Rigel's effective temperature is 12100 K compared to the Sun's 5778 K. Since these temperatures are on the absolute scale, it is possible to say that Rigel is approx 2.1 times as hot.

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.
