Betelgeuse is a massive red supergiant about 640 light-years away in the constellation Orion. It’s one of the largest stars visible to the naked eye and is nearing the end of its life, expected to explode as a supernova sometime in the next idk years. Siwarha is a theorized companion star to Betelgeuse that is around the pre-main sequence phase of its life it is thought to be larger and more massive than the Sun atleast an F type star and orbits relatively close to betelgeuse at least around or
