Blue stars are thought to be hotter than red stars primarily due to their temperatures and the spectral classification of stars. Blue stars emit light at shorter wavelengths, indicating higher energy and temperature, typically ranging from about 10,000 to 50,000 Kelvin. In contrast, red stars have longer wavelengths and lower temperatures, generally between 2,500 and 4,000 Kelvin. This difference in color is a direct result of the stars' temperatures, with hotter stars appearing blue and cooler stars appearing red.
What else can I help you with?
What is a clue to a stars temperature?
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
Is a blue star hotter than a red giant?
blue stars are hotter
True or false Red stars are hotter than whittish- blue stars?
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
Suppose you see two stars a blue star and a red star what can you conclude about the two stars?
The color of a star is influenced by its temperature, with blue stars being hotter than red stars. Therefore, you could conclude that the blue star is hotter than the red star. Additionally, blue stars typically have shorter lifespans than red stars.
Are blue stars cooler than red stars?
No, blue stars are hotter than red stars. In other words, red stars are cooler. Think of it as fire. The red one is hot, but the blue flame is RAGING hot.

Which is hotter red stars or whitish - blue stars?
White Dwarves and Blue giants are both hotter than Red giant stars.
Can blue stars get colder than planets?
No. Blue stars are the hottest stars, far hotter than any planet.

No, blue stars are hotter than red stars. In other words, red stars are cooler. Think of it as fire. The red one is hot, but the blue flame is RAGING hot.
Which is hotter blue stars or white stars?
Blue stars are hotter than white stars. Blue stars have surface temperatures ranging from 20,000 to 50,000 degrees Celsius, while white stars typically have temperatures around 7,500 to 10,000 degrees Celsius.
Why do white stars come between blue and yellow stars in an H-R diagram?
because blue is hotter than white
Is red stars cold?
No. Red stars emit less energy so they are cooler than hotter blue stars.
What are the names of the stars that are blue?
Some examples of blue stars include Rigel, Vega, and Sirius. Blue stars are typically hotter and more massive than other stars, giving them their distinct blue color.
