Looking out across the Orion arm of the Milky Way, the distance to Betelgeuse is about 400-500 ly away. Betelgeuse, the 9th brightest star in the sky, is a red supergiant. A giant star is acting strange, and astronomers are buzzing The red giant Betelgeuse is the dimmest seen in years, prompting some speculation that the star is about to explode. When Betelgeuse explodes it will appear as bright as the moon in the night sky for several weeks and may even be visible during the day. Supernovas produce deadly bursts of gamma ray radiation but fortunately Betelgeuse is too far away to cause any damage to Earth. A spacecraft traveling at 17 km/s (the speed of Voyager 1, currently the fastest spacecraft) would take about 8 million years to get to where Betelgeuse is now.

Why does a star such as betelgeuse which is located far from earth have a much greater absolute magnitude than apparent magnitude? But getting a distance measurement for this star has been no easy task. It is over 400 light years away, so you might think that people would see it long after it actually happens? According to Philip’s Astronomy Encyclopedia, Betelgeuse is 427 light-years away and measures about 500 times the diameter of the Sun (that is, just under 700 million kilometers). O'Gorman/P.
Betelgeuse’s distance was initially measured by the parallax effect it had on Earth. However, there are some exceptions such as Betelgeuse. One way to evaluate the risk is to look at the consequences of past nearby supernovas. Question: If Betelgeuse explodes right now, could we see it with naked eye? Ordinarily, the fixed stars are so far awaythat we cannot measure their apparent diameter. Even at the low end of the distance estimates, Betelgeuse is too far away to do significant damage to Earth. As one of the largest known stars, Betelgeuse is truly a giant – 14 times more massive than our sun and 800 times its diameter.
