Alpha Centauriâs surface temperature is a few degrees Kelvin less than our sun (that is, about 5770 k), but its greater diameter (about 25% more than the sun) and the overall larger surface area gives it a luminosity nearly 1.6 times that of our star.
That's two questions Alpha Centauri is our nearest star 4.36 Light years away so it would take you 4.36 years travelling at the speed of light to reach it. Don't really know how that converts to our fastest space craft a few centuries as a rough guess.
