Proxima Centauri, the nearest star to us, still 40,208,000,000,000 km. (Or about 268,770 AU.) We no longer use AU or astronomical units when we talk about distances to stars; light-years are usually used. … Alpha Centauri A & B is about 4.35 light-years away.

How long does it take to reach the nearest star?

In short, at a maximum speed of 56,000 km/h, Deep Space 1 will over 81,000 years Travel 4.24 light-years between Earth and Proxima Centauri. On this time scale, that would be more than 2,700 generations of humans.
