However, the orbit may be eliptical which could mean more dramatic differences between the extremes for that planet. The spin axis tilt impacts this as well. These things Kepler can't determine as far as I know. Besides that, us humans could not survive on that planet for the mere fact that our bodies would not be able to handle the strong gravity. Given the size, could someone do a calculation the weight a 200 LBS person would be?
Oh certainly the planet could be lifeless hunk of rock, but it is just that before this planet...there was never one that was even moderately interesting. Now we have a place that might be interesting to send a probe to...so maybe some research on how to get one one there might kick into higher gear and go beyond drawing some math on a chalk board.
Planet size isn't the only thing that would effect gravity either. Look at Uranus(LOL)...it is many times the size of earth, but due to the planets make up the gravity it has is theorized to be actually slightly less than earth's. If it's in the habital zone...then it is assumed it will probably be a rock or iron core though...so I would expect it to be a much higher gravity than earth too, but you can't rule it out. they didn't even expect the planet to be there in the first place.Edited by Vagrant Storm - 2/8/12 at 2:18pm
