Question

Blue stars are seem to be larger almost than red and yellow stars. Blue stars might be' about more than 10, 000 degres.celcius, Unlike our sun it's surface is aproximity 🌡5, 600 degres celcius, Such as A large star, like Stephenson 2-18, A Shocking hot, Red Hyper Super Giant Star, it's temperature, is estimated 🌡200, 300 degres celcius, which us extremely hot!

Answer 1

It seems there are a few inaccuracies in your description of stars, particularly regarding their temperatures and classifications. Let’s clarify some points.

1. Color and Temperature: The color of a star is indeed related to its temperature. Blue stars are among the hottest, with surface temperatures often exceeding 10,000 degrees Celsius. In contrast, red stars, such as red dwarfs, are much cooler, typically around 2,500 to 3,500 degrees Celsius. Yellow stars, like our Sun, have temperatures around 5,500 to 6,000 degrees Celsius.

2. Star Sizes: Blue stars are often larger in size compared to many red and yellow stars. However, this is not a strict rule as there are many types of stars with varying sizes and classifications.

3. Stephenson 2-18: Stephenson 2-18 (St2-18) is indeed a very large star, classified as a red supergiant. Its temperature isn’t as high as you mentioned; it is estimated to be around 3,200 degrees Celsius, which is typical for red supergiants.

4. Red Hypergiants: Red hypergiants like Stephenson 2-18 are characterized by their immense size rather than extremely high temperatures as found in blue giants. Generally, hypergiants can have a range of temperatures, but they are cooler compared to the hottest blue stars.

In summary, blue stars are hot and massive, red stars are cooler, and red supergiants like Stephenson 2-18 are large but not as hot as blue stars. Let me know if you have more questions about stars or any other topic!
