Alpha Centauri B is the most brilliant object in the sky and the other dazzling object is Alpha Centauri A. Our own Sun is visible to the upper right. It is also the lightest exoplanet ever discovered around a star like the Sun.
The results will appear online in the journal Nature on 17 October Alpha Centauri is one of the brightest stars in the southern skies and is the nearest stellar system to our Solar System—only 4.
It is actually a triple star—a system consisting of two stars similar to the Sun orbiting close to each other, designated Alpha Centauri A and B, and a more distant and faint red component known as Proxima Centauri. Since the nineteenth century astronomers have speculated about planets orbiting these bodies, the closest possible abodes for life beyond the Solar System, but searches of increasing precision had revealed nothing.
The star appears so big just because of the scattering of light by the telescope's optics as well as in the photographic emulsion.
Alpha Centauri is the closest star system to the Solar System. The effect is minute—it causes the star to move back and forth by no more than 51 centimetres per second 1. This is the highest precision ever achieved using this method.
Alpha Centauri B is very similar to the Sun but slightly smaller and less bright. The newly discovered planet, with a mass of a little more than that of the Earth, is orbiting about six million kilometres away from the star, much closer than Mercury is to the Sun in the Solar System.
The orbit of the other bright component of the double star, Alpha Centauri A, keeps it hundreds of times further away, but it would still be a very brilliant object in the planet's skies.

As we approach Alpha Centauri we pass a faint red star, this is Proxima Centauri, the closest star to Earth and the faintest component of a triple star system. The final part shows the bright double star Alpha Centauri A and B with the Sun visible in the background.
Alpha Centauri B is known to be orbited by an Earth-mass planet, the closest exoplanet to the Solar System. The challenge astronomers now face is to detect and characterise a planet of mass comparable to the Earth that is orbiting in the habitable zone around another star.
The first step has now been taken. Our other HARPS results, and new findings from Kepler, both show clearly that the majority of low-mass planets are found in such systems. We live in exciting times!About Zecharia Sitchin.
