It is about 170 times more luminous than the Sun, while Pollux shines with 43 solar luminosities. A relatively close 34 light-years away, Pollux is just under two times the mass of our sun, almost nine times the diameter of the sun, and about 30 times the suns brightness in visible light. That means, Pollux will throw its outer layers away creating a planetary Nebula, and the remains will collapse into a white dwarf.
