Have you ever looked up into the night sky and wondered, is there something more out there? Well I have a story for you. It's a story of a star system just 4.37 light-years away called Alpha Centauri and its smallest star, Proxima Centauri, around which a planet, Proxima b, orbits. And guess what? Recent studies have indicated that this planet is not only capable of sustaining life, but may even already be home to intelligent life forms!
So buckle up, we're about to explore the secrets of Proxima Centauri together.

If you looked up into the night sky, you would have a hard time picking out Alpha Centauri A and B, two stars located only 23 times farther away from each other than the Sun is from Uranus. In the ranking of the brightest stars in our night sky, Alpha Centauri takes 3rd place! But while it may be difficult to dissociate them with the naked eye, this fascinating pair of stars has been the subject of close research and speculation for centuries, offering astronomers a unique opportunity to study two stellar bodies in close proximity.
Alpha Centauri A and B are both members of the Alpha Centauri star system, a binary star composed of two yellow-white stars, and are located 4.3 light years away from our Sun. They sit very close to each other in space, at just one tenth of a light year apart. Alpha Centauri A is the slightly brighter of the two, and both stars are very similar to the Sun in terms of size and temperature.
