If you convert light years to kilometers, it is roughly 207,993,609,020,736 km away (if exactly 22 light years away, which it isn't).
207,993,609,20,0.0184km/40,000km/h = 5199840225.5184 h
5199840225.5184 h/24 = 216660009.3966 d
216660009.3966 d/365.25 = 593182.7772665297 y
^ These are calculations for how long it would take us to reach that planet using "today"'s technology -- actually it's an overestimate of the timeframe. 593,000 years. This assumes a relatively typical shuttle-style launch, using acceleration boosts around the planets (already used), and assuming that develpers would go with solar sailing technology (already developed, not sure if manufactured). I'm fairly sure it would take a lot less time to get there usinf current technology but there is one HUGE hitch, and it isn't fuel by any means.
That hitch is maintaining Earth-like biology for a trip that would take something like a quarter million years even if the best techs were utilized. Actually I think there's one more tech available that would speed things up quite a bit.
Currently it would be much more likely to communicate with advanced life on that planet. Interestingly enough, "they" could have already heard our inadvertent "communications" quite some time ago, since we've been pumping out radio noise for a while (century+)--and deliberate communication more recently. On that note, if "they" tried to respond to us when "they" caught our messages, it's doubtful that we would have noticed the response. The reason is that we didn't do much listening until much later, when the SETI program came into place. Maybe we missed the calling
Most life (as we know it) doesn't communicate so well. Communications depends on how evolved life-forms are in a given habitat, and other factors. At 22 light years away, we can certainly learn a lot about the planet. We can send out probes ASAP, too.
Anyway we could terraform Mars at least as quickly as we could reach that habitable planet, given current technologies. It would be even better if we took drastic measures to clean up our planet and worried about moving elsewhere later
interesting..
