A light year measure the distance a lightbeam can travel in one year one light year is equivalent to 9500000000000 km why do scientist use light years to measure distances in the universe.
Light years are the only practical unit for measuring the distance of space
Light years tell us about the temperature distance and age of their celestial bodies
Light years are the most accurate form of measurement for universal purposes
Light years measure the age of celestial bodies by determining how bright the light is
