Some comets can survive temperatures twice as hot as a kiln
Small comets known as sungrazers can survive a perilous journey through the sun's outer atmosphere, enduring temperatures exceeding 2,000 degrees Celsius while traveling at nearly 400,000 miles per hour.
Kreutz sungrazers are a unique group of comets that dive within 158,000 kilometers of the sun's surface, passing directly through the searing solar corona. During this close approach, these icy travelers endure temperatures twice as hot as a ceramic kiln. While many fragment due to the sun's intense gravity, survivors can brighten by 1,000 times as their ice turns directly into gas at a rate of 10 kilograms per second.
