The star is too far away to cause harm to us. Betelgeuse does not have any planets orbiting it, as far as we know. Additionally, the position of Betelgeuse is RA 05 h 55 m 10.3053 s, dec+07° 24'25.4” [1-4].
Betelgeuse is an enormous star. If we were to place it at the center of our solar system, it would extend all the way to Jupiter. The star's size, combined with its position in our galaxy, the Milky Way, allows astronomers to study Betelgeuse in better detail than most stars.
While it is large and bright, Betelgeuse isn't actually that hot, with a surface temperature of about 6,000 degrees Fahrenheit (over 3,300 degrees Celsius) – cooler than our Sun's roughly 10,000-degree Fahrenheit (over 5,500 degree-Celsius) surface.
Today, Betelgeuse is one of the largest known stars, measuring more than 700 million miles (1.2 billion kilometers) in diameter. If Betelgeuse were to replace the sun at the center of the solar system, it would reach all the way to Jupiter. On the other hand, the star is no longer anywhere near as hot as it used to be.
Betelgeuse, which is estimated to be around 15 solar masses, is one of the most prominent stars in the night sky, clearly visible from both the northern and southern hemispheres.

How many planets are around Betelgeuse?
The star is too far away to cause harm to us. Betelgeuse does not have any planets orbiting it, as far as we know. Additionally, the position of Betelgeuse is RA 05 h 55 m 10.3053 s, dec+07° 24'25.4” [1-4].
“We conclude that Betelgeuse should currently be in a late phase (or near the end) of the core carbon burning,” the paper notes. “After carbon is exhausted in the core, a core-collapse leading to a supernova explosion is expected in in a few tens [of] years.”
Betelgeuse is a red supergiant around 500 to 600 lightyears from Earth and makes up the left shoulder of the constellation Orion. It is expected to go supernova at some point in the next 100,000 years.
The concept of a habitable zone really doesn't apply to a star like Betelgeuse. In addition to being a highly unstable and variable supergiant, it's a runaway star, suggesting that it was formerly a member of a multiple star system with a companion star that went supernova.
To the ancient Egyptians, the constellation was Osiris, a god and primeval king in the culture's mythology. In some myths originating in the Americas, Betelgeuse represented a wound on Orion, perhaps because of the star's red color.
Bottom line: Betelgeuse is due to explode as a supernova someday. When it does explode, it'll be bright enough from our earthly vantage point to shine during the day. But it's far enough away that Earth won't be in any danger.
Betelgeuse's Supernova Timeline: While it is challenging to accurately determine the exact year when Betelgeuse will go supernova, astronomers have made predictions based on observations and scientific models. As of the latest research, it is believed that the supernova event could occur within the next 100,000 years.
A pulsating semiregular variable star, Betelgeuse is subject to multiple cycles of increasing and decreasing brightness due to changes in its size and temperature.
Astrologically speaking, Betelgeuse represents success, fame, and influence. "If you have this prominent in your chart, you can take this as good news," Lang says. "It represents gifts, special abilities, and even tendencies for success."
Although some hype up Betelgeuse's looming doom, its coming explosion, called a supernova, might not happen for at least tens of thousands of years, if not more like some 100,000.

Dr Stanimir Metchev also said that it was unlikely that it would happen in our lifetime. He said the last stages of a star's life can last hundreds of thousands of years.
One type, named Type 1a supernovae, involves a binary star where one of the pair is a white dwarf. And while supernovae of all types usually involve a single explosion, astronomers have found something that breaks that mould: A Type 1a supernova that may have detonated twice.
How long would it take for us to know if Betelgeuse exploded?
Answer and Explanation: It is given that the star Betelgeuse is about 600 light-years away. When it explodes, the electromagnetic radiation coming from it will take 600 years to reach us. Therefore, the explosion will be noticed by us after 600 years.
While Betelgeuse's supernova is not expected to cause direct harm to life on Earth, it could potentially have some atmospheric effects. The explosion would release a burst of ultraviolet radiation, which could deplete the ozone layer temporarily.
What would it look like if Betelgeuse went supernova?
The star is around 500 light-years away. Following an explosion, we first would detect a rain of massless particles called neutrinos, which would be harmless to us. After that, the star would quickly brighten. After one or two weeks it would shine with about the same brightness as the full Moon.
