A light-year is a unit of distance that represents how far light travels in one year in the vacuum of space. Since light moves at a speed of about 299,792 kilometers per second (or approximately 186,282 miles per second), a light-year is equivalent to about 9.46 trillion kilometers (or about 5.88 trillion miles).
