Canopus

Alpha Carinae is the second brightest star in the sky after Sirius. It is one of the rare cases of a yellow-white giant, which either hasn't reached the red giant stage yet or has already exceeded it.
Canopus hasn't got enough mass for a supernova and will become a huge white dwarf at the end of its life, with a neon and oxygen core.
