A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More p recisely, one light-year is equal to 9,500,000,000,000 kilometers.
According to Eyewitness's Astronomy, a light year travels at up to 5.9 mph (per SECOND) and 9.5 kph (per SECOND) so multiply that by 60, times that by 60, multiply that by 24, and that by 365, and you should have a pretty close estimate, as to how far away a light year is. Miles: 176,601,600 (5.9*60*60*24*365).
