Beta Centauri, also known as Hadar, is a binary star system consisting of two stars orbiting around a common center of mass. The shape of individual stars in the system is approximately spherical, as they are massive celestial bodies that undergo nuclear fusion to produce energy.
Alpha Centauri, Beta Centauri, and Proxima Centauri are the three main stars that make up the Centaurus constellation. Alpha Centauri is the closest star system to Earth, while Proxima Centauri is the closest known star to our solar system.
Alpha Centauri A and Alpha Centauri B form a binary star system, while Proxima Centauri is a red dwarf star that is located further away from the binary system. Together, these three stars make up the Alpha Centauri system, which is the closest star system to the Sun.
Polaris (the North star - Alpha Ursae Minoris) is a triple star system, but appears to us as a single star. Alpha Centauri is also another triple star system. And there are many more.
The nearest star to the celestial equator is Alpha Centauri. It is actually a triple star system consisting of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest of the three to Earth.
The nearest star to the Sun is Proxima Centauri, which is part of the Alpha Centauri star system. It is located about 4.24 light-years away from Earth.
All three members of this 'triple-star' system ... Alpha Centauri, Beta Centauri, and Proxima Centauri ... are listed as being located roughly 4.2 light-years from our solar system.
The term "Beta" isn't a star name -- it's a prefix that indicates that, of a group of stars, which one this one is. So there are Alpha cetauri, Beta Centauri, Gamm Centauri, etc...
There are no stars that I am aware of named "SMN". The nearest star to Earth is Proxima Centauri, and the next-closest stars are the binary pair Alpha Centauri and Beta Centauri.
Beta Centauri (Hadar or Agena) is the second brightest star in the constellation Centaurus and the tenth brightest star in the night sky.It has a spectral class of B1 and it is a blue-white giant star.
Alpha Centauri, Beta Centauri, and Proxima Centauri. Of the three, Proxima is the closest to us, hence the name (which means "nearest"). There is some dispute as to whether the system is actually a trinary star system, or a binary star system with Proxima as a relatively close neighbor that doesn't significantly interact with Alpha and Beta. As a result, the system is sometimes referred to as "AB Centauri", which designates a binary system.
The nearest other star is Proxima Centauri, at 4.2 light years away. Beyond that, Alpha Centauri and Beta Centauri are 4.5 LY away.
There is no single star called "alpha" or "beta". The brightest stars (usually) in each constellation are called "alpha" and "beta", followed by the Latin genitiv of the constellation; for example, "alpha centauri", "beta centauri", "alpha orionis", "alpha cruxis", etc.
Alpha Centauri, although it appears to the naked eye as a single star, is a binary pair. Together they are designated Alpha Centauri AB, the more massive and luminous in the pair designated Alpha Centauri A, the less massive and luminous Alpha Centauri B. Together, this pair is the third brightest "star" in the night sky. There is a third star probably interacting gravitationally with the pair, Proxima Centauri, also designated Alpha Centauri C, a red dwarf which is not visible to the naked eye but is the next closest star to our Sun. Alpha Centauri B has about 90% of the mass of our Sun and is about 45% as bright. Note that Alpha Centauri B is not the "second" star (second brightest) in the constellation Centaurus: that is Beta Centauri, which is itself a trinary star system.

Beta Centauri (also known as Hadar or Agena) is a blue white giant star in the constellation Centaurus.It has a spectral class of B1
Alpha Centauri is the nearest star system. Its a binary star system of Alpha Centauri A and Alpha Centauri B. If someone asks you what is the nearest star ? then the answer will be "proxima centauri" in my opinion. nearest star: proxima centauri nearest star system: Alpha centauri A and B. Some people believe that its a triple star system of Prixma, Alpha A and Alpha B. centauri.
Alpha Centauri, Beta Centauri, and Proxima Centauri are the three main stars that make up the Centaurus constellation. Alpha Centauri is the closest star system to Earth, while Proxima Centauri is the closest known star to our solar system.
