    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.

      The bigger a planet, the further away its surface is from its center of mass, which will decreases the force of gravity. A bigger planet does not equates to higher surface gravity, it’s a planet mass and density that mostly dictates this.
