Distance to Proxima-Cenaturi = 3.995 x #10^13# km

Explanation:

Sun is the Nearest Star to us at a distance of 149 million km at an average given the elliptical orbit.

The Star closest to the Sun-Proxima-Centauri is 4.25 Light-Years away.

1 Light-Year = 9.4 x #10^12# km

Distance to Proxima-Centauri = 4.25 x 9.4 x #10^12#

Distance to Proxima-Cenaturi = 3.995 x #10^13# km
