Abstract: This paper uses an inductive method to investigate the factors responsiblefor variations in planetary-rotation periods. I began by showing the presenceof a correlation between the masses of planets and their rotation periods. ThenI tested the impact of planetary radius, acceleration, velocity, and torque onrotation periods. I found that velocity, acceleration, and radius are the mostimportant factors in explaining rotation periods. The effect of mass may berather on influencing the size of the radii of planets. That is, the larger themass of a planet, the larger its radius. Moreover, mass does also influence thestrength of the rotational force, torque, which may have played a major role insetting the initial constant speeds of planetary rotation.
