ONLY 22 lightyears?
You do realize it still takes 95,000 years for us to reach that with our current mainstream technology, right?

Only 22 light years! Why, we could go and be back in time for the Super Bowl!

Light travels at 186,000 miles per second, so how far does light travel in a year? Yeah you might make it back in time for super bowl 20,000+. By the time you got back to earth you would find earth had become the Planet of the Apes.
So the round trip to this star and back will actually take more like 771,550 years, and the McDonalds fries would not have decomposed yet.
It can be argued that an interstellar mission which cannot be completed within 50 years should not be started at all. Instead, assuming that a civilization is still on an increasing curve of propulsion system velocity, not yet having reached the limit, the resources should be invested in designing a better propulsion system.
This is because a slow spacecraft would probably be passed by another mission sent later with more advanced propulsion.[2] On the other hand, Andrew Kennedy has shown that if one calculates the journey time to a given destination as the rate of travel derived from growth (even exponential growth) increases, there is a clear minimum in the total time to that destination from now (see wait calculation).[3]
Voyages undertaken before the minimum will be overtaken by those who leave at the minimum, while those who leave after the minimum will never overtake those who left at the minimum. Any civilization traveling to an interstellar destination can look forward to a unique date that is best to leave, and one that is the most efficient with cost and time.
The system has much lower abundances of heavy elements (elements heavier than hydrogen and helium), such as iron, carbon and silicon.

"The planets coming out of Kepler are typically thousands of light-years away and we could never send a space probe out there," Vogt said. "We've been explicitly focusing on very nearby stars, because with today's technology, we could send a robotic probe out there, and within a few hundred years, it could be sending back picture postcards."
