An Astronomical Unit is a unit of measurement of distance, frequently used to measure inter-planetary distances.


Please refer to the following AAB Library Data for more information:

  • NAFAL (STL) - (Not As Fast As Light) / (Slower Than Light)
  • Light Speed (c)
  • FTL - (Faster Than Light) - "Superluminal"
» Imperial Standard Astronomical Unit
» Solomani Parsec
» Vilani Parsec ("Deshi")
» Imperial Standard Parsec



Description (Specifications)

One Astronomical Unit is about 150 million kilometers (or, more precisely, 149¨597 870 691 ± 30 meters), or about 93 million miles.

  • The standard abbreviation is AU.
  • One Astronomical Unit is approximately equal to 500 light-seconds.

History & Background (Dossier)

Because the definition of a Parsec originally relied upon the Astronomical Unit, the AU has become a standard unit of measurement within the Imperium.

Imperial vs. Solomani Astronomical Unit Usage

The Solomani define the Astronomical Unit as the distance between Terra and Sol, the system's primary star, yielding a value of almost precisely 499 lightseconds.

Modern Imperial usage bases the AU on the distance between Capital and its sun, which happens to have an almost identical orbital distance to that of Terra around Sol. This definition of the AU was broadly adopted following the Solomani Rim War, in order to avoid the use of specifically Terracentric metrics.[1]
