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.
Betelgeuse is approximately 600 light years from Earth.
Betelgeuse is about 640 light-years from the sun.
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.
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!
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.

Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.
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.
Betelgeuse is approximately 642.5 light years away from Earth.
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.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
No one really knows, because no one has ever been to Betelgeuse. It would take much more time than getting to Pluto.
Betelgeuse is 40,473,416.93376 AU' (Astronomical Units) from Earth.
Nuclear fusion takes place, converting Hydrogen atoms into Helium atoms and releasing massive amounts of energy as light and heat.
