Rigel is hot by "normal" stars but it is not the hottest, this distinction goes to a star named Cygnus OB2-12. See related questions.
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.
What is the hottest star including Rigel?
The hottest star is known as H1504+65 (and also sometimes as WD 1501 +663). The star, in the constellation Ursa Minor, has a surface temperature estimated at 200,000 K. No current model of stellar evolution can explain this tar satisfactorily.By way of comparison, the effective temperature of Rigel is "only" 12,100 K.
What is the tenperature of rigel star?
The surface temperature of Rigel, a blue supergiant star in the constellation Orion, is estimated to be around 12,100 Kelvin. It is one of the hottest stars visible to the naked eye from Earth.
Are there any aliens on Rigel?
There is currently no scientific evidence to suggest the existence of aliens on Rigel or any other star system. The search for extraterrestrial life continues to be a topic of interest for astronomers and scientists.

What are the characteristics of rigel?
Rigel is a blue supergiant star located in the constellation of Orion. It is one of the brightest stars in the night sky and is approximately 860 light-years away from Earth. Rigel is part of a multiple star system, with a faint companion star orbiting around it.
Hotter stars tend to be what color?
The color of a star comes from its temperature. The coolest stars appear red, while the hottest stars are blue. And for a star, the only thing that defines the temperature of a star is its mass. Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it's going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky. Astronomers calculate that Rigel is approximately 700 and 900 light-years away, and yet it appears almost as bright as a star like Sirius which is only 8.3 light-years away. The temperature of Rigel is approximately 11,000 Kelvin; it's this high temperature that accounts for Rigel's color. Rigel puts out about 40,000 times the energy of the Sun.
