The distance for α Centauri in light-years is 4.35

Proxima Centauri is the closest star to the Sun and is part of the Alpha Centauri star system, located 4.24 light-years away from Earth in the constellation Centaurus. Alpha Centauri A and Alpha Centauri B are the primary components of the Alpha Centauri star system, located 4.37 light-years away from Earth. Alpha Centauri A is slightly brighter than the Sun, while Alpha Centauri B is slightly dimmer.

The parallax angle of α Centauri is 0.7420".To calculate the distance in parsecs and light-years, we need to use the formula:

Distance (in parsecs) = 1 / parallax angle (in arcseconds)

Therefore, the distance for α Centauri in parsecs is:

Distance (in parsecs) = 1 / 0.7420" = 1.34 parsecs

To calculate the distance in light-years, we need to use the formula:

Distance (in light-years) = Distance (in parsecs) × 3.26

Therefore, the distance for α Centauri in light-years is:

Distance (in light-years) = 1.34 parsecs × 3.26 = 4.35 light-years
