Temperature of Rigel?
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 surface temperature of the star Rigel is about 15000celiusThe sun has a temperature of about 6000celius Why does the sun appear so much brighter?
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.
Is rigel a dwarf planet or a supergiant?
it is a dwarf planet the size of a supergiant.
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).
The star Rigel radiates most strongly at about 200 nanometers How hot is it?
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.
How does our Sun differ in size and temperature from the star Rigel?
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.
How does the sun differ in size and temperature from other stars like rigel?
The sun is much smaller and cooler.
How much brighter is rigel than the sun?
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.
What is temperature of rigel and sun?
Rigel: 12100 K.Sun: 5778 K.
What is the color and temperature of the rigel?
Rigel's temperature is: 11,000 K And the colour is: Blue. To be exact Rigel is a Blue supergiant.
Is Betelgeuse hotter than Rigel?
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.
Is Rigel temperature higher than the sun?
Yes. Rigel's effective temperature is 12100 K compared to the Sun's 5778 K.

What is the size of star Rigel Centaurus?
Rigel is in the constellation Orion, not Centaurus. Please check your spelling and, if appropriate, resubmit.
Is Rigel cooler than the sun?
No. Rigel's effective temperature is 12100 K compared to the Sun's 5778 K.
Is Vega Hotter the Rigel?
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.
