How long does it take the sun's light to reach earth?


The distance from the Earth to the Sun varies because the Earth's orbit about the Sun is elliptical.At it's closest, the distance is 91,402,000 miles and it's farthest distance it is 94,512,000 miles.This gives an average distance of 92,957,000 miles. Light travels at 186,282 miles per second. Dividing the average distance by the speed of light gives 499.01225 seconds which is 8.3168708 minutes.

Rounded off, let's say 8 minutes and 18 seconds.
