Betelgeuse, aka Orion’s left shoulder, is an unfathomably large red hypergiant star and one of the brightest stars in our night sky. Betelgeuse has a diameter 887 times that of the Sun, and you could fit 700 million Suns inside of it or around a quadrillion Earths. Betelgeuse is rapidly shrinking, and scientists expect it to run out of fuel and go supernova within the next 100,000 years. When it does, it won’t hurt us — it’s on safe 640 light years away — but it will become as bright in our sky as a full moon!
