The distance has been generally presented in Light-years, which is the distance light travels in one-year. The distance to Alpha Centari is 4.7 light-years (alpha Centari is 4.3 light-years distance).
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.
From Sun to Alpha Centauri
Alpha Centauri, which is 4.2 light years away from the Earth.
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.
Alpha Centauri is the closest star system to Earth, located about 4.37 light-years away in the constellation of Centaurus. It consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest known star to the Sun.
Alpha-Centauri Distance from Sun/Earth of alphaa-Centauri from the Earth is now reckoned at 4.396 light-years or 4.159×1013 km.) It is the same stella type as our Sun.
Alpha Centauri is 4.37 light-years away from Earth, which means it takes light, the fastest thing in the universe, 4.37 years to travel that distance. Although light travels at a speed of about 186,282 miles per second, the vastness of space makes this journey take years.
Proxima Centauri (note spelling) and Alpha Centauri are stars in a trinary some 4.3 light years from earth (at the present time).
Proxima Centauri Alpha Centauri A Alpha Centauri B
The nearest star system to ours is the Alpha Centauri system, located about 4.37 light-years away from Earth. It consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest of the three to our solar system.
Alpha Centauri AB is a binary star system. It is 4.37 light years away from our Sun. Both Alpha Centauri A and Alpha Centauri B are in close orbit around each other, so the same distance is valid for both.
Alpha Centuri is roughly 4.1626325x1018 centimeters from the Sun. The distance from the Earth varies depending on where we are in our orbit..
