A light-year is a unit of distance used mostly to measure enormous gaps between celestial bodies. The light-year measures how far light travels in a vacuum over a span of one Julian year (365.25 days). Since light travels at an astonishing speed of 300,000 km/s, one light-year converts to approximately 9.46 trillion km or 5.88 trillion miles.
