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.
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.
The sun is much smaller and cooler.
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.
Rigel, a blue supergiant star in the constellation Orion, has a surface temperature of approximately 11,000 to 12,000 Kelvin. This high temperature contributes to its bright blue color and significant luminosity, making it one of the most prominent stars in the night sky. Rigel's intense heat is a result of its massive size and rapid rate of nuclear fusion in its core.
Yes. Rigel's effective temperature is 12100 K compared to the Sun's 5778 K.
Procyon is not hotter than Rigel. Procyon, a main-sequence star, has an effective temperature of about 6,500 Kelvin, whereas Rigel, a blue supergiant, has an effective temperature of approximately 11,000 Kelvin. This makes Rigel significantly hotter than Procyon. Additionally, Rigel's higher temperature contributes to its blue color, while Procyon has a yellowish hue.

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.
Rigel is in the constellation Orion, not Centaurus. Please check your spelling and, if appropriate, resubmit.
