.
• It receives lower levels of stellar energy.

• The world orbits inside the stars Jump Shadow.

Mainworld Size (S)

Elvus is a Big World between 20,000km and 21,600km diameter. The world has a high gravity between 2.0 and 2.1G. The horizon will appear about 6.6km away. Vessels with 2G of thrust or less should not land on this world. Vessels with 3G of thrust should check with local starport authorities before attempting to land using emergency power.

Mainworld Atmosphere (A)

Elvus has an Insidious Atmosphere which requires the use of a Hostile Environment Suit or Vacc Suit, but extreme conditions cause the corrosive effects to defeat any personal protective measures in a few hours. TL–10 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Elvus has 05-15% of its surface covered by a fluid other than water. Wilderness refueling is not possible. Water for the inhabitants needs to be imported and extensively recycled. These worlds may be Hell Worlds.

• This surface fluid may be ammonia, methane, hydrocarbons, or other exotic liquids depending on the local temperature and environment.
• The world has an arid, hostile surface environment.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

• Locally, detailed maps may be available.
• Verified updated charts are constantly sought.
• Detailed survey data commands premium prices.

Native Lifeforms

Primitive exotic native life occupying a few niche habitats. Its metabolic functions help regulate the process of atmospheric renewal.
