Quiz on Alpha Centauri

Alpha Centauri is the closest star system to our Solar System and one of the most fascinating in the night sky. It lies about 4.37 light-years away from Earth and is located in the constellation Centaurus. Alpha Centauri is actually a triple star system consisting of three stars — Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.

Alpha Centauri A and B are Sun-like stars that form a binary pair, orbiting each other, while Proxima Centauri, the third and faintest star, is a red dwarf that orbits farther away. Interestingly, Proxima Centauri is the closest individual star to Earth and has at least one known exoplanet, called Proxima b, which may lie within its habitable zone — where liquid water could exist.

The Alpha Centauri system has long fascinated astronomers because of its proximity and potential for hosting planets that might support life. It serves as a key target for future space exploration and interstellar missions aimed at studying nearby stars and their worlds.
