Alpha Centauri is a binary, possibly triple, star system
See related link for a pictorial.
Yes, Alpha Centauri is significantly larger than Earth. Alpha Centauri is a star system that includes three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. The stars in this system are much larger and more massive than Earth, with Alpha Centauri A being similar to our Sun in size and mass. In contrast, Earth is a terrestrial planet, much smaller than any star.
be larger than Alpha Centauri and farther away from Earth
No. Alpha Centauri is much, much further away than Mars.
The diameter of Rigel Kentaurus, also known as Alpha Centauri, is estimated to be about 1.2 million kilometers. It is a binary star system composed of two stars, Alpha Centauri A and Alpha Centauri B, with Alpha Centauri A being slightly larger and more massive than our Sun.
Alpha Centauri is a binary star system with two stars ("A" and "B") nearly the same mass as the sun. Alpha Centuri A is 1.1 times the mass of the sun (bigger), while Alpha Centuri B is 0.9 times the mass of the sun (smaller).
Alpha Centauri is a binary star system, commonly known as Alpha Centauri ABAlpha Centauri A is about the same size and age as our Sun with a spectral type of G2VAlpha Centauri B is about 14% smaller that our Sun and a lot cooler having a spectral type of K1VThere is a third star, not surprisingly called Alpha Centauri C or Proxima Centauri which is the closest star to Earth.See related link for more information.
Alpha Centari is the nearest star to the Solar System's Sun. Alpha Centari is thought to be in the order of at least 4 to 7 billion years old. The Sun's age is estimated to be at the low end 4.6, and thus likely to be much younger. Another difference is that Alpha Centari is really a binary star system, while the Sun is the only star in the Solar System.
Alpha Centauri
Actually, Alpha Centauri is one of the brightest stars in the sky. In general, stars are much dimmer than our Sun, mainly because they are very far away.Actually, Alpha Centauri is one of the brightest stars in the sky.

Our Sun appears brighter than Alpha Centauri B because of its proximity to our point of view. We are much closer to our Sun then any other star which means that our Sun will be much brighter then everything else in the sky.

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.
