A light year, also light-year, abbreviated ly, is the distance light travels in one year. 3.26 light years make up a parsec, which was a unit of distance that was important in locating star systems in the known galaxy.
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.
Behind the scenesEdit
The above calculation assumes that the Galactic Standard Day, Hour, etc. and Metre are equal to Earth's, and results in a Galactic light year 0.75% longer than an Earth-based light year.
It is also possible that Galactic days (and hours etc.) were 0.75% shorter than their Earth equivalents, and that the light years are the same length. (see below)
The length of a light year depends on the exact length of one year. On Earth, the International Astronomical Union (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 (meter)||light year (miles)|
|365.242199||9.460 528 4 ×1015||5.878 499 81 ×1012|
|Yahoo||365.2411‡||9.460 5 ×1015||5,878,482,164,161|
‡ Note that while Yahoo separately reports a year length of 365.24220 days, its rounding of the light year length to five digits results in a year length of ~365.2411 days.
