Not really, even a really large planet like that would only have gravity that is 1.5X to 2X the gravity on earth due to how gravity works via the square of distance.
2X gravity is not all that bad, it would be like being overweight when fit and for someone who is fit you would get used to it.
Underwire bras required!
Also depends on how dense it is, right?
If mass goes as R-cube, gravity goes as R-squared, so surface gravity would be proportional to R, for equal denisity. All other things are rarely, equal, however. The earth is the densiest planet in the solar system, having an iron core. The Moon’s diameter, for instance, is about 3.67 times smaller than earth’s, but it’s surface gravity is about 6.05 times smaller because it is that much less dense.
If this planet has an iron core the size of earth’s and a lot of rock plied on top, it could have surface gravity much lower than earth’s. Either way, just as elephants and spiders exist on earth, complex life could exist on this planet. Even snakes.
Kepler measures light dips from transiting planets, a technique that gives the size, but not the mass of the planet. Doppler studies of its host star should reveal its mass as well.
This is what I was thinking also.
2G’s would not be too bad. 3 G’s would be sucky.
Nevermind...found it:
F = Mm/r^2
(Force of gravity = Mass (planet) x mass (person)/radius squared)
So until NASA figures out the composition of Kepler 22b, i.e. density, then we can’t know how much more a person would weigh.
Depends on if your knees are in good shape or not.
