Parsec to lightyear11/25/2022 One common confusion about parsecs is that they are a unit of time instead of distance. A Common Confusion Comparing Parsec to Lightyear So, while a lightyear is more intuitive in that most people know a lightyear is the distance light can travel in one year, a parsec is more precise.įurther, the system that is used by starship navigators to determine the location of star systems throughout the galaxy is based on parsecs, not lightyears. In addition, it’s possible that Galactic days were shorter than earth equivalents. Since a year on Earth is 365 days, this would change the length of a lightyear in the Star Wars universe. The Galactic Standard Calendar in Star Wars had the length of a year at 368 days. The issue with using lightyears as standard is that the length of lightyear travel depends on how long a year is, which is not necessarily standard. In the Star Wars universe, a parsec appears to be equal to the real-world measurement. Astronomers use parsecs more often than lightyears because it makes math easier, and parsecs are more closely related to the strategies astronomers use to figure out the size of the universe. While some may think that a parsec is a purely fictional measurement because of its widespread use in Star Wars, a parsec is a unit of distance used by real-life astronomers. Using the Gregorian calendar (where a year is 365.2425 days), a lightyear is about 9.461 trillion kilometers. In terms of converting units of parsec to lightyears, one parsec is equal to 3.26 lightyears.Ī lightyear is the distance that light can travel in one year. One parsec is equal to about 30 trillion kilometers. How long is a parsec? A parsec is a unit of distance commonly used when talking about space travel in Star Wars.
