That and the the radius or the planet and since the acceleration goes as 1/r^2 a little bit of rounding there and a little bit of rounding in the mass could easily change the numbers that much.

So, get a crew that is ready to sever thier lives with this planet for the large amount of our time it would take for the journey, as when (and if) they get back, there would be a radical difference in the time that has elapsed.

Really, the only hurdle is creating a craft with enough fuel and supplys to travel the 20.5 light years to mount a mission to this planet. All you need to do is accelerate at a constant rate for the firsthalf of the journey, and decelerate at the same rate for the last half.

Yes, however, they need something to survive if they want to get there, and simply put, they need enough food supplies to survive the journey until they manage to reach the planet. Not to mention how they are going to go back to the Earth when they have enough information, unless they communicate by a high-reception radio that can reach the distance of that planet and therefore, need not to go back.

Is it just me or is everyone being closed-minded here? I mean, we have found life at the utter extremes of this planet. Boiling hot, freezing cold, and extreme pressure would all kill you or me, but there are things that thrive on them. Who's to say that Jupiter doesn't host some kind of bacteria or even something more complex, eeking out a living in the swirling gasses or miles below them on the surface?

No, dumbass. YOU would have to cope with it. I'm sure whatever lives there doesn't even notice. If it came here, it would have to cope with lower gravity and less radiation. (Incidentally, wouldn't radiation increase the rate of mutation, thus accelerating evolution?)

YES.

This is quite intresting, time to get some science geeks and my teacher in on this info. +1 for human kickassery.

Am I the only person extremely underwhelmed by this discovery? They didn't actually see it, they noticed an anomaly in a spectroanalysis of the star. They think there's a planet there because something was/is affecting the way the star appears to behave. For all we know it could be a Buick sized lump of dark matter or some kind of sub space anomaly or any of several things Star Trek tells us might be possible. And for all the talk of "oooh the water is probably liquid there" we don't even know if there's any water at all. All we do know at this point is that something is probably there.
