The triple-star system Alpha Centauri is the closest star system to Earth. But could humans ever travel there?

Alpha Centauri is host to two sun-like stars, and a third star – the red dwarf Proxima Centauri, which is already believed to have one planet in a Goldilocks orbit, discovered in 2016.

Alpha Centauri is also the very closest system in the galaxy, lying just 4.37 light—years away and providing a uniquely intimate perspective on any possible planets there.

Our sun's closest star system, Alpha Centauri, is "almost certainly" home to small Earth-like planets capable of harbouring alien life, scientists have claimed. Alpha Centauri, which is "only" 24. ...

If the nearest star system, Alpha Centauri, does harbor rocky planets similar to Earth as new findings suggest, there exist a host of ways to get us there, in theory.

So, while humans will probably never reach Alpha Centauri, it's possible that spacecraft designed to go a much smaller fraction of the speed of light could reach these stars in a human lifetime.

Scientists René Heller and John Armstrong contend that there might be a planet even more suitable for life than Earth 4.3 light years away orbiting the star Alpha Centauri B.

Alpha Centauri Bb's extreme closeness to its parent star probably gives the planet a surface temperature around 2,240 degrees Fahrenheit (1,227 degrees Celsius), making it unsuitable for life ...
