Earth's distance from the Sun varies between about 147 and 152 million kilometers. Given the speed of light as 299,792,458 m/sec and the Sun's radius of 696,000 km, this makes the time taken for the journey (from the Sun's surface to the Earth's) between 8.14 and 8.42 minutes. On an average, it is about 8.28 minutes or 8 minutes and 17 seconds.
