Your thoughts: If you want to know more about Betelgeuse or other stars, share your questions in the comments below!
Will Betelgeuse explode into a supernova soon?
Betelgeuse is a red supergiant star and is nearing the end of its life. However, it is not known exactly when it will explode into a supernova. It could happen as soon as a few thousand years from now.
Will Betelgeuse’s explosion affect Earth?
When Betelgeuse explodes into a supernova, it will produce a dazzling display in the night sky, but it will have no harmful effects on Earth because it is located far enough away.
How big is Betelgeuse?
Betelgeuse has a diameter about 1,000 times larger than the Sun. If it were placed at the center of our solar system, its edge would reach the orbit of Jupiter.
