Answer:
A light-year is a unit of distance. It is the distance a light photon travels in the vacuum in one Julian year. Denoted by ly, the value of one light-year is constant. The term light-year is often used in astrophysics to measure the distance between two astronomical objects.
Light travels at a velocity of about 300,000 kilometres (km) per second. So in a year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.
