Pollux has around 1.91 solar masses, almost twice than that of the Sun and about nine times its radius. As an Avox, he was charged for rebellion, and therefore forced to perform slave work. By stellar standards, thats super-short, but there are kinds of stars that can go supernova. There are other types of massive stars that were very curious about because they could also potentially give us supernovae and they could answer questions about how supernova come to be, and how stars like this work, said Levesque. C. The Sun is likely to become a supernova. The missions were intended to test procedures and technologies for moon flights and focused on aspects such as long-duration flights, rendezvous and docking. Its also a likely candidate for the next star to go supernova. Mira is hotter and bluer but intrinsically fainter than the Sun. To that direction, recent supernova spectra are examined and historical supernova Ia . However, its distance, and hence luminosity, is poorly known; its luminosity is somewhere between 55,000 and 196,000 times that of the Sun. In Greek mythology, Pollux was one of two brothers who appeared prominently among Jasons Argonauts. But even if it exploded tomorrow, don't expect the explosion to be noticeable anytime soon.
