An excellent question, but not one that can be answered. Since Rigel (the white star in the "knee" of Orion) is a blue supergiant of about 17 solar masses, it will explode in a supernova when it dies. In fact, since Rigel is about 800 light-years away, it may already have done so, and the light could be on its way here even now. The bigger the star, the shorter the life-span. We know that Rigel will die before our own Sun does, but that doesn't narrow it down by much.
Rigel is a triple star system.
The Rigel star is a star in the Orion constellation. Rigel is the brightest star in the Orion constellation, and it is the seventh brightest star seen in the night's sky.
Determing the age of a star is a very difficut process, so too is calculating it's life span. Observations have shown that Rigel has left the main sequence and is in what is called the horizontal branch. The last stage in it's life. So a ball park figure of it's existence will be in the thousands rather than millions of years.
It is unlikely that a planet orbiting Rigel, a massive and bright star, could support life as we know it. Rigel's high energy output and short lifespan would likely make it challenging for a planet orbiting it to have stable conditions for life to thrive.

It will end its life as a type II supernova.

Rigel B is also a blue-white star but, unlike Rigel A, it is a main sequence star.

Rigel is a blue-white star, while Betelgeuse is a red supergiant star.
Rigel by far.
No. Proxima Centauri is the nearest star. Rigel is much further away.
