A light-year is the distance that light travels in a vacuum in one Julian year (365.25 days).
Light travels at approximately 299,792 kilometers per second in a vacuum.
Light-years measure vast cosmic distances, so 100,000 kilometers, while large on Earth, is minuscule compared to interstellar or intergalactic scales.
To convert kilometers to light-years, you divide the distance in kilometers by the number of kilometers in one light-year (approximately 9.461 trillion km). 100,000 km is 0.0000 light-years.
