The exoplanet, TOI-715 b, is about one and a half times the width of Earth.

So, how much more weight would one be subject to?

[–] Brainsploosh@lemmy.world 9 points 2 years ago (1 children)

Assuming the same density, about three times as much gravity.

Gravity scales linearly with volume which scales with the cube of the width, (3/2)³ is about 3,4.

So we go there to train and come back as superheroes?

More like all our joints decay rapidly under the added stress, and we end up with crippling arthritis and an early grave. But maybe some generation of our descendants would be Bulrathi or Klingons or something, after some adaptation!

Genetic engineering to the rescue.
