One light-year is the distance traveled by light in 1 year. Light travels at 186411.4 miles per second, and there are 113529600000 seconds in one year, so 1 light-year is:
1 ly = (186411.4 mi/s)(113529600000)
1 ly = 5,874,589,924,204 miles
Note that our nearest star, Alpha Centauri, is about 4 light years away, or 23,498,359,696,812 miles from Earth.
