WebA light year is the distance traveled by light in one year. How far is it? Multiply the number of seconds in a year by the number of miles or kilometers that light travels in a second, and there you have it: a light year. This is approximately 5.88 trillion miles (9.5 trillion km). Web7 apr. 2024 · By Nadia Whitehead.
