Betelgeuseball is a red supergiant star in the Orion constellation
(on his shoulder). He is very old, near the end of his life. His light takes 500 years to reach Earthball, so as far as we know he could have exploded in a supernova by now. It is said that when he does blow up, he will be brighter than Moonball in the sky. Saying his name three times makes him appear.
