Betelgeuse, a red supergiant star known for its significant dimming events and the potential to explode in a supernova, located in the Orion constellation. This video covers the behavior of Betelgeuse, highlighting its size, luminosity, and the recent observations that have led to speculation about its imminent future.

The probability that supernovae themselves can induce detectable ripples in spacetime detectable in gravitational waves is pretty unlikely to occur and to be detectable would likely require a LIGO type observatory in space on a magnitude of close to the Earth - Moon orbit. Ninety-Five percent of the mass of a Super Nova stay relatively close to the star during the gravitational collapse of the star and resulting expulsion of the outer layers of the star resulting in much of the mass collapsed into a white dwarf but still gravitationally stable in essence with relatively much the same spacetime gravitational annealing in place but expanding only due to the materials shed.

In answer to the title question, as far as we are concerned, not a lot. Because even light takes time to travel the vast distance, it would take a number of years for that light to reach us. So, Betelgeuse could explode now, and we wouldn't see the light of it until it reached us... As for the tag, 'We're not ready!', we don't have to be. Betelgeuse is too far away from us for any harmful effects to reach us. At best we'd have a second bright light in our sky during the day, but that's about it. That and the fact that the constellation Orion will forever be missing a key component, that is.

Actually because BeetleJuice is NOT a Main Sequence Star and is in its Red Giant phase and because its distance is greater than 320 light years away (the maximum for deriving distance by Parallax), there are some rather large error bars on its distance, somewhere between 550 light yrs and 650 light yrs. One might think that when Voyager traveled beyond Uranus, it would have faced its cameras at Beetlejuice to get a more precise Parallax distance measurement. Maybe that did happen.

If it exploded just now, what would happen to the earth? Nothing right now! Betelgeuse is some distance from us, Astronomers suggest 422 +/- lights, but the distance is debatable. Some astronomers suggest that the earth is too far from us but honestly that can be debatable. Let’s say it did blow and it has since gone supernova, we will not know for 500 years. However I saw a story about Polaris the north star, that star is acting up. But if we were much closer, better pray….
