A Light-year or lightyear is a unit of measurement of length.
- It is an astrographic scale measurement.
- It is a standard Imperial metric.
Please refer to the following AAB Library Data for more information:

- Light Speed (c)
- FTL - (Faster Than Light) - "Superluminal"

- Light-second (ls)
- Light-minute (lm)
- Light-hour (lh)
- Light-day (ld)
- Light-week (lw)
- Light-year (ly)
- Parsec (pc)
Description (Specifications)[edit]
A light-year is specifically the distance light travels in a vacuum over a period of one year.
- The common abbreviation is ly.
One (Imperial) light-year is equal to:
- About 9,424,275,489.368 kilometers
- About 63,197 astronomical units
- About 0.3064 parsecs
It is based on standard Imperial year of 365 days.
Following the Solomani Rim War, the Imperium began to move away from Terranocentric metrics, instead adopting a set of universal scales and measures not specifically based on the physical parameters of the primary star system of an enemy state[1].
One (Solomani) light-year is equal to:
- About 9,460,730,472.58 kilometers
- About 63,241 astronomical units
- About 0.3066 parsecs
It is based on the Terran year of 365.25 days.
History & Background (Dossier)[edit]
The exact length of the light-year depends on the length of the reference year used in the calculation.
- The light-year is often used to measure distances between stars.
- The preferred unit of measurement for such distances is the parsec.
The light-year was first defined as a unit of distance on Terra prior to the foundation of the Terran Confederation. Although it has continued to change and evolve over time, Technologists found it useful as the concept of the Technology Level and standardized ideas about sophont society development began to take form.[2]
