As long as you are outside of a spherical mass, you can model its gravitational effect on you as if it were a point mass. This is assuming that both bodies are not small in relation to the magnitude of the gravity involved, else tidal forces to come into play. Edit: And people would probably not be able to deal with 3.6 gravities constantly pulling the blood out of their brains and into their feet. You would have to spend years working up to the ability to withstand that with any kind of consistency, I imagine. Maybe the first colony ship will be one of those that rotates to simulate gravity, and the inhabitants will spend the entire trip gradually dialing up the spin speed over the course of however many hundreds of years it would take to get there. That ought to do the trick. And only physically fit people could even set foot on the planet. What about, children, babies, elderly, infirm? | ||

Plus I don't think anyone is assuming there human's just like us living there. (even if there if life there)Who knows there could be some alien race that can withstand those type of environment's we just don't know. Edit: Unless someone was talking about from moving from Earth to there....Then yea that would be impossible. | ||

its parent star is located about 35 light-years away, making it relatively nearby I had to laugh at the thought they think 35 light-years is relatively nearby when I think even 500 miles is far. I am so small  | ||

At our best estimates, life is so extremely rare in the universe, that we will likely never (certainly not our generation but probably not even humans) see another intelligent sophisticated race. Sci-fi has ruined us! (although secretly I still hope that some sort of physics-bending science will come about that allows FTL travel and exploration! ) | ||

"you know all that money that we spend on nuclear weapons and defence each year? trillions of dollars. INSTEAD if we spend that money feeding and clothing the poor of the world, and it would pay for it many times over, we could as ONE race, explore outer space together, in peace, forever" ------GUNSHOT------DEAth!!!! | ||

You can start with the mass M goes as r^3. So r ~ M ^ (1/3) . Plugging that into F = mg = GMm/r^2. Gives you the surface acceleration as M^(1/3). So for constant densities this the new surface gravitational acceleration is (3.6)^(1/3) = 1.2 g. Not bad at all ^^. It should be noted that this is not necessarily the whole story. For one thing rocky materials become more compressed with additional pressure. For instance materials of identical composition at the Earth's center are more dense than those at the center of Mars. This would effectively decrease the radius and increase the surface gravity for a given mass. Alternatively...we do not, in general, know the relative abundance of lighter silicate (think rock) material to the denser metallic iron in any given planet found with this identification technique (note that this is different from the technique used by the KEPLER mission, which yields good predictions of radius and not mass). The Earth, Moon and Mars all have similar ratios of these two materials (which might be expected seeing that they formed from the same disk of material orbiting the sun. Mercury has a greater proportion of the heavier iron, for reasons that are not well understood. We have no reason to necessarily believe this would be a similar ratio in other solar systems, and this unknown could push the surface gravity in either direction. So I guess what I am saying is big error-bars, but probably not too uncomfurtable as far as super-gravity is concerned ^^. These are indeed exciting times. I dont hear too much about other missions, but I know the KEPLER mission has 1000s of "planetary candidates", many within in the Earth to super-earth size range. | ||
