Approxiamtely 4.3 light years away
Proxima Centauri Alpha Centauri A Alpha Centauri B
Alpha Centauri is a triple star system. Alpha Centauri A, B & C or Proxima Centauri. Alpha Centauri A & B are 4.37 light years from the Earth whereas Alpha Centauri C is 4.243 light years.
Proxima Centauri is the closest star to Earth at a distance of about 4.24 light years away. It is part of the Alpha Centauri star system, which is the closest star system to our solar system.
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.
No; in fact, the Alpha Centauri system is the closest star system to Earth.The closest star to us is the Sun; the next-closest star is Proxima Centauri, part of the Alpha Centauri system.
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.
The nearest star to the Sun is Proxima Centauri, which is part of the Alpha Centauri star system. It is located about 4.24 light-years away from Earth.
The closest star to Earth after the Sun is Proxima Centauri, which is part of the Alpha Centauri star system. It is located about 4.24 light years away from us.
Alpha Centauri (Rigil Kentaurus, Rigil Kent, or Toliman) is a binary star systemAlpha Centauri A is a G2 star or yellow dwarf - very similar to our own SunAlpha Centauri B is a K1 star or orange dwarf.and possibly a triple star system.Alpha Centauri C (Proxima Centauri) is a M5 star or red dwarfAlpha Centauri (Rigil Kentaurus) is the brightest star in the southern constellation of Centaurus. Although it appears to us as a single object, Alpha Centauri is actually a binary star system.Alpha Centauri A has a spectral type of G2V - so it is a yellow dwarf.Alpha Centauri B has a spectral type of G2V - so it is an orange dwarf.
Polaris (the North star - Alpha Ursae Minoris) is a triple star system, but appears to us as a single star. Alpha Centauri is also another triple star system. And there are many more.
The nearest star to Earth aside from the Sun is Proxima Centauri, which is part of the Alpha Centauri star system located about 4.24 light years away from us.
The closest star (aside from the Sun) to Earth is Alpha Centauri. It is about 4.22 light years away from earth. Though we call our star "the sun" its actual name is Sol which is used for the phrase "Solar System". All others are just systems and aren't in any way "solar".
