Will the Betelgeuse supernova destroy Earth? No. Whenever Betelgeuse does blow up, our planet Earth is too far away for this explosion to harm, much less destroy, life on Earth. Astrophysicists say we'd have to be within 50 light-years of a supernova for it to harm us.

Will Betelgeuse star kill us?

With a smaller radius, Betelgeuse must be closer than once thought putting the Red Supergiant at about 530 light years. While 25% closer than older calculations, the star is still too distant to kill us if it blows up.

Will Betelgeuse affect us?
