“Weighing in at about seven times the mass of Earth, “
I’m ready to move,,, but does that mean I’d weigh 1,400 pounds? That might be difficult to manage!
No, because the surface gravity is also a function of the distance to the centre. The G-force is directly proportional to the mass and inverse-square proportional to the distance. Assuming the same density as Earth, a world of seven times the mass would be roughly double the diameter. That would mean 7x Earth mass divided by 4, or just under 2g, so you’d only weigh about 400lb.
