17 Oct 2012 Astronomers spot the nearest known planet outside our Solar System, circling a star in the Alpha Centauri system just four light-years away.

Proxima Centauri, the smallest member of the Alpha Centauri system, is an M5.5-type star located 4.244 light-years away in the southern constellation of Centaurus.. The star has a measured radius

Alpha Centauri B has no known planets: planet Bb, purportedly discovered in 2012, was found to be an artifact, and a separate transiting planet has yet to be confirmed. In 2016 the International Astronomical Union designated Alpha Centauri A as Rigil Kentaurus, which comes from Rijl al-Qanṭūris, Arabic for “foot of the Centaur.” Proxima has one planet, Proxima Centauri b, the closest extrasolar planet, which was discovered in 2016.

Alpha Centauri A may have a Neptune-sized habitable-zone planet, though it is not yet known to be planetary in nature and could be an artifact of the discovery mechanism. Alpha Centauri B has no known planets: planet Bb, purportedly discovered in 2012, was found to be an artifact, and a separate transiting planet has yet to be confirmed. The new planet, officially Alpha Centauri Bb, has an orbital period of just 3.2 days, and lies just 6 million kilometers from its star. By comparison, Mercury has an 88-day orbit—and its closest approach to the sun is 46 million kilometers. This doesn't bode well for life on the surface, but where there's one exoplanet around a star, there A new study involving long-term monitoring of Alpha Centauri by NASA’s Chandra X-ray Observatory indicates that any planets orbiting the two brightest stars are likely not being pummeled by large amounts of X-ray radiation from their host stars.

They are rumored to sometimes put the pursuit of knowledge ahead of ethics. They start the game The planet appears to be orbiting Alpha Centauri A, which is a star a lot like our own Sun, though the conditions on the would-be planet are unknowable at this time.

Alpha Centauri (α Cen) is a triple star system located at a distance of 4.37 light years from Earth in the constellation Centaurus. It is the nearest star system to the Sun and hosts the nearest extrasolar planets to Earth.
