There is an exact numerical answer to this question. By definition, 1 light year is exactly 9,460,730,472,580,800 meters. By definition, 1 mile is exactly 1,609.344 meters. So, 1 light year is exactly 5,878,625,373,183 and 849/1397 miles, by definition.
Even in light years, measuring distances across the universe becomes unwieldy. But measuring in something familiar, like miles, is truly humbling. From here to the edge of our vision spans a distance of approximately 276,000,000,000,000,000,000,000 miles. And itâs getting bigger every day. Bottom line: How far is a light-year? Itâs the distance a beam of light travels in one year â a distance of six trillion miles. Christopher Crockett Christopher has a Ph.D. in astronomy from the University of California, Los Angeles.
