A Light-year or lightyear (symbol: ly) is a unit of measurement of length, specifically the distance light travels in vacuum in one year.
- It is an astrographic metric.
Description (Specifications)
One light-year (Solomani) is equal to:
- about 9,460,730,472,580 meters
- about 63,240 astronomical units
- about 0.3066 parsecs
One light-year (Imperial) is equal to:
- about 9,454,449,092,018 meters
- about 63,200 astronomical units
- about 0.3064 parsecs
History & Background (Dossier)
The exact length of the light-year depends on the length of the reference year used in the calculation.
- Within the Imperium, an Imperial standard year of 365.00 Imperial standard days is used.
- The light-year is often used to measure distances between stars.
- The preferred unit of measurement for such distances is the parsec.
