However, this is just an average. The actual time can vary slightly depending on:

* Earth's position in its orbit: Earth's orbit is slightly elliptical, so the distance between the Sun and Earth changes throughout the year.

* The Sun's activity: The Sun's activity can affect the speed of light, though the difference is very small.

So, while 8 minutes and 20 seconds is a good approximation, the exact time can fluctuate slightly.
