Question 29
The diagram shows the relative strengths of gravitational force for planets of different masses. The size of each planet represents its relative mass. The arrow length indicates the relative amount of gravitational pull that each planet would exert on an astronaut in space.
Key: arrow length = relative gravitational pull; planet size = relative mass.
Which three planets shown have less gravitational pull than Earth?
