Precession of the earth through the zodiac constellations over the long cycle. What determines the direction of precession of a gyroscope? The direction a gyro will precess also depends on the direction the gyro is spinning. Precession is actually the result of two forces: angular momentum (spinning force) and the applied force (torque). The direction of precession is always offset from the direction of the applied force.
