A light year is a unit of distance, not time. It is the distance that light travels in one year, which is approximately 5.88 trillion miles or 9.46 trillion kilometers. This vast distance is used to measure the scale of the universe and is often used in astronomy to describe the distances between stars and galaxies. **
