What are some surface features on Betelgeuse?
Betelgeuse is a red giant therefore its surface is of red color with some white sun spots.
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 many square miles is Betelgeuse?
Betelgeuse has a radius of over 510 million miles, giving a surface area of about 3.27 × 1018 square miles.
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.

How hot is Betelgeuse on its surface?
3500 k (kelvin), 1 kelvin is -272.15°C

What are facts about Betelgeuse?
Betelgeuse is the eighth brightest star in the night sky and the second brightest star in the constellation of Orin. It is classified as a Red Giant. Astronomers believe that Betelgeuse is only 10 million years old, but has evolved rapidly due to its high mass. Betelgeuse is made from: Helium, Carbon, and Oxygen. Astronomers don't know when but they are sure that Betelgeuse will explode and become a SuperNova. Betelgeuse is 700 million miles in diameter and the surface temperature is 6,000 degrees Fahrenheit. Its luminosity is about 10,000 times the Sun and it's the first star to be directly imaged by a telescope. Finally Betelgeuse is visible in winter skies from the Northern Hemisphere in the constellation Orion. Hope that Helped You :)
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.
How can betelgeuse look sso bright if it is far away and has a cool surface?
Several things to consider:-- Because of its ENORMOUS size. We believe that Betelgeuse is about as largeas the orbits of the Asteroid Belt. So if Betelgeuse sat exactly where the sun sits,then Mercury, Venus, the Earth, and Mars would all be inside of it.-- Because it's so close to us. Betelgeuse is roughly 800 light-years from us. That'san enormous distance, but actually pretty close as stars go.-- Because it's so hot. The surface temperature of Betelgeuse is estimated at 3,600 K,which is roughly 3,325° Celsius and 5,960° Fahrenheit. That's pretty cool for a star,but you still wouldn't want to touch it.
