Rigel or Beta Orionis is a blue/white supergiant star of spectral type B8lab.

It is 754.81 milliarcseconds. Also, the star is Rigil Kentaurus, not Rigel which is the name of another star.
Proxima Centauri Rigil Kentaurus Barnard's Star
Alpha Centauri, also known as Rigil Kentaurus or Toliman, resides in the constellation of Centaurus, the centaur. It is quite far south in the sky and is only visible in the southern hemisphere. It is a circumpolar star of the south pole and reaches its highest point in the sky in June.
Any time you see something, with your eyes or with an instrument, it is because light from the object reaches you. This light takes a while to reach you; if the object is at a distance of 30 centimeters, it will take a nanosecond; if it comes from the star Rigil Kentaurus, it will take over 4 years, and if it comes from the galaxy M31, it will take 2-3 million years. That means that if we see the light from a distant star, it may already be dead (from a certain point of view - see the definition of simultaneity in the Theory of Relativity).
Alpha Centauri the biggest start of the 9 star of Centaurus Constellation. The 3rd brightest star in the sky; also known as Rigil Kent or Rigil Kentaurus. It is a yellow main-sequence star of the same spectral class (G2 V) as the sun and of about the same size and mass; its apparent magnitude is −0.26. _______________________________ Alpha Centauri is the brightest by visual magnitude, meaning that it LOOKS brightest; this is because it is the 2nd closest star to the Sun. (Proxima Centauri, the nearest, is an invisibly-dim red dwarf.) But as noted above, Alpha Centauri is really a quite ordinary star.The brightest star in Centaurus by absolute magnitude is the unnamed star HD119796, which is over 11000 light years away. At that distance, it is at the edge of naked-eye visiblilty.Beta Centarui, also called Hadar, is the 2nd brightest star in Centaurus by absolute magnitude. It is over 100 times further away than Alpha Centauri at 525 light years distance. But it is also the 2nd brightest in terms of visual magnitude.

The Star system Alpha Centauri, whose proper name is Rigil Kentaurus, is often shortened to "Rigil Kent". Now that "ya no it", y not learn more about astronomy! -Posted by Tim "Mr. Science" Perkins, from theMrScienceShow.com
