    A planet 9 times the size of earth could still potentially host human life, we’d need to live high up in the sky so the gravity would be lower, but it’s possible

        Gravity becomes lower at higher altitudes, or what do you mean?

          The bigger aplanet, the further away its surface from its center of mass, which decreases gravity. A planet’s surface gravity is mostly affected by its mass and density. This is why Saturn, despite being much bigger than Earth, still have roughly the same surface garvity.
