A blue star is hotter than a red star. The color of a star indicates its surface temperature, with blue stars having temperatures exceeding 10,000 degrees Celsius, while red stars typically have temperatures around 2,500 to 3,500 degrees Celsius. The higher energy output and temperature of blue stars result from their larger mass and more intense nuclear fusion processes occurring in their cores.

The color of the star can be indication of the?
The star's temperature. The more blue the star is the hotter it is. Pure blue stars get up to around 18,000 k. The more red the star is the cooler it is. Pure red stars can get up to around 2,500 k. White, yellowish color stars are in the middle.
What is the surface temperature of a yellow star?
The surface temperature of a yellow star typically ranges from 5,000 to 6,000 degrees Celsius. This temperature range is lower than that of hotter stars like blue or white ones, but higher than cooler stars like red dwarfs.
How can you tell if Rigel or Betelgeuse is hotter?
You can tell if Rigel or Betelgeuse is hotter based on their color. Rigel appears blue-white, indicating a hotter temperature, while Betelgeuse appears orange-red, suggesting a cooler temperature. Additionally, the spectral class of Rigel (B8Ia) is hotter than Betelgeuse's spectral class (M1-2Ia).
What color is an O star?
An O star is typically blue in color, and is one of the hottest types of stars with surface temperatures exceeding 30,000 K. The color of a star is a result of its temperature, with hotter stars appearing blue and cooler stars appearing red.
What star is hotter a star giving off red light or blue light?
That question is a little tricky. What is certain is that if the light is coming from a hot object like a glowing heater element, yellow light indicates that the element is hotter. It is also true that a single photon of yellow light carries more energy than a single photon of red light and is "hotter" in that sense. So in general, yellow light is hotter, but if you are simply talking about narrowband filtered light from a single source, a human will not ordinarily be able to sense the difference, and which color is more intense will depend on the spectrum of the light source.
Is a blue star hotter than a red giant?
blue stars are hotter
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.
A white blue star is hotter than a red stra?
The blue star is the hottest.
What can be said with certainty about a red star and a blue star?
A red star is cooler and has a lower temperature compared to a blue star, which is hotter. Red stars are typically older, while blue stars are younger. The color of a star is determined by its surface temperature, so these differences in characteristics between red and blue stars are consistent.
Is a white-blue star is hotter than a red star?
Yes it is
Is a red giant hotter than a blue star?
yes
What color star is hotter a red star of a blue star?
A blue star is hotter than a red star. Blue stars have higher surface temperatures, typically exceeding 10,000 Kelvin, while red stars have lower surface temperatures, usually below 4,000 Kelvin. The color of a star is an indication of its temperature, with blue stars being the hottest and red stars being the coolest.
Is the sun or a blue star hotter?
The blue star is hotter
Why is a blue star hotter than a white star?
It's not. White is the hottest. Then blue, yellow orange, red.
Which star is hotter a red star or a blue star?
a blue star is hotter then a red star because it is younger and thus has more energy. a good example of this is when you look at a flame on a lighter you see blue light at the bottom because blue is hottest and closest to the heat source whereas the red-orange flame at the top is farther away from the heat source and thus is not as hot as the blue.
Which star is hotter red or orange?
Blue stars are the hottest, followed by white stars, then yellow stars like the sun, and lastly red and orange stars which are cooler in temperature.
What is the ralation of color to a star's temperature?
Generally, the more blue a star is then the hotter it is, and the more red it is then the cooler it is.
