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, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×1012 km), or 5.88 trillion miles (5.88×1012 mi).
Detailed explanation-3: -Lightyears. A common method for measuring distance in space is to measure how far light travels in one year: known as a lightyear, which is around 9.5 trillion km. If you want to be precise, the IAU regards a year as 365.25 days, making a lightyear 9, 460, 730, 472, 580, 800m.
