The average distance from the Sun to the Earth is about 149.6 million kilometers (93 million miles). If we consider the speed of light as approximately 299,792 kilometers per second (186,282 miles per second), we can calculate how long it takes for light from the Sun to reach the Earth.
Using the average distance and the speed of light, we can calculate the time it takes for light to travel from the Sun to the Earth by dividing the distance by the speed of light:
149.6 million kilometers / 299,792 kilometers per second ≈ 499.0 seconds
So, on average, it takes about 499 seconds, or roughly 8 minutes and 19 seconds, for light to travel from the Sun to the Earth. This is often referred to as the "light travel time." Keep in mind that this calculation considers the average distance and assumes light travels in a straight line, ignoring factors such as the elliptical orbit of the Earth and variations in the Earth-Sun distance throughout the year.
