Answer:
8 Earth years
Explanation:
A light year is the distance that light travels in one (Earth) year. As such, a light is not a speed but rather a measure of distance. The speed of light is just shy of three 300 000 000 metres per second in a vacuum and, even so, to reach a star at a distance of 8 light years would take 8 Earth years.
The closest star, the Sun, is a mere 8 light minutes from the Earth, and the next closest star, Proxima Centauri, is 4.2 light years away.
