Das Sternensystem Alpha Centauri (auch Rigil Kentaurus oder Alpha Cantaurus gennant) liegt etwa 4,33 LJ von der Erde entfernt im Sternbild Centaurus, von dem sich auch sein Name ableitet. Bis heute wird darum gestritten, ob Alpha Centauri ein binäres
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...

‘tail’). Deneb is one of the biggest and brightest stars known, with a mass at least 25 times that of the Sun. It has a luminosity of between 60 000 and 250 000 times the Sun's brightness, depending on the accuracy of our distance estimates for it. It has very low proper motion...
Is there life in Alpha Centauri? As for the planet we have already found,Proxima bcreated a lot of buzz after its detection in 2016 because it is a bit larger than Earth (at least 17% more mass) and, crucially, is in the habitable zone. That alone does not give us enough information...
Once launched into space, the Starshot nanocraft will inflate a 1- to 4-meter spherical lightsail that will be sent speeding off toward Alpha Centauri when hit by a laser beam from Earth. Darius Farraye/CNET The second challenge is building a lightsail material that won't vanish into a puf...
IUE far-UV and Einstein Observatory soft X-ray observations for the red giant Arcturus and the nearby yellow dwarf Alpha-Centauri A, which are archetypes of solar mass stars in different stages of evolution, are compared. Evidence is found for neither coronal soft X-ray emission from the red...
