Because of its ENORMOUS size. We believe that Betelgeuse is about as large as a the orbits of the Asteroid Belt, so if Betelgeuse were here in our own solar system, it would consume Mercury, Venus, Earth and Mars, and probably destroy Jupiter as well.
As stars go, the 800 light-year distance to Betelgeuse is not that far away, although we wouldn't want it to be any closer. When Betelgeuse becomes a supernova, it will likely outshine the Moon.

What are the names of the stars that are larger than Betelgeuse?
Here are a few:T Cephei, VV Cephei, VY Canis Majoris, NML Cygni, WOH G64, and V059 Cassiopae. ... Mu Cephei, Mu Cephei A, ... There are certainly an extremely high number of stars that are bigger than Betelgeuse in the known universe alone.

Is Betelgeuse bigger than Jupiter?
Betelgeuse is a red super giant, relatively luminous, and one of the largest stars known. For comparison, if the star were at the center of our solar system its surface might extend out to between the orbits of Mars and Jupiter, wholly engulfing Mercury, Venus, Earth and Mars. Astronomers believe Betelgeuse is only a few million years old, but has evolved rapidly because of its high mass.Betelgeuse is one of the most luminous stars known. It is a red giant expected to go supernova possibly within the next one million years. It has been known for over two hundred years as a very "restless" star, varying in brightness, and varying in diameter, too (it is difficult to give an exact measurement for the star, because it is constantly changing).Betelgeuse is a red super-giant star "relatively" close to Earth; ONLY 640 light years away.The larger the star, the more quickly it dies. Betelgeuse is very young as stars go, less than ten million years old. It will most likely die in a supernova explosion within the next few thousand years; in fact, it may have already done so, and the light of that explosion could be on the way. When this happens, Betelgeuse will be brighter than the full moon. Considering its probable fate, we wouldn't want it to be any closer!Betelgeuse is easily visible; it is the red star in the shoulder of Orion.See related questions.
What are highly luminous stars tends to be?
Highly luminous stars tend to be massive and are often situated in the upper regions of the Hertzsprung-Russell diagram, typically in the blue supergiant or red supergiant categories. They have high temperatures and emit large amounts of energy, resulting in their brightness. These stars often have short lifespans, burning through their nuclear fuel rapidly compared to less luminous stars. Examples include stars like Betelgeuse and Rigel.
Is a high magnitude star more dense than a low magnitude star?
Magnitude is a measure of brightness, there is no relationship with density.
What is the luminosity of Betelgeuse?
Betelgeuse has a luminosity that is around 100,000 times that of the Sun. It is classified as a red supergiant star and is one of the brightest stars visible to the naked eye. Despite its high luminosity, Betelgeuse is also known for its variability in brightness.
Why is Betelgeuse so luminous?
Betelgeuse is luminous because it is a red supergiant star in the late stages of its evolution. Its large size and high brightness are due to its immense amount of energy being produced as it fuses heavy elements in its core, leading to its intense brightness compared to smaller, main-sequence stars.
Why does a cool distant supergiant star such as Betelgeuse have such a high apparent magnitude?
Betelgeuse, despite being a cool supergiant star, has a high apparent magnitude because of its immense size and luminosity. Its large size means it emits a lot of light, making it visible from great distances. Additionally, its red color and irregular variability can also contribute to its higher apparent magnitude.
Which stars are very cool but very luminous?
Red supergiant stars, such as Betelgeuse and Antares, are examples of stars that are very cool in temperature while still being extremely luminous due to their large size and high brightness. Despite their cool surface temperatures, they radiate a tremendous amount of energy into space.
What type of stars has high temperature but high luminosity?
The red giants like Betelgeuse and Antares are bright and - relatively - cool.
Why does a cool distant super giant star such as Betelgeuse have such a high apparent magnitude?
Despite its distance and size, Betelgeuse has a high apparent magnitude because of its immense luminosity. It is a massive and highly luminous red supergiant star, shining brightly due to its large surface area and energy output. This makes it appear bright in our sky despite being relatively far away.
What type of stars has low temperature but high luminosity?
The red giants like Betelgeuse and Antares are bright and - relatively - cool.
What type of stars low temperature but high luminosity?
The red giants like Betelgeuse and Antares are bright and - relatively - cool.
What is a word brightness in a sentence?
It depends on what the sentence is: The brightness of the sun is blinding. The word brightness would be an adjective.
Will how high the brightness is on an iPod Touch affect the battery life?
Yes, it will. The higher the brightness. the less the battery life will be.
How old is Betelgeuse?
Betelgeuse ("beetlejuice") is believed to be only a few million years old (~ 8.5 million) due to it's high mass. It is also believed, that it may become a supernova within a time frame where it could be observed by human civilization.
Could Betelgeuse support life?
Betelgeuse is a red supergiant star with a high mass and unstable nature, making it unlikely to support life as we know it. Its intense radiation, strong stellar winds, and eventual explosive end as a supernova would not provide a stable environment for life to exist.
