If a person with a mass of 55kg was to travel to Jupiter or Pluto, the effects of gravity would be very different from those on Earth. Gravity is the pull that a planet exerts towards its centre. Gravity depends on mass. Jupiter has more mass than Earth, so its gravity is two and a half times greater. Pluto is much smaller than Earth and so the force of gravity on Pluto is weaker than it is on Earth.
