Precession (disambiguation)

Precession refers to a specific change in the direction of the rotation axis of a rotating object, in which the second Euler angle (angle of nutation) is constant

Precession may refer to:

• Precession, one of the Euler rotations
• Precession (mechanical), the process of one part rotating with respect to another due to fretting between the two
• Larmor precession, the precession of the magnetic moments of electrons, atomic nuclei, and atoms about an external magnetic field
• Astronomical precession
  • Axial precession or precession of the equinoxes, the precession of the Earth's axis of rotation
  • Apsidal precession, the rotation of the orbit of a celestial body
  • Nodal precession, the precession of the orbital plane of a satellite around the rotational axis of an astronomical body due to the non-spherical nature of it.
• Relativistic Precession
  • Thomas precession, a special relativistic correction to the precession of a gyroscope in a rotating non-inertial frame
  • de Sitter precession, a general relativistic correction to the precession of a gyroscope near a large mass such as the Earth
  • Lense-Thirring precession, a general relativistic correction to the precession of a gyroscope near a large rotating mass such as the Earth
• Phase precession, a pattern of neuronal firing in relation to local neuron populations
