Lightning can travel up to 93,000 miles (150,000 kilometers) per second and reach temperatures of 54,000 degrees Fahrenheit (30,000 degrees Celsius), more than four times hotter than the surface of the sun.
Lightning and thunder occur simultaneously, but because light travels faster than sound, we see lightning first. Count the seconds between a flash of lightning and a clap of thunder and divide by five to estimate how far away in miles the storm is. Divide by three for kilometers
