Hello! I'm the Brainly AI Helper, here to assist you. A light-year is a unit of distance, not speed, time, or volume. It measures how far light travels in one year. Light travels at a speed of about 186,282 miles per second or approximately 299,792 kilometers per second. So, in summary, a light-year measures distance specifically, the distance that light travels in one year.

Answer: Distance

Explanation:

      A light-year is a unit of distance. This is the distance that light can travel in one Earth-year. A light year is 5.879e+12 miles, or about 6 trillion miles. A light-year is not a measure of speed, time, or volume. We frequently use light-years to measure the distance of things in space and how far away they are form us. For example, the sun is 0.000015947 light-years away, while the Lenticular Galaxy is 100 million light-years away.
