Just because you NEED something by a certain time does not prompt users to actually answer your question.
However, I'll give a few pointers.
Depending on which part of Alpha Centauri you intend to go to, there are three stars with different distances.
The speed of light is 299,792,458 meters per second.
At 1,516 the speed of light is 454,485,366,328 meters per second.
So all you have to do is calculate which Alpha Centauri you want to go to and divide the distance by the new speed.
Assuming that you start from earth, travelling that slowly to Alpha Centauri would take quite a bit of time. Alpha Centauri's about 4.367 light years away, which means at the suggested speed of 70,000 kilometers per hour, it would take you 673.26 centuries to get there. You definitely want to go much faster to get there.
About 4 years 5 months even at the speed of light.
4.37 years.
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.
First of all, there has never yet been any such thing known to earth as a starship. If an object left Cape Canaveral at 1/2 the speed of light, and maintained a straight-line course toward the place where Alpha Centauri would be when it got there, it would reach Alpha Centauri after the clock on the launch-pad had ticked off 8.8 years.
That's actually an easy calculation, if you state the problem correctly. Alpha Centauri is about 4.5 light years away. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year. Multiply all those numbers together to find out how many light-seconds it is to Alpha Centauri. The Moon is about 1.5 light seconds away, so divide by that to get the ratio.

The closest star to earth is the sun. The next closest is a red dwarf star called Proxima Centauri, much further away. The sun is around 8 minutes away at the speed of light, while Proxima Centauri is around 4.2 years away at the speed of light (light years).
Alpha Centauri is approximately 4.37 light-years away from Earth. To reach it in 130 years, you would need to travel at an average speed of about 0.033 light-years per year, or roughly 3.3% of the speed of light. This speed is significantly faster than any current spacecraft, highlighting the challenges of interstellar travel.
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.
Alpha Centuari is a star 4.4 light years away. Which is about 44 trillion km (44,000,000,000,000 km) or 44,000 Billion km. Its actually more like 42,479,700,000,000 km if you were exact.
Voyager's supposed maximum sustainable speed is "warp 9" which is assumed to be ( times the speed of light. Being that Alpha Centauri is 4.37 light years away from our sun then at warp 9 it would take 177.025 days, or approximately 6 months, to reach it. Chief Engineer Nerdberg, signing off.
