Understand Astronomical Unit and Light Year Units

An Astronomical Unit (AU) is a unit of length, roughly the average distance between Earth and the Sun. It’s primarily used for measuring distances within our solar system.

A Light-Year, on the other hand, is the distance that light travels in one year. Because the universe is so vast, light-years are used to measure distances to stars and galaxies far beyond our solar system. One light-year is equivalent to approximately 63,241 AU.

How to Convert Astronomical Unit to Light Year

  1. First, find the conversion factor. 1 light year is equal to 63,241 astronomical units (AU).
  2. Then, divide the number of astronomical units by the conversion factor (63,241) to get the equivalent in light years.

For example, if a star is 126,482 AU away, then it is 126,482 / 63,241 = 2 light years away.
