Okay, looks like as usual, I need to double check all my calculations with reality. I was a wee bit wrong. Okay very wrong. I recalculated it though.
Kepler 22b is assuming earth like density has 14 times Earth's mass and 2.4 of Earth's radius, meaning a gravity of 25 newtons or 2.5 times our gravity. That said I believe the density is less and there for the gravity would be less, and would contain more water and other volatiles, if it had half our density it would have half the above gravity. It would be a water world I have little doubt as all the terrestrial planetoids do not equal 14 earth masses, but if one includes the gas giant cores there would be more than enough. Still we would need to observe this star for fifty years to determine if there are gas giants in the system.
It looks like a wonderful world to travel to, it is a good thing that we can't yet.
