Alpha Centauri is a triple star system The Alpha Centauri system contains the following 3 stars which are all bound by gravity: ALPHA CENTAURI Ais close to our sun in age and luminosity. Alpha Centauri A and B orbit closely to each other. ALPHA CENTAURI Bis smaller and dimmer than our sun...
Alpha Centauri is the closest star system to Earth and is made up of three stars and several exoplanets. We explore our stellar neighbors in more detail here.
Alpha Centauri is located just over four light years (光年), or about 25 trillion miles, from Earth. It would take today’s spacecraft more than 70,000 years to reach the star system. While this seems a very long distan...
A multiple star consisting of three stars in the constellation Centaurus. It is the star nearest Earth, at a distance of 4.4 light-years, and it is the third brightest star in the night sky. ♦ Prox·i·ma Centauri (prŏk′sə-mə) is the individual star in this system that ...
Rigel Kentaurus is the third-brightest star in the night sky. However, its brightness is due to the proximity of the system — commonly known as Alpha Centauri — which is the sun's closest neighbor, about 4.3 light-years away from Earth. Rigel Kentaurus is part of a triple star system,...
However, Alpha Centauri is not a single star; it's a triple consisting of two bright components and a feeble red dwarf. For most of their orbit, the main stars are easily split with small telescopes. This is also the nearest star system to the Solar System. Alpha Centauri (credit:- ...

Definition Alpha Centauri Bb is a putative planet orbiting the star Alpha Centauri B. Alpha Centauri is a triple stellar system consisting of a moderately close binary 伪 Cen AB, and a distant M dwarf companion known as Proxima Centauri at approximately 15,000 AU away from the binary. At a...
THE AGE AND MASS OF THE α HERCULIS TRIPLE-STAR SYSTEM FROM A MESA GRID OF ROTATING STARS WITH 1.3 M/M ☉ 8.0The grid is publicly available for retrieval. αHer is the second closest asymptotic giant branch (AGB) star to the Sun, and the variable luminous M5 Ib-II member of a ...
alpha Centauri A and B. This binary system is of obvious relevance to astronomers, astrobiologists, and space tourists of the future. A recent announcement by the Breakthrough Starshot project to study the feasibility of sending actual hardware to this triple-star system has increased our interest...
