What unit of measurement represents the distance light travels in one Earth year?

Explanation:

A light-year is a unit of distance, not time, representing the distance light travels in a vacuum in one Julian year. It is approximately 9.46 trillion kilometers (5.88 trillion miles) and is used to measure the vast distances between celestial objects like stars and galaxies. An Astronomical Unit (AU) is used for distances within our solar system, and a Parsec is a larger unit often used by professional astronomers.
