$\large\bf{\underline{\red{Light\:year}}}$

A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers). On the scale of the universe, measuring distances in miles or kilometers doesn't cut it.
