What's five times hotter than the sun and capable of sending a DeLorean back to the future? Yep, the answer is a bolt of lightning, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit). The sun, on the other hand, is eclipsed in this case - its surface temperature is just 6,000 kelvins (10,340 degrees Fahrenheit).
1 A bolt of lightning lasts on average for about one 10,000th of a second but could light a 100 Watt light bulb for three months. 2  Lightning travels through the air at around 270,000 mph-that's around 75 miles every second. 3  Lightning is hotter than the surface of the sun reaching temperatures of around 30,000 Â°C.
