Here's why:

* Star Color and Temperature: A star's color is directly related to its surface temperature.

* Red Stars: These are the coolest stars, with surface temperatures ranging from about 2,500 to 3,500 degrees Celsius.

* Other Colors: As stars get hotter, they change color:

* Orange: 3,500 to 4,500 degrees Celsius

* Yellow: 4,500 to 6,000 degrees Celsius

* White: 6,000 to 7,500 degrees Celsius

* Blue: 7,500 to 10,000 degrees Celsius

* Blue-White: Above 10,000 degrees Celsius

Remember, even the coolest red stars are incredibly hot by our standards!
