Arpester is a barren vacuum world with no overt population, government, or law level.

• 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.
• This world could be populated if anyone had an inclination to do so...
• It is an unclaimed Non-Aligned world located in the Ingo Subsector of Astron Sector.

• Vacuum worlds have no climate, but experience extreme differences in temperature between direct starlight and shade.

• The mainworld, orbiting in the outer system.
• x11 secondary rocky worlds. Two temperate worlds orbit within the habitable zone.
• x3 gas giants.

Mainworld Data

The mainworld orbits within the outer system.

• It receives very low levels of stellar energy.

• The world orbits beyond the star's Jump Shadow.

Mainworld Size (S)

Arpester is a Small World between 900km and 2,400km in diameter. The world has very low gravity between 0.05G and 0.09G. The horizon will appear about 2km away.

Arpester has no free-standing water or ice on the surface. Wilderness refueling isn't possible on this world. Water for the inhabitants needs to be imported and extensively recycled. These worlds are classified Desert World or a Hell World depending on their atmosphere.

Satellites

Arpester retains a tiny spherical vacuum moon.

• The world orbits once every few weeks.

Mainworld Geography and Topography

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