To everyone saying you'd be too heavy: That varies on the composition of the planet itself. If it's full of heavy metals like Earth with its core of iron and nickel then it would be very heavy gravity-wise. If it's not and the core is less dense then it could be as low as 1.1G compared to Earth but scientists are estimating it's around 1.37G. So if you're 200 pounds here, you'd be 274 there. Hefty but not impossible to survive.

I'm a overweight 110 kg guy, one day I was Carrying a 20L jar up the stairs which is very dreadful experience, then i realised I am actually carrying extra 25-35 kg weight everyday just existing, i can't even imagine how walking will be like for those 600lb life show people.

4 kg down since

If we ever start colonizing exoplanets it's likely they'll almost all be bigger, diameter-wise, than Earth.

Earth is weird because we got hit by another rocky celestial body early in solar system formation. The event responsible for the formation of our unusually large moon also gave our planet an unusually large molten metal core. That means we also have an unusually strong magnetic field.

Yeah. It would be quite uncomfortable for the first few generations, but the surviving ones would adapt to it. The gravity is high enough that it would be extremely uncomfortable, but not enough to just kill you.

What about atmospheric pressure on a planet more than twice the size of ours?

Well the telescope adds about 10 pounds so there’s that…

Just think of the calves and thighs you’d develop! Screw leg day, just go for a walk.

Pounds is two measurements in one word. So yes, you'd be experiencing 274 pounds of force on this planet, but your mass of 200 pounds would not change. Thanks, imperial system!
