Which physical quantity is measured in light year?
Distance
A light year is defined as the distance that light travels in vacuum in one year.
Since it is obtained by multiplying the speed of light by a fixed duration of time, the resulting quantity is a length, not a speed, a time, or a measure of brightness.
Hence, the physical quantity measured in light year is distance.
