Alpha Centauri b is the second planet that orbits the star groupAlpha Centauri. Alpha Centauri b, also known as Alpha Centauri II or even 'The AC' in reference to its temperate climate is an Inner Colony world with large populations Alpha Centauri b from high orbit. and several cities. It...
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...
Alpha Centauri B may be close enough to Proxima Centauri for liquid water to exist there. However, scientists aren’t ready to say the star is safe for human life. Due to stellar flares (恒星耀斑) from Proxima Centauri, A...

Alpha Centauri A is the primary and brightest component. It's a yellow type G2 star similar to the Sun, but slightly larger and about 60% more luminous. Alpha Centauri B is an orange type K1 star, slightly smaller than the Sun and about half as luminous. The pair orbits each other ...

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 B is an orange K2-type star, slightly smaller than the sun. Proxima Centauri is a red dwarf about seven times smaller than the sun, or one-and-a-half times bigger than Jupiter. [The Brightest Stars in the Sky: A Starry Countdown] Historical observations The star was ...
European astronomers have discovered an Earth-mass planet orbiting the star Alpha Centauri B, a member of the closest star system to Earth. In this artist’s illustration, Alpha Centauri B is the most brilliant object, and Alpha Centauri A is in the lower left. The Sun is the tiny...
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. But it’s still not too different from our sun. ALPHA CENTAURI C (PROXIMA CENTAURI)is a smaller red dwarf star with a muc...
