The light-year is a unit of length used to express astronomical distances. It is about 9.5 trillion kilometres or 5.9 trillion miles. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days). Because it includes the word year, the term light-year is sometimes misinterpreted as a unit of time.
Light travels at a speed of 186,000 miles (299,338 Km) a second or 700 million miles (1,126,540,800 Km) an hour. The distance from the Earth to the Moon is about 239,000 miles (384,633 kM). This seems pretty fast and indeed theory says that nothing can travel faster than the speed of light.
