In the next few years, we might learn whether they have atmospheres or oceans, or even signs of habitability. Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. One light-year is about 6 trillion miles (9 trillion km). A light year is a measure of distance, not time, despite its name. the line by 7.5 (the corresponding distance is one light-second), then [3], The light-year is most often used when expressing distances to stars and other distances on a galactic scale, especially in non-specialist contexts and popular science publications. We use light-time to measure the vast distances of space. 93 million miles Which really puts things into perspective when considering just how wild it is that we have a spacecraft about to reach Destination Pluto.
