Notes (2007)[edit]

Traveller star-maps all use hexes which are one parsec wide. The parsec also determines the range of the Jump Drive.

  • The original authors used Parsecs as a measurement for their maps over the more used (hence less sexy) light-years.
  • Many measures, such as this one are highly dependent on Earth's configuration. Eg. a circle is divided into 360 degrees because that was the number of days in a year in the Persian calender and/or has many factors. Division into arcminutes and arcseconds, each 1/60 of the degree is also highly dependent on the Earth time system, dividing an hour by 60s (note that 24 is also a factor of 360). Other races could use other circle divisions, 2520 has better factoring, pi, or radians. Even the light year only makes sense in a Terran context, as it is dependent on the time it takes earth to circle Sol.
  • For example Vland has an orbit of 1.276 AU and a day of 22.93 hours. Given the same division of a circle into degrees/minutes/seconds a Vilani Parsec would be 1.276 times larger, eg. 4.162 instead of 3.262 light-years. (Of course with a year of 478.72 days, this would be 3.175 Vilani Light-years). Then again, Vilani may have 480 degrees in their circle giving a Vilani Parsec a completely different value.

In fact there is a Deshi, the Vilani parsec, but no indication of how it is derived.
