Convert Earth's distance from sun to light year
Enter a value below to convert Earth's distance from sun [AU_dist] to light year [ly]. Reverse conversion: Convert light year to Earth's distance from sun.
1 AU_dist = 1.58125074098e-05 ly. To convert Earth's distance from sun to light year, multiply the value by 1.58125074098e-05; to go the other way, divide by it (1 ly = 63241.0770843 AU_dist). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Earth's Distance From Sun: Definition and Use
The Earth's distance from the Sun varies throughout the year. The average distance is defined as one astronomical unit (AU), which is about 149.6 million kilometers.
History/Origin
The measurement of the Earth-Sun distance has a long history, with early estimates made by ancient Greek astronomers. Modern measurements are highly precise.
Current Use
The Earth-Sun distance is a fundamental unit in astronomy and is used to measure distances within the solar system.
Light Year: Definition and Use
A light-year is the distance that light travels in a vacuum in one Julian year.
History/Origin
The concept of the light-year as a unit of distance in astronomy emerged in the mid-19th century. The first recorded use of the term was in a German astronomical publication in 1851.
Current Use
The light-year is used to express distances to stars and other astronomical objects on a galactic and intergalactic scale, especially in popular science and non-specialist contexts.
