What type of star is betelgeuse?
Betelgeuse is the ninth brightest star in the night sky and second brightest star in the constellation of Orion.It has a spectral type of M2 and is a red supergiant.See related question for more information.
What color is Betelgeuse?
Betelgeuse is one of the prominent stars in the Constellation of Orion.It is actually ORANGE-RED in color.It belongs to the spectral class K ( with temperature 4,900 - 3,500 degrees Kelvin )Betelgeuse is a semiregular variable star located approximately 640 light years from the Earth.It has a spectral type of M2 and a temperature of about 3,500K which means it has a colour of red.
How does the temperature of betelgeuse compared to the temperature of rigel?
Betelgeuse, a red supergiant star, has an effective surface temperature of around 3,500 Kelvin, while Rigel, a blue supergiant, has a much higher surface temperature of about 11,000 Kelvin. This significant difference in temperature is due to their stages in stellar evolution and their respective spectral classifications, with Betelgeuse being cooler and redder, and Rigel being hotter and bluer. Consequently, Rigel emits more energy than Betelgeuse, influencing their brightness and appearance in the night sky.
The spectral type of a star measure?
The spectral type of a star indicates its surface temperature and helps classify it based on the characteristics of its spectrum. It is determined by analyzing the patterns of absorption lines in the star's spectrum, which correspond to different elements present in its atmosphere. Spectral type is important for understanding the physical properties and evolutionary stage of a star.
What does the spectral type of a star measures what?
The spectral type of a star measures its temperature and determines its color, luminosity, and size. It is determined by the characteristics of the star's spectrum, such as the absorption lines caused by elements in its atmosphere. Astronomers use spectral types to classify stars based on their physical properties.

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).
Is spectral type k hotter then spectral type a?
No. K spectral type stars (which are orange) temperature is ranging from 5,000-3,500. A spectral type stars (which are blue-white) temperature is ranging from 7,500-11,000.
How does the Sun compare with Betelgeuse?
The Sun is a yellow dwarf - Betelgeuse is a red supergiantThe Sun has a spectral type of G2V, Betelgeuse is M2Betelgeuse is about 1,000 times larger than our Sun.Betelgeuse will explode as a supernova our Sun won't.Our Sun has a temperature of about 5,700 Kelvin, Betelgeuse is 3,500 K.Betelgeuse is only a few million years old, the Sun is 4.5 billion years old.
What type of supernova will Betelgeuse be?
Betelgeuse is expected to end its life in a supernova explosion, likely as a Type II supernova due to its massive size and age. This type of supernova occurs when a massive star exhausts its nuclear fuel and collapses under its own gravity.
What type of stars are Betelgeuse and Rigel?
Betelgeuse is a red supergiant star and the Rigel is a blue supergiant. Both are in the same constellation Orion

What is the spectral type of Alpha Centauri A?
G2v / k1v
What type of line does the photon move in?
Spectral line
What spectral class of stars are the hotteset?
Type-O are the hottest but there are very few. Then type-B, there are more of them but still not a lot. Then you have type-A, which are very common, then F, then G like the Sun, then K and then the coolest common ones, type M which are the red stars like Betelgeuse.
