What unit of measurement represents the distance light travels in one single year?
Answer
Light-year
A light-year is the standard unit of measurement used by scientists to describe the vast distances between stars because traditional measurements like miles or kilometers are impractical in space. Since light travels at an incredible speed of approximately 186,000 miles per second, a light-year represents the colossal distance—about 6 trillion miles—that light covers over the course of one year. This unit helps quantify the immense scale of the universe and explains why distant stars appear as tiny pinpricks in the sky.
