The Kozai Mechanism (Lidov-Kozai Mechanism or Lidov-Kozai Effect) is an effect on a body's orbit by another body orbiting further from the primary body causing oscillations in Orbital Inclination and Eccentricity, i.e., a Kozai Oscillation (or LK Oscillation or Kozai Cycle). For example, an artificial satellite orbiting Earth, affected by the Moon. The mechanism is significant for some Asteroids, moons, and Extra-Solar Planets.
The effect was first described by Soviet, Michael Lidov in 1961 and Japanese, Yoshihide Kozai in 1962.
