your mom is hotter than all the stars combined!
Rigel, has a surface temperature of 12100 K, approx 3.1 times as hot as Aldebaran (3910 K).
Rigel: 71 solar radiiAldebaran: 44.2 solar radii.So Rigel is almost twice the size of Aldebaran.See related link for a pictorial of the difference (Section 5).
No, Rigel is hotter than the Sun. Rigel is a blue supergiant star with a surface temperature that is much hotter than the Sun.
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.
It's hotter

yes
Rigel: 71 solar radiiAldebaran: 44.2 solar radii.So Rigel is almost twice the size of Aldebaran.See related link for a pictorial of the difference (Section 5).
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.
The absolute magnitude of Rigel is -7.92 while that of Aldebaran is -6.41. This means that Rigel is approx 4 times brighter than Aldebaran - technically. So the question is based on a flawed grasp of absolute magnitude.

No, Rigel is hotter than the Sun. Rigel is a blue supergiant star with a surface temperature that is much hotter than the Sun.
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.
It's hotter
Rigel is much hotter. Red is the lowest temp. blue and white are the hottest
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.
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).
