Explanation

One light-year is the distance light travels in one year in vacuum, which is approximately 9.46 × 10^12 kilometers. This is a standard astronomical unit for measuring interstellar distances. The other values (9.47, 9.48, 9.50) are close approximations but not the precise accepted value.
