Stars can vary widely in temperature depending on their size and stage in their life cycle. The temperature of a star is typically measured using the Kelvin scale. Here are some general temperature ranges for different types of stars:
1) Blue Stars (Hotter):
- Blue stars are among the hottest stars.
- Temperatures can range from about 10,000 to over 40,000 degrees Celsius (18,000 to over 72,000 degrees Fahrenheit).
- Examples include some O-type and B-type main sequence stars.
2) Yellow/White Stars (Intermediate):
- Our Sun is an example of a yellow star.
- Temperatures for yellow and white stars like the Sun range from about 5,500 to 6,000 degrees Celsius (9,932 to 10,832 degrees Fahrenheit) for the Sun.
3) Red Stars (Cooler):
- Red stars are generally cooler than blue stars.
- Temperatures can range from about 2,500 to 4,000 degrees Celsius (4,532 to 7,232 degrees Fahrenheit).
- Examples include many M-type main sequence stars.
It's important to note that these temperatures are approximate, and the actual temperature of a star can vary based on factors such as its mass and stage of evolution. The temperatures mentioned here represent the effective temperature, which is a measure of the temperature of an idealized sphere that radiates energy at the same rate as the star. The core temperature of a star, where nuclear fusion occurs, is much higher than its surface temperature.
