The Alpha Centauri system consists of three stars orbiting each other. Alpha Centauri A and B are sunlike stars standing close by. Sometimes Alpha Centauri A is closest, and sometimes it is Proxima Centauri. At the moment its Proxima Centauri, a red dwarf orbiting Alpha Cantauri A and B. Its about 5% nearer to the sun than Alpha Centauri A. The distance sun Alpha Centauri is about 4.3 - 4.5 ly.

Proxima Centauri.
The Alpha Centauri system is composed of three stars. Alpha Centauri A and B are close together, Sun-like stars.
Alpha Centauri C is Proxima Centauri. It is a red dwarf that appears to orbit the other two, and at present is 1/20th closer to the Sun.

The closest known star after that is Proxima Centauri, a component of the triple star system denoted Alpha Centauri (the system looks like a single star to the naked eye).

Alpha Centauri is the star system. Proxima Centauri is one of three stars in that system and is the closest star to Earth (..next to the sun of course..)

Proxima (which means "near") Centauri. Alpha Centauri is a little further out.
