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.

How can i compare and contrast the apparent and absolute magnitude of stars?
Apparent magnitude measures how bright a star appears from Earth, influenced by its distance and intrinsic brightness, while absolute magnitude reflects a star's true brightness at a standard distance of 10 parsecs. To compare the two, consider that a star may have a high apparent magnitude (appearing bright) if it's relatively close, even if it has a low absolute magnitude (inherently dimmer). Conversely, a distant star with a high absolute magnitude may appear faint from Earth. Analyzing both magnitudes helps astronomers understand a star's distance, size, and luminosity.
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.
Why does a cool distant supergiant star such as betelgeuse have a high luminosity?
Betelgeuse, a cool distant supergiant star, has a high luminosity primarily due to its large size and surface area. Despite its relatively low temperature, its vast volume allows it to emit a significant amount of energy. The combination of its expansive radius and the Stefan-Boltzmann Law, which states that a star's luminosity increases with the fourth power of its temperature, results in Betelgeuse's impressive brightness. Thus, even with a lower temperature, its sheer size compensates, leading to high luminosity.
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.
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.
How much brighter is betelgeuse than the sun?
Betelgeuse, a red supergiant star, is approximately 10,000 times brighter than the Sun. Its immense brightness is due to its large size and high luminosity, which allows it to outshine our Sun considerably. While the Sun is the brightest object in our sky, Betelgeuse's inherent brightness makes it one of the most luminous stars observable from Earth.
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.
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 high temperature but high luminosity?
The red giants like Betelgeuse and Antares are bright and - relatively - cool.
What is a Betelgeuse a star of high luminosity?
Betelgeuse is a red supergiant star located in the constellation Orion, known for its high luminosity and distinctive reddish hue. It is one of the largest and most luminous stars visible to the naked eye, with a brightness approximately 1,000 times that of the Sun. Betelgeuse is nearing the end of its life cycle and is expected to eventually explode as a supernova, which will be a spectacular event visible from Earth. Its size and brightness make it a key object of study in understanding stellar evolution.
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.
Why are Betelgeuse and Rigel so bright but so far away?
Betelgeuse and Rigel are exceptionally bright stars due to their intrinsic luminosity, which is a measure of the total amount of energy they emit. Both are massive stars in later stages of their evolution, with Betelgeuse being a red supergiant and Rigel a blue supergiant, leading to their high brightness. Despite their great distances from Earth—approximately 640 light-years for Betelgeuse and about 860 light-years for Rigel—their vast energy output makes them appear prominent in our night sky. Their brightness is a combination of their size, temperature, and the intense energy they produce.
