GENERAL KNOWLEDGE

Detailed explanation-1: -Of the three stars in the system, the dimmest-called Proxima Centauri-is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23 times the Earth-Sun distance.

Detailed explanation-2: -Although it looks bright through the eye of Hubble, as you might expect from the nearest star to the Solar System, Proxima Centauri is not visible to the naked eye. Its average luminosity is very low, and it is quite small compared to other stars, at only about an eighth of the mass of the Sun.
