of the planet is subjected to an inertial centrifugal force，which makes it appear as a flat rotating ellipsoid. The faster
the planet rotates，the greater the centrifugal force of inertia is. When the speed is greater than a critical value，
the planet will break. Based on the principle of minimum potential energy，the upper limit of planetary rotation
speed is strictly calculated.
