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: -Since light travels at about 186, 300 miles per second, with 86, 400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5, 875, 000, 000, 000 miles.
