Light year
From Wookieepedia, the Star Wars wiki.
A light year, also light-year, abbreviated ly, is the distance light travels in one year.
Since the Galactic Standard Calendar used a year of 368 days, the length of a Galactic Standard Light Year would have been 9,531,961,160,601,600 meters.
[edit] Behind the scenes
This assumes that the the "Galactic Standard" Day, Hour, etc. and Meter are equal to Earth's. The Galactic light year was 0.75% longer than an Earth based light year.
It is also possible that Galactic days (and hours etc.) were 0.75% shorter than there Earth equivalents, and that the light years are the same length. (see below)
The exact length of a light year depends on the exact length used for one “year”. On Earth The IAU uses a Julian year of 365.25 days, while other sources may use a Gregorian year of 365.2425 days, or another year altogether.
| Source | year (days) | light year (kilometer) | light year (miles) |
|---|---|---|---|
| IAU | 365.25 | 9,460,730,472,580,800 | 5,878,625,373,184 |
| Gregorian | 365.2425 | 9,460,536,207,068,020 | 5,878,504,662,190 |
| 365.242199 | 9.460 528 4 ×1015 | 5.878 499 81 ×1012 | |
| Yahoo | 365.2411‡ | 9.460 5 ×1015 | 5,878,482,164,161 |
| Coruscant | 368 | 9,531,961,160,601,600 | 5,922,886,070,723 |
‡ Note that while Yahoo separately reports a year length of 365.24220 days, its rounding of the light year length to five digits, works out to a year length of ~365.2411 days.
