Surprisingly perhaps, it is fairly cool for a star. Betelgeuse is a red giant, meaning it is reaching the end of its life. When a star like our sun, a moderate Main Sequence Star begins to run out of fuel, there is a reaction in the collapsing core that briefly (in the lifetime of a star..briefly can be millions of years) causes the outer layers to expand outward. The gases cool off as they move farther from the core. Red light holds the least energy, which is why the star's outer layers turn red. It is also the coolest light.
Our sun will one day become a red giant like Betelguese, and its outer layers will expand far enough to engulf Mars.
One day, Betelgeuse will loose its outer layers in a nova, and all that will be left will be a white dwarf core.
Look up the Hertsprung-Russell diagram and you'll get more exact temperatures for red giants, but red stars of any type are the coolest.

∙ 14y agoGamma Cancri or Asellus Borealis (which is Latin for "northern donkey colt") has a spectral class of AV1V which means it is pretty high (Our Sun is a G2V). This would put the surface temperature at around 7,500-10,000 Kelvin

∙ 12y agoIts an awful lot hotter than England. Betelgeuse is a huge sun, many tens the size of ours and at the end of its life, possibly due to become a super nova

Where does the betelgeuse belong?
Rigel (Beta Orionis) is the brightest star in the constellation Orion and the sixth brightest star in the sky.It is a type B star and will have a temperature between 10,000 -> 30,000 KObservations have placed it's surface temperature at 12,130K. This equates to:21,374 degrees Fahrenheit11,857 degrees Celsius
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.
How can you tell if Rigel or Betelgeuse is hotter?
Rigel is hotter by a long way with a temperature of 11,000 Kelvin, whereas Betelgeuse is a cool 3,500 Kelvin
Is Betelgeuse a yellow star?
No, Betelgeuse is a red star.
Is Betelgeuse a dwarf planet?
Betelgeuse is a supergiant star.
What is temperature of Betelgeuse?
Betelgeuse ("Beetlejuice") has a surface temperature of around 3,500 Kelvin. (3,200º Celsius or 5,800º Fahrenheit)
What is the temperature of Betelgeuse?
Betelgeuse ("Beetlejuice") has a surface temperature of around 3,500 Kelvin. (3,200º Celsius or 5,800º Fahrenheit)
Is Betelgeuse warmer than the sun?
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
How are betelgeuse and pollux stars alike?
Both Betelgeuse and Pollux are close to the end of their life. Both of the stars are large and cold in surface temperature. One difference is that Betelgeuse is a red supergiant, and Pollux is an orange giant.
What does the red color of Betelgeuse mean?
The red colour means that it's surface temperature is cool < 3,700K. At that temperature, the spectrum of light is red.
Is betelgeuse hotter than a white dwarf?
No, the surface temperature of Betelgeuse is colder than the temperature of a white dwarf, the white dwarf is the hot core of a dead star. Also, red stars are always colder than white stars.
What is revealed by the red color of the super giant star called Betelgeuse's?
A red color, in a star, is associated with a low surface temperature.
What is the surface of betelgeuse?
3,500 Kelvin
What is the temperature of the betelgeuse star?
Betelgeuse is a red supergiant.Its mass is 18-19 solar masses and its diameter is about 936 times the sun.It's surface temperature is about 3,500 K about 3200 Celsius, 5800 Fahrenheit much cooler than our own sun but since the surface area is much larger the overall luminosity is about 100,000 brighter.
What are some surface features on Betelgeuse?
Betelgeuse is a red giant therefore its surface is of red color with some white sun spots.
Is Betelgeuse hotter than Rigel?
No, Rigel is hotter. Rigel is a blue star with a temperature of about 11,000 K, and Betelgeuse is a red star with a temperature of about 3,500 K.
What is the color and temperature of Betelgeuse?
Betelgeuse is located in the Orion constellation and is a red star. Red stars are generally the coolest of stars.
