No. Alpha Centauri is much, much further away than Mars.
4.3 light years===========================Sorry. "Light year" is an answer to "how far", not "how long".Alpha Centauri is about 4.4 light years away from our solar system and everything in it,which means that it takes AC's light about 4.3 years to get here.
Let's get our nomenclature right here. Alpha Centauri is a triple star system: Alpha Centauri A and Alpha Centauri B are a fairly close double of stars roughly like the Sun, and Alpha Centauri C is a much dimmer red dwarf orbiting the pair at a considerably greater distance. It just so happens that C's orbit brings it at times closer to the Sun than any other star that we currently know about. So Alpha Centauri C is sometimes itself called Proxima.
Because it's much closer to the Earth than the other stars. Outside our solar system - the nearest star to us is Alpha Centauri - which is 122,471,100,900 miles away. That's approximately 1,300 times further away from us as our Sun is !
Alpha Centauri (Rigil Kentaurus, Rigil Kent, or Toliman) is the brightest star in the southern constellation of Centaurus.It is actually a binary star, but appears to us as a single star.Alpha Centauri A has an apparent magnitude of -0.01Alpha Centauri B has an apparent magnitude of +1.33

be larger than Alpha Centauri and farther away from Earth
Alpha Centauri, which is 4.2 light years away from the Earth.
Alpha Centauri
The closest star we know of other than the Sun is Proxima (Alpha Centauri C) at about 4.2 light years. The next closest star after that is a tie, since it's a binary pair: Alpha Centauri A and Alpha Centauri B, both of which are about 4.4 light years away.
The "alpha" is a star's nomenclature means it's (usually) the brightest star in its constellation. Even if the constellations are apparently close, the stars could be any distance, since the constellation is only the two-dimensional "window" and doesn't tell us anything about the depth of the starfield. However, Alpha Sagittarii is about 180 light years from Earth. Since this is much further away than Alpha Centauri, we can more or less ignore the 4 light year distance between Earth and Alpha Centauri and say that Alpha Sagittarii is also about 180 light years from Alpha Centauri as well.
Proxima Centauri, which is probably part of the Toliman (Alpha Centauri) system.Proxima Centauri, which is probably part of the Toliman (Alpha Centauri) system.Proxima Centauri, which is probably part of the Toliman (Alpha Centauri) system.Proxima Centauri, which is probably part of the Toliman (Alpha Centauri) system.
At any given moment, it's one of the three stars making up the alpha Centauri system. The one that can get the closest is alpha Centauri C (aka Proxima), but depending on where it is in its orbit, it's possible for either alpha Centauri A or alpha Centauri B to be slightly closer than Proxima at a soecific point in time.
Alpha Centauri is a binary, possibly triple, star system See related link for a pictorial.
It is not.
To my understanding, the Alpha Centauri system contains two binary stars (Alpha Centauri A and Alpha Centauri B) and a third star Alpha Centauri C or Proxima Centauri (which is the closest star to our sun)
Alpha Centauri A
