Voici pourquoi:
* Stellar Color and Temperature: A star's color is directly related to its surface temperature.
* Red Stars: Red stars are the coolest, with surface temperatures ranging from about 2,500 to 3,500 degrees Celsius.
* Other Colors: As stars get hotter, they become:
* Orange
* Yellow (like our Sun)
* Blanc
* Blue (the hottest)
Think of it like a piece of metal being heated. As it gets hotter, it glows red, then orange, then yellow, and finally white-hot. The same principle applies to stars!
