Assuming (always a dangerous practive) a rocky planet, with its apparent mass, its gravity would be greater than Earth’s. I haven’t done the math (probably won’t), but I would guess it to be 3 to 4 times that of Earth. So, a 150 lb. human would weigh from 450 to 600 lbs. Hmmmmm. wonder what they would look like?

Whatever lives there would probably be very low to the ground.

lol. Thank you for that. I follow a lot of these exoplanet threads and keep hearing about 'Earth-like' planets that are 8 times as big as the Earth. But they seem to always pass over the fact that 8 times the size = 8 times the gravity.

Not very 'Earth-like' to my mind.

Godspeed

Probably much more muscular, really would have to be.
