There is more than one star in the Rigel "system". The main star, in terms of brightness, is Rigel A. That has a surface temperature of about 12,000 degrees Celsius.
The brightness of a star depends not just on its surface temperature, but also on its size and distance from Earth. While Rigel is hotter than the Sun, it is also a much larger and more luminous star. Therefore, even though the Sun is cooler than Rigel, it appears brighter to us because it is much closer and has a larger luminosity due to its size.
it is a dwarf planet the size of a supergiant.
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).
Rigel is a blue supergiant star with a surface temperature of around 12,100 Kelvin. It emits most strongly in the ultraviolet part of the spectrum at around 200 nanometers due to its high temperature.
Rigel has a radius which is 79 times as large as the sun - so that its volume is half a million times as great. The Rigel's effective temperature is 12100 K compared to the sun's 5778 K : about 2.1 times as hot.
The sun is much smaller and cooler.
Rigel is approximately 120,000 times brighter than the Sun. This high luminosity is due to Rigel's much larger size and higher temperature compared to the Sun.
Rigel: 12100 K.Sun: 5778 K.
Rigel's temperature is: 11,000 K And the colour is: Blue. To be exact Rigel is a Blue supergiant.
No, Rigel is hotter than Betelgeuse. Rigel is a blue supergiant star with a surface temperature of around 12,000 Kelvin, while Betelgeuse is a red supergiant with a surface temperature of around 3,500 Kelvin.
Yes. Rigel's effective temperature is 12100 K compared to the Sun's 5778 K.

Rigel is in the constellation Orion, not Centaurus. Please check your spelling and, if appropriate, resubmit.
No. Rigel's effective temperature is 12100 K compared to the Sun's 5778 K.
Yes, Vega is hotter than Rigel. Vega is a main sequence star with a surface temperature of around 9600 K, while Rigel is a supergiant star with a surface temperature of around 12,100 K.
