Planetary spin

All macro bodies in space are accreted from dense parts of galactic gasses. During their accretion, denser parts approach each other and other accreting bodies under mutual gravitational attraction in random directions. As the body becomes denser, it develops linear motion at very high linear speed. Simultaneously, the body also develops an apparent spin motion in a resultant direction of directions of movements of its parts. Rotary motion of a body requires diametrically opposite points (in rotating planes) on its surface to move in opposite directions. However, due to very high linear speed of the body, every point on it moves in the same direction and slight differences in linear speeds of diametrically opposite points on the body produces the appearance of the body spinning about its central axis. After a planet enters its orbital path, direction of its apparent spin motion is gradually stabilized in the plane of its orbital plane. Similarly, spin motion of a planet is apparent only about its central axis. Part of central force on a planet, orbiting about a central body, produces the torque on it to cause planet’s apparent spin motion. Torque applied on the planet during its motion in alternating half cycles of orbiting path are in opposite directions. Therefore, depending on the values of torques in opposite directions, resulting apparent spin motion of a planet may be in either direction or the planet may have no apparent spin motion at all.
