1 light year = 9.46 x 10¹⁵ m Explanation
Distance that light travels with velocity of 3 x 10⁸ m/s in 1 year. The distance light travels in the course of a year is called a light-year. A light-year is a measure in terms of both time and distance. It takes about 1 second for the light from moon to reach our eyes, it means the moon is about 1 light-second away. Light from Sun take about 8 minutes to reach our eyes, so the sun is about 8 light-minutes away. Light from the nearest star system requires approximately 4 years to reach here, so the light w
