One small problem. This planet is 620 light years away. It will take generation in space travel and a new generation of spacecraft to achieve star travel.
Not to mention whether they'll be interested in meeting us!
Just our luck. This planet is probably full of Amazonian women, or maybe the place where those green skin Orion Slave Girls live, and we'll never even get there in many generations even if we leave now. Oh well, my wife wouldn't let me keep one anyway.
