 Betelgeuse is a red supergiant star, about 650 light years away. It is //enormous//; imagined at the center of our solar system, its surface would lie beyond the asteroid belt and it would engulf the orbits of Mercury, Venus, Earth, Mars, and possibly Jupiter. This size comes at a cost; it’s only 10 million years old, but it has already shed a significant fraction of its outer layers, and is well on its way to a spectacular supernova, probably within the next 100,000 years. Betelgeuse is a red supergiant star, about 650 light years away.
