On the Source of Power for Satellite Rolling

The attitude control of artificial satellites will fail occasionally, and the satellite will roll at this time. So why will artificial satellites be accompanied by the rolling phenomenon when they lose control? This paper analyzes the gravity between planets, proposes the equivalent sphere of the planet's graviton emitted gravitons and the gravitational action point of the planet, and explains the separation phenomenon of the gravitational action point and the center of mass. Taking the earth and the moon as an example, the gravitational action point of the moon is at a radius 0.5 near the earth-moon gravitational action point on the moon and the center of mass of the moon, the gravity of the earth acts on the moon, which will cause the moon to produce a centripetal force orbiting the earth, and the moon will produce a reverse rotation force. For the rotation of the moon, since the gravitational action point is relatively fixed, the moon's center of mass rotates inversely relative to the gravitational action point of the earth and moon. According to the law of conservation of momentum, the linear velocity of the moon orbiting the earth formed by gravity formed by gravity formed by the moon's center of mass rotates around the gravitational action point, and they reflect that the angular velocity of the earth orbiting the earth is equal and opposite in the direction. This is the fundamental reason for the conservation of angular momentum of the moon's revolution. Under the combined action of the inertial force of the moon, the centripetal force of the earth and the rotation of the moon in the opposite direction around the gravitational action point, the moon's rotation will form an elliptical orbit. This article simulates the elliptical orbit of the moon orbiting the earth and the earth orbiting the sun. Through derivation calculations and simulations, more than 99% of the planet's gravity is used for planet rotation. Similar to the moon, artificial satellites are similar to the moon. While orbiting the earth, gravity will cause the satellite to rotate in the opposite direction to the rotation, which is the source of power for rolling in the event of failure of satellite attitude control.
