Answer and Explanation: No, Betelgeuse is not the biggest star. Although it is a very large star known as a red supergiant, its radius of 617.1 million km is significantly smaller than that of VY Canis Majoris.
Betelgeuse's measurements are approximately 950 times larger than our Sun, with a diameter of about 767 million miles (about 1.2 billion km). It is 10-20 times more massive than our Sun and emits between 7,500 and 14,000 times as much energy. Because Betelgeuse is a red supergiant, it is at the end of its life.
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.
Either way, it seems likely that Betelgeuse will be the Milky Way galaxy's next supernova but this wouldn't happen anytime soon. It could even be another 100,000 years before Betelgeuse's light is finally extinguished.
Now consider this: It's believed that Betelgeuse, a giant red star in the constellation Orion, is approaching the end of its life cycle. Most scientists believe it will become a supernova in the near future.
Betelgeuse is located approximately 640 light-years away from our planet. Although this might seem relatively close on an astronomical scale, it is far enough to significantly reduce the direct impact of a supernova.
“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 also one of the largest stars visible to the unaided eye. It's about 700 times the size of the Sun and around 15 times more massive. In fact, Betelgeuse is so giant that, if we replaced our Sun with Betelgeuse, it would stretch past Jupiter's orbit.
Beetlejuice is able to change shape, transform and conjure objects, teleport, and perform other feats of magic, although his powers can be reduced by various circumstances, such as when he feels fear, or when his head becomes separated from his body.
According to the Nine Planets report, UY Scuti is known to be the largest star in the universe with an estimated radius of 1.188 billion kilometres which is 1700 times larger than the Sun.
The red hypergiant VY CMa is bigger than Betelgeuse and belching out vast clouds of dust. When it comes to star sizes, there are dwarfs, there are giants, and there are supergiants. And then there are hypergiants. These are very massive stars that live fast, die young, and go out with an enormous bang: Supernovae.
The largest known 'object' in the Universe is the Hercules-Corona Borealis Great Wall. This is a 'galactic filament', a vast cluster of galaxies bound together by gravity, and it's estimated to be about 10 billion light-years across!
Astronomers have discovered what may be the oldest and most distant galaxy ever observed. The galaxy, called HD1, dates from a bit more than 300 million years after the Big Bang that marked the origin of the universe some 13.8 billion years ago, researchers said on Thursday.
Astrophysicist Robert F. Wing did an in-depth look on the largest stars, recognising Antares, Betelgeuse, Mu Cephei, and VV Cephei A as well-accepted largest stars, while also looking at other stars known for cool temperatures and high brightness like VY Canis Majoris and NML Cygni.
Will its supernova destroy Earth? Whenever Betelgeuse does blow up, our planet Earth is too far away for this explosion to harm, much less destroy, life on Earth. Studies indicate we'd have to be within 160 light-years of a supernova for it to harm us. And Betelgeuse is perhaps four times this distance.
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.
Less than 10 million years old, Betelgeuse has evolved rapidly because of its large mass and is expected to end its evolution with a supernova explosion, most likely within 100,000 years. When Betelgeuse explodes, it will shine as bright as the half-Moon for more than three months; life on Earth will be unharmed.
Betelgeuse is undoubtedly a red giant star that has already burned through its primary fuel hydrogen and is now fusing helium in its core into heavier elements. The point at which a star runs out of hydrogen in its lifetime is unmissable.
“The star's final fate depends on how much material is left after the supernova event,” Nasa said. 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.
Jupiter's perigee – or closest point to the Earth for 2023 – comes at 21 UTC (4 p.m. CDT) on November 1-2. That's when the distance between the Earth and Jupiter will be at its least for 2023.
