(SOH-luhn)
Unit of Distance | Interstellar Standard Measure
A solun is the galactic standard unit of long-range astronomical distance, equal to approximately 5 lightyears. It is used primarily for mapping stellar systems, plotting deep space travel, and measuring the reach of long-range communications or weaponry.
The term solun is derived from the words sol (meaning “star”) and lun (an archaic reference to celestial cycles), signifying the span of a single stellar circuit in standardized galactic time. The unit was first adopted by the Galactic Civil Authority (GCA) following the unification of star charts across the Galactic Commons.
Conversion:
- 1 solun = ~5 lightyears
- 1 solun ≈ 47.3 trillion kilometers
- Travel across 1 solun at standard warp velocity (Class-V ship) takes approximately 3.5 galactic days, depending on interstellar drift and gravitational interference.
