Which star is hotter Rigel (a Supergiant) or Aldebaran (a Giant)?
Rigel is hotter than Aldebaran. Rigel, a blue supergiant, has a surface temperature of about 11,000 K, while Aldebaran, a red giant, has a surface temperature of around 4,000 K. The difference in their temperatures is due to their spectral classifications, with blue stars being significantly hotter than red stars. Thus, Rigel is the hotter of the two.
Which star is hotter rigel or aldebaran?
Rigel, has a surface temperature of 12100 K, approx 3.1 times as hot as Aldebaran (3910 K).
Is Rigel bigger than Aldebaran?
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).
Is the Sun cooler then Rigel?
No, Rigel is hotter than the Sun. Rigel is a blue supergiant star with a surface temperature that is much hotter than the Sun.
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.

Rigel aldebaran Sirius Antares KY cygni betelgeuse pollux arrange in ascending order?
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.
Why is Rigel appears brighter than aldeberan even though aldeberan is technically brighter than Rigel?
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.

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.
Why does Rigel shine as brightly as Betelgeuse even though Rigel is much smaller?
It's hotter
Is procycon hotter than rigel?
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.
