But how long does it take to get there? Just check this out.

Assuming (very reasonably) that you will have to travel at only a fraction of light speed, remember the fuel to accelerate and, what is more, if you want to stop when you get there, the fuel to decelerate.

Light speed is 6.706e+8 ( 186,000 x 60 x 60 = 6.696 x 10^8 ) miles per hour

__The nearest star is approx 4.3 light years away__, or 4.3 x 6,000,000,000,000 or approx 25.8 x 10^13 miles.

Thus 4.3 light years

**at 1% speed of light **would take 25.8 x 10^13 divided by 6.7 x 10^6 or 3.85 x 10^7 hours, or 1.6 x 10^6 days or

**4383.56 years.** Of course, getting up to speed and slowing down would add to the time, but I think we can probably neglect these. They probably amount to only a few hundred years. Remember we have shown elsewhere that light sails are out.

Any other ideas?
