When talking about stars, "cool" is a relative term. Betelgeuse has a variable surface temperature of 5,200 to 6,100 degrees Fahrenheit. Such a temperature may seem extremely hot to us and is easily hot enough to emit bright light but it is fairly cool as stars go. The comparatively low temperature of Betelgeuse means that it gives off less light per square meter than a hotter star would, but it makes up for it with its massive size, more than 900 times the diameter of the sun. As massive size means a large surface are and thus a huge output of light.
What else can I help you with?
How many light years away is betelgeuse?
Betelgeuse is approximately 600 light years from Earth.
How far is Betelgeuse from the sun?
Betelgeuse is about 640 light-years from the sun.
What is revealed by the red color of the supergiant star called Betelgeuse?
The red color of Betelgeuse indicates that it is a cooler star, emitting light at longer wavelengths in the red spectrum. This color indicates that Betelgeuse is a massive, aging star that is nearing the end of its life cycle.
How long does it take light to reach earth from Betelgeuse?
Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time at all in cosmic terms, but in terms of a HUMAN lifetime, it probably will NOT happen while we're alive to see it. But it could. In fact, Betelgeuse might have exploded 500 years ago, and we wouldn't know it for another 140 years!
How far away is Betelgeuse?
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.

How far away is Betelgeuse?
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.
How many light years is Betelgeuse from Capella?
Betelgeuse is approximately 430 light years away from Earth, while Capella is about 42.9 light years away. Therefore, Betelgeuse is around 387.1 light years farther away from Capella.
How many light years from earth is betelgeuse?
Betelgeuse is approximately 642.5 light years away from Earth.
What is the wavelength of light emitted from the surface of Betelgeuse?
The surface of Betelgeuse emits light across a broad range of wavelengths, including visible, infrared, and ultraviolet light. The dominant wavelength emitted by Betelgeuse is in the red region of the spectrum, specifically around 700 nanometers.
How long does it take for the light generated by the star Betelgeuse to reach Earth?
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
How long would it take to get to Betelgeuse?
No one really knows, because no one has ever been to Betelgeuse. It would take much more time than getting to Pluto.
How Many astronomical units is the sun from Betelgeuse?
Betelgeuse is 40,473,416.93376 AU' (Astronomical Units) from Earth.
What happens in the sun to produce light?
Nuclear fusion takes place, converting Hydrogen atoms into Helium atoms and releasing massive amounts of energy as light and heat.
