At a mere 430 light-years away, Betelgeuse has a distinctively reddish glow and is one of three stars that make up the Winter Triangle asterism, and it marks the center of the Winter Hexagon.
Betelgeuse is a extremely brilliant, supergiant star. The star will ultimately have to pay a costly price for its brilliance. The star will become a Supernova.
So… Yes, an explosion is in Betelgeuse’s destiny.
What will happen to the Earth when Betelgeuse turns Supernova? A Betelgeuse supernova will have little or no adverse effects on Earth. Our planet is too far away for an exploding Betelgeuse to do us any harm. Experts say that we would have to be within 50 light-years of a supernova to harm us. There’s approximately 10 times that distance between the Earth and Betelgeuse.
Would a person be able to see it from Earth? A person of the planet would see an amazing sight in the night sky, an extremely bright star. It will possibly be as bright as a full moon for a few weeks or months, and would probably be visible in broad daylight.
When will this happen? Possibly tomorrow, or millions of years in the future. No one really knows.
