Answer 2

Answer: A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km.

Explanation: The term light-year refers to the distance light travels in a vacuum in one year. Since light travels at slightly more than 186,000 miles (300,000 kilometers) per second, one light-year is roughly equal to 5.9 trillion miles (9.5 trillion kilometers).
