The description below the figure should be modified to warn readers who automatically are lead to imagine a gravitational field below the surface. To be clearer, if you imagine a small sphere rolling along a straight line when it is far away from the planet, you might think that when it comes closer it tends to fall into the depression as if it were subjected to a gravitational force acting vertically downwards as on the surface of the Earth. Instead, there is no force changing the trajectory of the ball, being instead the deformation od the surface.Demaag (talk) 11:38, 6 March 2011 (UTC)
