What is a light year?

A light year is the distance light travels in vacuum during one Julian year, approximately 9.4607 × 10^15 meters, used to express astronomical distances.

What does exameter represent?

An exameter is an SI unit equal to 10^18 meters, utilized for expressing very large distances in astrophysics and cosmology.

Why convert light years to exameters?

Converting to exameters helps standardize astronomical distances into SI units, aiding easier comparison and communication of large-scale measurements.
