The distance from Earth to the Sun varies because Earth’s orbit about the Sun is elliptical. At its closest, the distance is 91,402,000 miles, and its farthest distance 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.
However, the Sun is a sphere, not a disk. The edges of the sphere curve away from Earth. Light from the edge of the Sun takes more than two seconds longer to reach us than light from the center of its surface.
