Betelgeuse, in the constellation of Orion, lies just 427 light years from the Solar System. Like all red supergiants, it is a massive star nearing the end of its relatively short lifespan of perhaps just a few million years in total. It has a mass of around 14 times that of the Sun and varies in size between around 400 and 600 times the Sun’s diameter.
