Explanation:
Detailed explanation-1: -Light-year is the distance light travels in one year. Light zips through interstellar space at 186, 000 miles (300, 000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
Detailed explanation-2: -A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers). On the scale of the universe, measuring distances in miles or kilometers is cumbersome given the exceedingly large numbers being discussed.
Detailed explanation-3: -Speed of light = 300, 000, 000 m/s = 3 x 10 8 m/s. 1 light year = 3 x10 8 m/s x 31, 536, 000 s = 9.46 x 10 15 metres. 1 light year = 9.46 x 10 15 m.
