KIRKWOOD'S LAW.

The square of the number of times that each planet rotates during one revolution in its orbit is proportional to the cube of the diameter of its sphere of attraction.

The sphere of attraction is that within which the attraction of one planet is greater than that of the next interior or exterior planet.
