It would take us millions of years to reach there. Light from the sun takes 8 minutes to reach us. Do the math! Generations would die before human-kind would be able take its first step there. As a matter of fact, the fastest spacecraft that we have would take around 25 million years to get there which is 10 times more than the time, human beings have inhabited the earth.   Unless we find a quicker way to get there, our species would become extinct. For now, it is nearly impossible to even visit that planet.
