How hot can a star be?
The hottest stars may be almost 100,000 (100 thousand) degrees Fahrenheit. That big number means the stars are far, far hotter than anything you have ever seen or felt here on Earth. Our Sun is about 10,000 (10 thousand) degrees F — much cooler than the hottest stars, but still super hot! The oven in your house can’t come close to this blazing temperature. But those temperatures are just at the surface. Deep inside, the cores of stars are even hotter. Some stars can be about 200,000,000 (200 million) degrees inside, and the Sun is around 25,000,000 (25 million) degrees at its core. For short times, as stars that are much larger than the Sun are ending their lives in huge explosions, the inside temperature could reach as high as 10,000,000,000 (10 billion) degrees. How high up is a star? Our nearest star, the Sun, is 93,000,000 (93 million) miles from Earth. That is a really long way, but all the other stars are much much much much MUCH farther away. I can’t give just one distance (wel
